Because of transformer there is no lagging and leading current vector with reference to voltage vector. PF means the cosine value of the angle difference between voltage vector and current vector. If current vector lags the voltage vector, it is lagging, for example inductance type of loads, i.e motor. If current vector leads the voltage vector, it is leading, for example capacitance type of loads, i.e. capacitors and synchronous motors.

How do i perform grounding of star point of Genset (400V) for making connection with step up transformer of DELTA-DELTA (400V to 20KV) ? while Genset itself has its own neutral and grounding bus bar inside genset breaker box whereas we have another neutral and grounding busbar in synchronizing panel next to genset at maximum distance of 6meter, would someone pls advice if we can only perform neutral grounding in synchronizing panel or should we ground neutral on both places inside genset breaker box and synchronizing panel.
