In Transformer testing at Shop test we normally test for
vector group, open ckt.,short ckt. but what are the other
test performed for transformer once it reaches at site.For
e.g:if the transformer is dry having rating 1000KVA?
If the capacity of water Tank is 50000 Liters situated at 20
meters height from ground level,What would be the size of
pipe and how much USGPH water will be supplied and what will
be the motor or pump rating used for this work?Illustrate by
1)How much current can a 3-1/2 core 100 mm wire carry?
2)What are the special cables required for explosion proof wiring?
3)In case you do not have coal and salt for earthing, how can you achieve good temporary earthing?
4)One horse power single phase motor is more likely to get hot than a one horse power 3 phase motor. Is it true or false, if true why?
5)What are the different types of soft starters for large motors?please explain?
