Electricity is the general term encompassing a varietyof phenomenon resulting from the presence and flowof electric chargeThe word originates from the Latin, meaning "amber-like”, here amber (hardened plant resin) becauseelectrical effects were produced classically by rubbingamber
ELECTRICITY GENERATION is the first process in the delivery of electricity to consumers. ELECTRICITY GENERATION is the process of generating electric energy from other forms of energy. British scientist Michael Faraday said that electricity is generated by the movement of a loop of wire, or disc of copper between the poles of a magnet.
ELECTRICITY POWER TRANSMISSION is the bulk transfer of electrical energy, from generating power plants to substations located near population centers Transfer of electrical power from Generating Stations to the industrial, commercial or residential consumers is as important as power generation. Transmission lines, when interconnected with each other, become high-voltage transmission networks. These are also known as "power grids" or just "the grid".
ELECTRICITY DISTRIBUTION is the final stage in the delivery of electricity to end users. A distribution systems network carries electricity from the transmission system and delivers it to consumers. The network includes medium-voltage (less than 50 kV) power lines, substations and pole-mounted transformers, low-voltage (less than 1 kV) distribution wiring
Major threats with1.Open Street boxes2.Open Street lamps3.Open Live electrical cables4.Absence of control boxes on street lamps5.Poor maintenance6.Cables lying on the footpaths7.Frequent expose to sun and rain can lead to its wear and tear8.Electricity easily accessibale leading to electricity theft
The street boxes in campus of MSEDCL was maintained properly which is ideal way of maintaining the street boxes
OUR VIEW The interview conducted following views were generated regarding the maintenance practices adopted by the MSEDCL. During our interaction we took a look at the complaint form which had variouscommon problems faced by the costumers listed one by one. But an option to complaint regardingthe poor electrical safety in public places was missing.The Executive Engineer told us about the various safety gears the electricians use. However when weasked the electricians to show these gears and tools, only the rubber gloves were shown. This raised aquestion in our mind whether they are equipped with all such gears and tools. The answer we got for locking of the street boxes shows negligence of the officials. Most of the street boxes were found without locks. The doors of the street boxes were tied temporarily using ropes. Thus, there was much scope for improvement in the practices adopted by the MSEDCL.

Safety can be defined as the control of recognized hazards to achieve an acceptable level of risk. Safety precautions need to be taken at every stage. Should be documented in the form of Dos and Don’ts. Warning signs must be displayed.
Serious injuries, deaths, and property damage occur daily. Over 1000 electrical workers die each year from workplace accidents. 97% of all electricians have been shocked or injured on the job. Electrocutions are the 4th leading cause of traumatic occupational fatalities.
Electric field is invisible and silent. Persons touching non-effectively earthed, faulted metal parts in electrical installations are exposed. Persons working in substation, power stations, transmission lines, cables etc are exposed. Persons who are unaware of presence of electrical power.
Enforcement of safety rules and acts. Electrical Safety Rules are to be made mandatory. Psychological approach Awareness of safety is created. Placing large signboards, displaying drawings, DO’S and DON’TS. E.g. Short circuits can be handled by automatic protection system.
Handling of electric supply lines and apparatus: ◦ Provided with tools and devices such as gloves, rubber shoes, safety belts, ladders , earthing devices, helmets. ◦ Every telecommunication line on supports carrying a high or extra-high voltage line shall, for the purpose of working thereon, be deemed to be a high voltage line.
Street boxes: ◦ Street boxes shall not contain gas pipes, and precautions shall be taken to prevent. ◦ All street boxes shall be regularly inspected for the purpose of detecting the presence of gas. ◦ The owners of all street boxes or pillars containing circuits or apparatus shall ensure that their covers and doors are so provided that they can be opened only by means of a key or a special appliance
