Answer Posted / macharia
reactive power is wattless power (without energy flow)
caused by reactive loads: capacitive and inductive
(induction motors, solenoid valves, transformers) loads. It
is measured in var - volt-amps-reactive. capacitors release
while inductors use the reactive power. reactive power
causes increase in current in transmission lines and hence
large voltage drop. this may require oversizing of
transmission lines.
capacitors can be installed to cancel the reactive power
from inductance of 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.
