Answer / sheik farvat

one end of capacitor wire is connected to phase and another of the capacitor wire is connected to the neutral,then remove from the socket and touch the capacitor two wire (phase and neutral )if spark is coming is good or otherwise is bad

Answer / harishdarade563

Firstly check out the rating of capacitor you want to check.According to voltage rating given on capacitor, apply the voltage to its two terminals(Note :Do not apply the voltage more than rating voltage,otherwise it will make a short circuit,less voltage can be applied) and then short those terminals.if spark between terminals is observed it is good otherwise it is bad.

Answer / k.prakashchandra

Do not give supply directly but through a bulb. It may be shorted or you may exceed the rated voltage . If the capacitor is good the brightness will be less and you can also test for stored energy

I find that underground strip-armoiured,4core,LT PVC cables in an earthed power distribution sytem are occasionly found in charred condition-with no trace of it except ash. Is this because of no proper earth connection/continuity (giving rising to high armour resistance)in the joint enroute or because of insufficient capability (again due to high armour resistance)of cable-armour to carry fault current or due to neglected /unprotected overloading of the cable or due to high armour currents caused by power thefts where only phase(s) are unauthorisely tapped & at the point of poer consumption earth terminal is established by burring underground a not so good earthing rod (or using an underground water pipe for the purpose)
