diffrential protection use for protecting of transformer
internal fault

Answer / thaker harit

transformer differential protection is that when the earth fault current is higher so that h.v side and l.v side transformation ratio must be maintain but that time the ratio could not be maintain that time transformer will be tripped in differential.

Answer / m.w.

Differential protection compares de primary currents with secondary currents (which must keep the same ratio) in order to detect a "differential" current between them caused for an inner fault.

for 100 HP Induction motor service factor is 1.2(SF) we placed a VFD at the motor side load is balance with 0.3 Amp's Phase to Phase but at incoming of VFD load is un-balance with 10 to 20 Amp's what will be cause of load un balance
