    10. 10. Glossary• Reference to IS3043 – 1987 Reaffirmed 2006• “Earth” means the Ground, reference zero potential• Rely on the system earth to maintain the system voltage andnormal voltage supply• Equipment earth connects all non-conductive parts to protecthuman against electric shock• Class I protection – use of barrier/insulation and connection ofprotective conductor to equipment metallic enclosure in order toprotect against electric shock• Class II protection – beside of the basic insulation, addition layerof insulation apply to the enclosure. Therefore no extraneousconductive part. The additional layer is independent to the basicinsulation so that under failure of basic insulation, it offersadditional protection
    11. 11. Types of Earthing• Supply System – Neutral Earth• System Earth• Electrical Safety Earth• Lightning Earth• Generator Earth• Protection Earth (i.e. surge arrestor)• Telecom / Computer Earth• Shielding Earth• Integrated Earthing System (Advocated)• Electrostatic Earth (Clean Room / Hospital)• Cathodic protection (prevent rusty)
    12. 12. Functions of Earthing• Equipment Earth : Path for faultcurrent, lower touch voltage,protection against electric shock• Lighting Earth : Low resistance path todiverse the current under lightningattrack• Telecom Earth : Signal Earth,reducenoise and interference, stabilize DCsupply voltage and prevent electricshock• Computer Earth : reduce interference,maintain supply voltages
    13. 13. Earthing System• Two Alphabetic system description• First Alphabet – arrangement at Supply side– T represents system directly earthed, multi-earthed– I represents live part and earth path are separated, single pointearthed through high impedance• Second Alphabet – arrangement at Consumer side– T represents extraneous parts directly earthed, the earth pointindependent from Supply side– N represents extraneous parts connected to the protectiveconductor of supply• TN systems have two category:–S protective conductor and neutral conductor are two wires– C protective conductor and neutral conductor are the sameconductor
    14. 14. Earthing SystemTN-S‧protective conductor and neutral conductor are independent• All exposed metallic part connected with protectiveconductor PE• System Characteristics:– Low earth fault loop impedance– High earth fault current• Advantages: earth fault protection device operates faster;allow multi point earth, better earthing continuity; minimizethe use of earth fault relay because of low earth fault loopimpedance• Disadvantages: high earth fault level; under earth faultcondition, low power factor (high inductance of long cable)
    15. 15. Earthing SystemTN-C‧protective conductor and neutral conductor are combinedinto one• All exposed conductive parts connected to PEN• System Characteristics :– Low earth fault loop impedance– High earth fault current– More than one earth fault loops• Advantages : no earth wire required; allow of multi-pointearth, better earthing continuity; neutral never have floatvoltage; impedance of earth fault loop could be predicted• Disadvantages : If not multi-point earthed, and the neutralearth broken, the exposed metallic part may have floatvoltage; high earth fault level, intervenue the operation ofearth fault protective device, current operated type device isnot appropriated, voltage detected type could be employed
    16. 16. Earthing System
    17. 17. Earthing SystemTT• Supply side has one point earthing only• Exposed metal connected to consumer earth system• System characteristics :– High earth fault loop impedance– Low earth fault current– Utility company need not to provide earth forconsumer• Advantages : Under earth fault condition, higherpower factor; save earth wires• Disadvantages : high demand of E/F relays,individual earth system need higher investment,higher touch voltage; induce Potential gradient
    18. 18. Earthing System
    19. 19. Earthing SystemIT • System not connected with the earth (highimpedance earth or isolated earth), all exposedconductive part connect to earth• Neutral is totally isolated• Infinity earth fault loop impedance• Deemed less chance of electric shock• Many disadvantages: phase current equal to livevoltage (because of floating Neutral); no zeroreference, may cause arcing when earth fault occurs;to small of earth fault level, current type earth faultdetector cannot work properly
    20. 20. Earthing SystemModern Current Earthing System• Code 12 stipulated that electric equipment used to install its ownearthing protection system (TT system) and Main Earth Terminal shallconnected with utility company earth point. For instance, star oftransformer or metallic earth from supply cable

    23. 23. FACT ABOUT SOIL RESISTIVITY - The resistivity of earth mayvary over extremely wide limits, depending on the composition ofthe soil and the moisture content. Representative values are:General average 100 ohm-metersSwampy ground 10-100 ohm-metersSea water 0.01-1 ohm-metersDry earth 1000 ohm-metersPure slate 107 ohm-metersSandstone 108 ohm-meters
    24. 24. Earthing SystemEarth Electrode• Design concerns:• Resistance/impedance to earth• Heat capacity (during earth fault,max 40kA)• The potential gradient around the electrode during faults• Mechanical strength and ability in anti-corrosion• Earth electrode shall be rod / pipe, tape, buried copper plate,re-bar and superstructure• More than one electrode could be connected, the electrodecould be a mixed system• Long electrode generally effective than short one. Howeverelectrode too long does not have significant effects; largersize do not have great effects in earthing impedance
    25. 25. ALFREDKIM – EARTHELECTRODEAlfredkim Earthing Electrode is an ultraefficient low serge impedance groundingsystem and provides the desired lowmaintenance interface with real earth bycontinuously conditioning the surroundingsoil. And manufactured by using strip in pipepasses through hot dip galvanized processensuring 100% corrosive protection & waterresistant and ensures maximum conductivity.This is achieved by applying a thick layer ofZink coating (80-100 microns).
