Sir, that's a very good video, but I wish to know , how to select the applied voltage for single and 3 phase conductors. Is it that the the voltage applied must be twice the RMS value of nominal operatinal voltage??? Kindly reply
Test voltages are taken from the regs and are dependant on the circuit to be tested rather than RMS of supply. As a rule in domestic application and on standard circuits on 3 phase, that value is 500V. However to ensure you are testing IR appropriately for each circuit reference should be made to BS7671.
sorry to be off topic but does someone know of a way to log back into an Instagram account..? I somehow forgot the login password. I would appreciate any assistance you can offer me!

Thankyou sir ,wonderful

Selv-pelv systems= 250v 0.5ohms
Up to 500v systems = 500v 1.0ohms
Above 500v systems =1000v 1.0ohms

Breakers off? Shouldn’t they be left on
Why? You’re testing out the top of the breaker so makes no difference if the breakers are off
