1,Building containing 25 flats how much Amp 3 pole MCCB are required?
2, For the safey of each flat how many Amp RCCB can install -loaded with A/C
in 3 phase (4 wire) star connection - is current pass through neutral??
When we are working on transformer(132\11KV). we are going to isolate the transformer from both HV side and LV side. then we are applying grounding on both side. My question is that we required to isolate the VT which is still connected from secondary side.?

Whai isPCC and MCC Difference?
Why ferranti effect occurred in leading p.f load?