    26. 26. Earthing SystemElectric Shock Protection• Every premises shall have basic consideration to itselectric equipment’s safety – Electric Shock Protection• Means of electric shock – Direct contact or indirectcontact• Direct contact means direct touch to the live parts• Indirect Contact means human contact to non-conductivemetal, of which the extraneous part becomes live duringfaults• Electric Shock Protection shall meet the requirements inCode 11B including equipotential zones and automaticdisconnection under fault• IEC report 479-1(1984) had studied “The effects in injectof current into human and concerns on the currentmagnitude, duration and flowing path

    47. 47. DISCARD PIT TYPE EARTHING–SWITCH TO CHEMICAL PIPE EARTHING! The conventional copper pit type earthing is out of date because:-1. The water level is going down at most of the geographical areas & therefore one has to dig deep holes may be to the extent of 20-50mtr.2. The commonly used substances in pit type earthing were sodiumChloride known as common salt, soft coke & charcoal.3. The common salt (sodium chloride) is a hygroscopic substance & it gets dissolved in water & losses its hygroscopic properties whenbecome water itself.4. The salt is known to be a corrosive electrolyte which decays the pipe and the conductor used for earthing. Due to decay one does notget the consistent ohmic values.5. The soft coke & charcoal tend to become ash due to heavy heatgenerated by heavy electric fault currents generated in the system especially at higher voltages at 1.1kv, 3.3kv, 6.6kv, 11kv, 33kv, 66kv&133kv transmission distribution line & at substation.
    48. 48. 6. The heat generated is proportional to I2Rt (Time in seconds) e.g. if the faultcurrent of 10,000amps in the system with an earth resistance 2 ohms aspermitted by IS in 0.01 seconds is given as under.H=I2Rt H=10,000x10, 000x2x0.01=20, 00,000 calories =1053 °CThis much heat generated in one fault. Assuming 6 faults in a year. Then in aperiod of four year -24 fault occur , each fault generating 1053 °C & Above.7. Each fault of this magnitude will turn the soft coke/ charcoal into ashgradually in a period of 3-4 years. The earth system will deteriorate and givelarger value of ohmic resistance thereby endangering the entire installationconsequently people & property.8. If the ohmic values goes up from 2 to 3 ohms because of faulty earthsystems heat generated will be 30,00,000 calories (i.e. 1600 °C )this results thatthe pit type earthing is inefficient , not reliable & cause serious damage to life &property in a period of 3-4 years .
    49. 49. 9. It is therefore observed that separate watering arrangement required to be made for maintaining moisture through a separate pipe dug along the earthingsystem.10. Instead of water producing the moisture in the earth pit the additional quantity of water poured in with a natural rain fall will wash away the charcoal& the soft coke from its main position thereby it will further deteriorate the functioning of the earth system. 
    50. 50. Why install chemical earthing:The above points conclude that pit type earthing is out ofdate and it is being replaced and preferred over chemicalpipe earthing for reasons given below:-1. The pipe for the chemical earthing are generally 2 mtr or 3mtr in length therefore the earth bore need not more thanthe 250 to 300mm dia & maximum depth of 3mtr.2. The moisture is maintained at a small depth of 3mtr byusing ground enhancement material, commonly known asGBFC (Grounding Back Fill Compound).3. The efficacy of the chemical earthing to maintain the moisture which is essential for low ohmic values of earthing resistance is due to use of hygroscopic chemical likealuminum silicate etc. which absorb the moisture but doesn’t get dissolved in the water unlike salt.
    51. 51. 4. The heat generated due to electric faults developing heatof 1060 °C and above is resisted by CCM (CrystallineConducive Material) which can withstand upto 2500°C.5. The CCM is filled in the pipe of appropriate dimension of50mm or 80mm dia and sealed at both ends. It incorporatesthe earth conductor of GI strip of suitable size of 30x6mm or40x6mm depending upon the individual design ofmanufacturer.  
