Answer Posted / khadu ali murthuja
Transformer rating already given=2000KVA
Select Air circuit breaker ie secondary current multiplying with 1.6A to the rating of the transformer.
secondary current = 2000×1.6
= 3200A Air Curcuit Breaker Required.
since 1KVA =1.6A
how to find out primary current.
the relation ship between voltage and current.
V2/V1=I1/I2
415/11000=I1/3200
I1=120A...

1. for eg, capacitor is used for many purposes(it act as filter, oscillator, bypass capacitor, memory storage etc...) 2. Please tell me some example circuits for different uses of capacitor( whenever and whereever and however we used capacitor as a filter, oscillator tuning etc..) 3. similarly for inductor and resistors(it act as what?) and when and how we want to act as like that?, and how we can used these components depends upon our requirments with example circuits and explanation? design to act as these components depends
I have 2500KVA transformer delta/star,13.8KV/380V provided with LV 4000A breaker. Already I have 2300KW motor feeder with a full load 90%. Is it possible to connect another 1600A from that breaker? If so how the calculation is done?
