how to select the rating of neutral ct with reference to transformer secondary current(in power transformer,stepdown tansformer,for example2000kva,11kv/415volt
2 7015What, in the construction of a transformer, controls KVA? For example 600/208/120 V transformer can be 10kVA or 45kVA!!! What do we change in the construction of a Transformer in order to change the rating but not the voltage.