    52. 52. 6. The CCM filled in the pipe being a good conductor increases the fault current capacity of the system because the pipe is hollow but when filled with CCM itbehaves like almost solid pipe.7. The CCM resists cracking, warping, shrinking, or distortion even whentemperature exceed 2500 °C due to severe repeated electric faults which may happen in operations over the year. 8. The GI pipe used are adequately galvanized (80-100 microns) as per IS-3047 1987. 9. Zinc oxide will be formed during the use of the earth system. Zinc oxide hasfollowing advantages over the conventional earthing which uses the copperplate or copper conductors:-a) Zinc oxide so formed is insoluble in water.b) Zinc oxide has a unique Dielectric strength that exhibits semiconducting &piezoelectric dual properties. (Unlike in copper where the copper oxide is abad conductor of electricity & becomes powdered Red Oxide (Copper Oxide)under high fault current that generate high temperatures)
    53. 53. c) ZnO finds application in Varistors which are used toprevent voltage surges in the electronic devices like mobilephone.d) ZnO is not combustible & used as a fire extinguishantmaterial.CONCLUTION:- The industry, project managers & theelectrical consultants find it very convincing to use & specifythe chemical pipe earthing which is convenient to install, nomaintenance what so ever with a long life of over 15 years.
    54. 54. a) Sub: Install ALFREDKIM CHEMICAL EARTHING. PreventElectrical Hazards!!Need for Protection! To protect Industrial, commercial, and residential Buildings withproper electrical earthingReasons:1. Lightening Damage2. Electrical leakages 3. Short circuits between phases / between phase and Neutral4. Surges in Supply lineWhy Earthing?Effective Earthing in the building protects People, Property andEquipments.
    55. 55. Result: Protection of persons within the buildingwho are occupants as owners or tenants oremployees or visitors or residentsType Of Hazards:Electric fires resulting in loss of Property and loss ofHuman lives in these divesting tragic fires. Good Earthing: ALFREDKIM chemical earthing islike an insurance for protection of property , peopleand equipments.Any compromise on quality or absence of earthingis willful act of inviting electric hazards in theinstallation
    56. 56. B. Why Electrical /Electronic fail to perform tooptimum in industry and commercial buildings.The electrical /electronic equipment e.g UPS system,Computers, cfl lamps Eapbx , ac/dc VFd ,SpeedDrives, CNC Machines, Printing Machines , Machinetools with electronic controls, Welding machines.Lifts ,EOT cranes and all such devices fitted withPCB/electronic cards have tendency to distort thesine wave of AC supply there by causing theresultant unbalanced voltage leading to HigherVoltage between Neutral and earth which lead tohigher neutral currents which sometimes are 1.73times of the phase currents
    57. 57. Hazards Prevented: Poor performance of the above equipment resulting in lossof production and loss of man hours i.e idle man hours dueto equipment failure or inefficient operation and additionalrupee expense on maintenanceMalfunctioning of equipments: Why electronic EquipmentMalfunction Specially in the IT Industry e.g. call centers,BPO`s and similar industries in particular.The electronic circuits in this equipment are operating atdifferent switching voltages as per the design of the individualmanufacturers therefore it is essential that voltages betweenneutral and earth are maintained to minimum level so that thePCB`s/electronic cards are not damaged due to highneutral currents and unbalanced voltages.
    58. 58. INSTALLATION OF ALFREDKIM CHEMICAL EARTHING b) Why watering is required for New Earth bore? When the pipe earthing /chemical earthing/maintenance free earthing/Gel earthing or whatever name it is called by various manufacturers the watering of the bore is necessary for the following reasons. a. Unlike pit earthing where the salt (Nacl) & coal is used with copper plate, the pit is dug very deep approximately 40ft to 70 ft. depending on soil conditions where the dampness/moisture is achieved at various level of depth.
    59. 59. b. In case of the modern type of earthing which is free fromfuture maintenance .The watering of the bore prior toinstallation is necessary for the following reasons.1. The depth of the bore is either 2m/3m (6ft/10ft) which ismuch less than the normal depth required in pit earthing.2. The diameter of the bore is also limited to 200/300mmagainst the pit earthing which is almost in square meters.3.Unlike salt which is used in pit earthing which dissolves inwater and salt it self becomes water in the course of timeand dries it self, thereby loosing the conductivity insurrounding of the pit. Salt itself reacts with copper &makes copper chloride & other corrosive chemicals whichcorrode the copper plates.
