High Voltage Design and Installations Master ClassLiving Online
This course is aimed at the private electrical installation designer. However, the topic HV design and installation could also be interpreted as possibly covering the electricity utility transmission and distribution sector (HV transmission and distribution network design) for which the HV design approach would be quite different, even though the technical fundamentals (and some of the technical standards such as AS 2067) are the same. This will not be the focus of this presentation.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

2. • Introduction
• Test equipment provided in high voltage lab
• Activity and study in high voltage lab
• Classification of high voltage lab
• Clearance of high voltage Lab
• Layout of high voltage lab
• Safety
• Shielding of the high voltage lab
CONTENT
3. Introduction
• In this industrial developing world the need of power is increasing exponentially
thus to transfer high power at long distance is necessary.
• So the transmission at h.v is possible which is up to 720 kv and 1000kv.
• So extensively study is made on high voltage d.c. testing at 400 kv .
• Thus to perform tests and research the lab providing high voltage is needed.
4. • Transformers
• Lighting arrester
• Isolator and C.B
• Different type of insulators
• Cables
• Capacitors
• Line hardware and accessories
• Other equipment like reactors
Test equipment provided in high voltage lab
5. Activities and studies in high voltage laboratory
• Main is testing on equipment
• Other than it is research
• So research include
i. Breakdown strength of different material like
solid ,liquid and gas.
ii.Electrical interference of transmission line.
iii.High voltage power system’s insulation.
iv.High current phenomena such as electrics arc and plasma physics.
9. Withstand Voltages, Test Voltages and the Rating
of Equipment in High Voltage Lab
• Generally up to 230 KV design it does not pose any problem but above
400 KV it is to be handle with care.
• For research and development work, the voltage levels needed are usually
about 1.3 times the maximum test voltage needed. Hence, the laboratories
intended for different system voltages should have the test voltages
10.
11. Size and Dimensions of the Equipment In High Voltage lab
• Mainly two type of lab:
1. indoor type & 2.outdoor type
• indoor type has the advantage of
1. protection of testing equipment against variable weather conditions,
2. simplicity in design and control of the test equipment,
3. provision of observation facilities during testing.
• outdoor laboratories have the advantage of
1. less cost due to the absence of building cost and
2. the planned facility
3. layout cost
• But it has disadvantages
1. absence of lifting and supporting facilities,
2.reproducibility of results not being guaranteed due to uncontrolled
atmospheric conditions, and
3.artificial and wet test studies which are difficult due to wind variation, etc.
12. • When high voltage laboratories are planned as indoor
laboratories, the following figures fix the dimensions of the
laboratories:
1. Size of the test equipment for a.c., d.c., or impulse generators.
2. Distances or clearances between the test object and ground
during test conditions and also between all the high voltage
terminals and earthed or grounded surroundings such as walls,
roofs of buildings, and other test equipment not energized.
13. Clearance of HV Lab
a) For power frequency test
b) Lightning impulse clearance
c) D.C. Generator clearance
14. a) For power frequency test
• The 50% flashover voltage is expressed as,
• V50%=652 × d0.576
where, d –air-gap distance,
• For example,
1)For 1000 kV(rms) – d=3.835 m
2)For 1500 kV - d=7.754 m
3)For 2000 kV d=12.8 m
15. b) Lightning impulse clearance
• Generally a clearance of 2 meters for each 1000 kV is necessary for lightning
impulse generator. Impulse flashover voltage is given by,
• V50= 500 × d for a rod plane gap.
• The withstand voltage can be assumed to be 80% of V50.
• It means, 2 meters gap will withstand 800kV(peak).
• For d.c. generators, a clearance of 4 meters for every 1000kV is recommended.
c) D.C. Generator clearance
16. Layout of high voltage lab
• Laboratory arrangements differ very much from a single
equipment to multiple d.c., a.c., & impulse arrangements in
different testing program.
• It is based on type of equipment to be tested, available space,
other accessories needed for the tests……
• EARTHING, SAFETY and CONTROL GEAR is foremost
consideration ……
18. Shielding of the high voltage lab
• Safety is one of the most important requirements in a high voltage lab ,
• Proper operation of the high voltage lab include the presence of qualified
personnel,
• The use of systematic procedures, safety ropes, signs, visual and audible
warning & alarms, the use of grounding rods, the periodic review of safety
rules, the availability of fire extinguishers, emergency phone numbers, first aid
kit, and smoke alarm system.
• The walls, two supporting pillars and ceiling of the HV Lab require shielding
with a system of interconnected modular steel sheet elements mounted on
wood framework.
