why the power factor in inductive load is lagging while it
is leading in capacitive load?
Answer Posted / deepak kapil
as power factor is a cos angle between voltage ¤t.In
inductive load current lags,means the voltangle between age
and current goes upto 0 to 90 degree(we assume voltage is
constant).in capacitive load current leds, it means angle
between voltage and current comes down from 90 to 0
degree.And we know cos 90=0,and cos0=1.

When we have earthing mesh or underground earthing network in industrial plants, weather we have NT-S or NT-C-S kind of earthing system, so eventually weather we must use 4 or 5 wire in 400 volt level (For example 3×150+70 mm2 or 5×150 mm2) in this connection I would like to know exactly the paragraph of IEC or IEEE number
