how will be power factor while using the resistive load and
Capacitive load?
Answer Posted / paul
yes in a resistive load the PF is about unity.
but in a capacitive load the PF is leading but that depends on the size of the capacitive load.
This can be calculated using "J" notations to give the final impedance, phase angle and then current been consumed by using ohms law

Please clarify, 1. Is it required to lay two runs of GI wire along with Armoured LT cable if it is laid between one big mains (63Amps TPN SDF) to small main (32A TPN SDF) with proper glanding termination? 2. If the armoured cable with proper glanding is laid from DB to CNC machine, is it required to run two runs of body earthing to the Machine from DB? 3.If the armoured cable with proper glanding is laid from Substation to Hangar, distance is approx. 100 mtrs, is it required to do earthing at shop area though the primary termination at substation is earthed through gland.