    60. 60. 4. The GEM used by us absorbs the water upto 13 to 15times its weight & dosen’t dissolve in the water therefore itretains its moisture property upto the lifetime of theelectrode which is more than 25 years as it contains soilfriendly materials.5. Since there is no need to recharge the pit as the GEM willremains moist through out the life, therefore it is desirableand absolutely necessary to keep watering the bore forthree to four days continuously before installing theelectrode and filling it with GEM so that the GEM will havemoist bore available with enough water soaked in the boredue to continuous watering before installation.
    61. 61. 6. After the installation no watering is necessary for futuremaintenance in whatever soil condition it has been installedeither indoor or outdoor installation.7. The earthing is quite successful in the normal climaticcondition where the average rain fall in a year may notexceed 250mm. This will give enough moisture to the soil.8. This earthing is being recommended by most of theconsultant in desert areas where there is scanty rain fall indesert areas where the water level to achieve the normaldampness is very-very deep.
    62. 62. 9. Since we are able to achieve required dampness in adepth of 2 to 3meters with continuous watering of the bore&adequate quantity of the GEM filled at the time ofearthing which remains moist for the rest of life & maintainsthe good ohmic values of earth resistance.10.To conclude the old copper pit type earthing is out ofdate & maintenance free earthing is easy to install, occupiesless space & economical in the long run.CONCLUSION:- The industry, project managers & theelectrical consultants find it very convincing to use & specifythe chemical pipe earthing which is convenient to install, nomaintenance what so ever with a long life of over 15 years.
    63. 63. c) Subject: - Location of Earthing?Question: Should it be near to the point ofapplication/Equipment or away from it?Answer: It must be near to the point of application.Reason:Please read on!1. OLD TRADITIONAL SYSTEM:- I) The conventional pit type copper plate Earthing withlarge Quantity of Charcoal & Salt was requiring largearea of about 4’x3’or 6’x4’ & depth used to be 20’ to60’(7 to 20 mtr)depending on the soil condition.II) This much area was conveniently available in thefactories/office premises in earlier days when thespace was not constraint.
    64. 64. III)The distance between the earth pit & the point ofapplication used to be few meters may be50-100mtrs & therefore to maintain the low resistance ofthe earthing wire from the earth pit to the machinery thecopper wire of 8/10 swg was used.IV) The copper wire thus used was cash & carry item forprofessional wire cutters who used to cut the wire at thefirst opportunity there by disconnecting the earthingsystem & causing an electrical danger to the system.
    65. 65. 2. PRESENT MODERN SYSTEM:- I) The space is become expensive & in short supply.II) The conventional pit type earthings is very cumbersome, laborious &occupies more space in term of sq. mtr & it is being replaced with chemicalpipe earthings.III) The advantages of pipe earthing are:-a) It needs a bore of 250-300mm dia & the depth of 2 to 3 mtr.b) It is a neat & clean installation.c) Doesn’t spoil the look of the office or factory.d) It is conveniently covered up which can be flagged showing the location ofthe earthing.e) The pipe earthing is a compact unit & can be installed very near to theequipment hardly 2-5 mtr away from the equipment.f) The closeness of the earthing has a advantage of providing very lowresistance value to the system which requires less length of the wire (ASresistance is directly proportional to the length i.e. the smaller the length,it is better for earthing)
    66. 66. g) Since the length of the earthing is required is very small in theinstallation of pipe earthings due to nearness to the equipment.h) The G.I. strip of cross section area of 10x3mm or more are used forconnecting the pipe electrode to the equipment.I) G.I. wire is not favorite of wire cutters so there are no chances ofdisconnection of wire cutting or theft.j) The copper wire of 8/10 swg which was used earlier were subjectedto more mechanical damages because of very low cross section area &the round wire is more subjected to more cross sectional damagethan the rectangular strip of 10x3 mm or aboave.CONCLUSION:- In view of above application the earthing electrodeclose to the point of application or equipment are more desirable forelectrical & electronics equipment which demand low value of ohmicresistance through out the year under all working condition i.e.extreme dry ,extremely cold or wet climates. 
    67. 67. d) Why Neutral Earthing /Grounding 1 All Neutral should have Zero Potential Difference.2. Why Neutral Voltage is Noticed Now a Days.Reasons for Neutral voltage.A. The use of electronic equipment /ups/computers /CFL lamps/Speed drives etc. These devices on operate at different cut off voltages in the  sine wave cycle and hence the sine wave is distorted resulting in the higher   PD in the Neutral and cause  the flow of currents in the Neutral Circuit which results inthe damage of PCB cards and other sensitive components in the electroniccircuit/equipmentsB) The Industrial loads are in general Not Balanced Loads and therefore the line voltages are spill over to Neutral   which results into stray currents therebydamaging the electronic equipments/ PCB cardsWhy Neutral Grounding.A. To maintain the ZERO PD between the Neutral and earth and to ground the Spill over voltages the Neutral is   grounded.
