|i am working in automation feild my question is that how to find the KVA of transformer.
|what is the formula for 3 phase motor starting cureent
3phase 148A delta 415v, efficiancy 94%
can we run the motor with 200A incoming supply
|why the 4 terminal are named as main, line, common, voltage
(M, L, C, v) of a wattmeter??
why not its nameed as A,B,C,D??
|in india why the generating voltage is like 11kv,22kv etc
|lightning current is ac or dc..?????
|In EHV tranm. The conductors are ……..

|what percentage of marks in B-TECH is needed for section
|In power generator sets, when they are coverted from 50hz
to 60hz, the kva rating after conversion increases. For
example, the manufacturer of a perkins 200kva @ 50Hz
generator set has mentioned it to become 220kva after
converstion to 60hz. What is the relation between the
frequency & the KVA rating. Any formula please.
