Answer / hihi

open delta system or the v-v connection is used to minimise costs as it is a bank of 2 1-phase transformers can b used for the power supply purpose ..but its poweer output is 57% of the 3 ph transformer .. used wen less load cond so d losses r less ...and wen in fftute load requiremnt increases the 3rd windin is added

In power point wiring,often,we use less size of earth wire compared to phase & neutral wire and we use big size pin in pug top. how is it justified? can we use small size cable for earthing?