    68. 68. It is therefore very necessary to immediatelyconnect Neutral to the Earth by Solid Permanentcontact so that there is no possibility of looseconnection /disconnection at any stage OFOPERATION to prevent any electrical mishaps.Method of testing the New Earth ElectrodeA) Connect the New Electrode to the Neutral ofSupply Line by very Good secure ConnectionEither Bolted or soldered.B) Connect the Volt meter as shown in the Picture(P1) below.,C) When the Neutral is properly grounded and theearthing is Successful the voltmeter should giveNearly ZERO voltage between Earth and Neutral
    69. 69. D) Electricity finds always easier path to flow therefore the spill over voltage in the neutral will go to the newly installed earth electrode. In case earthing is not successful or has higher ohmic value of resistance or loose contact/ disconnection in the earthing circuit the voltmeter will show the undesirable voltage. In case the earthing is ok and correctly done the voltmeter will show almost Zero Volts.Kindly follow the above testing methods and ensure the testing is properly done.CONCLUTION:- The industry, project managers & theelectrical consultants find it very convincing to use & specifythe chemical pipe earthing which is convenient to install, nomaintenance what so ever with a long life of over 15 years.
    70. 70. SYSTEMS OF GRID EARTHINGReasons of Grid Earthing: -1. To manage very high fault currents So that the lowohmic value of earth resistance will reduce the effectivewatt loss thereby controlling the heat generated in thesystem.2. To maintain very low level of ohmic values of earthresistance like 0.1 etc. so that the sensitive electricalprotective devices& relays used in substations & powerhouses.
    71. 71. System at Substations/Power Houses:-1. The connected loads at your power Houses are heavy & at an extra highvoltage as well.2. The reason for maintaining the value of resistance appears to us forpreventing the malfunction of the protective devices & Relays. How can we maintain the low ohmic earth resistance:-The examples are given below:-Formula to calculate the Resistance in Parallel:-If there is n resistance connected in parallel.

    79. 79. We have given two cases for each type of grid earthing i.e. twelve earthsystems & fifteen Earth systems.Our recommendations are for fifteen earth systems to maintain a long termlow ohmic values because of the following factors:- 1. Change of a soil condition for a period of a time is choosing a differentlocation for the earthing system in the same premise.2. Change of CLIMATE CONDITION:a. Extremely dry climate- SUMMERb. Extremely cold climate- WINTERc. Extremely humid climate-RAINSCONCLUSION:- In view of above application the earthing electrodeclose to the point of application or equipment are more desirable forelectrical & electronics equipment which demand low value of ohmicresistance through out the year under all working condition i.e.extreme dry ,extremely cold or wet climates.

    83. 83. The Exceptional Nature of Graphite - Graphite - Properties The most significant property of graphite is its dimensional strength and stability at ultra-high temperatures. It resists cracking, warping, shrinking, or distortion even when temperatures exceed 2500oC. Graphite is resistant to both thermal shock and chemical attack, and can act as either a thermal conductor or insulator, depending on the application. At the same time, it is electrically conductive and naturally lubricating. Essentially inert, graphite is considered to be environmentally safe and non-toxic. While standard synthetic graphite is quite pure, extremely pure grades are available for special applications such as research and elemental analysis. It can also be processed into a variety of forms from felts and foils to composites and precisely machined components.
    84. 84. Uses of Graphite Application - Why Graphite WorksCrucibles : High purity. Excellent resistance to thermal shockand chemical attack. Non-wetting by most moltenmetals.Electrical Heating Elements : With electrical properties fallingbetween thoseof metals and ceramics, the electrical resistivity can be varied over aconsiderable range.Bushings : Self-lubrication and durability in the absence ofpetroleum-based lubricants, at temperatures to 1,200 FSintering Trays and Boats : Thermal stability, low wettability andlow specific heat.EDM Electrodes : Electrical conductivity, resistance to wear fromelectrical arcing and excellent machinability into complex shapes.
    85. 85. Molds : Dimensional stability, low wettabilityand high purity.Seal Faces : Self-lubrication, dimensional stabilityand resistance to chemical attack.Continuous Casting Dies : Dimensional stability,excellent machinabilityhigh thermal conductivity and self-lubrication.
