Answer Posted / saravanan.p
A graph drawn between voltage(V) and Current(I), a curve
will form due to loss between voltage and current. This is
called power factor.
This is also defind as the ratio between Apparent power to
Actual power.
Power Factor = KW / KVA.

What is critical disruptive voltage?
y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
at meter room 50 hrc switch installed,but there are not get earthing proper,so what happen?and 11kv transformer out put going in to hrc main 400a three nog each? so earthing is require for all switch? (some customer made earthing at there home.)
How to calculate per unit impedance of transformer?
Hi everyone. Some Generators uses 3-Pole breakers with extra contactors for Neutral. Some uses 4-Pole. Why so? What is the idea behind this? Thanks in advance for the solution. Kr.
Its possible to use 3core 2R of 240 sq.mm cable for 3phases & separely 50sq.mm 3core cable fully for Neutral for connection of PCC to MCC 3ph..4wire system?
