Megger is used to test the resistance/insulation capacity
between two conductors be it
(*) Phase and neutral
(*) Line to ground.
(*) Phase to phase
For testing using megger

(*) Connect one terminal to the phase and other terminal to
neutral/ground for testing line to ground resistance.

(*) Connect one terminal to phase and other terminal to
another phase in case of phase to phase resistance.

All the nominal value of resistance must be greater than
atleast 1Mohm.

can transformer develop three phase poer from a single phase source?

Any one can explain if there is any harm from humming noise heard from air circuit breaker : we have 415 switch board having two incomers from transformers 3.3KV/415V , when bus coupler closed, and open one ACB incomer to work in one of the transformers, the current started hunting around 50 Amps, and heard humming noise from the air circuit breaker, although the load current was only 1200 amps while the ACB capacity is 2500 Amps, and the transformer 1600 KVA. The same didn't happen when taken the other transformer offline. Why this humming noise and current fluctuation? is there any implication or danger, bearing in mind that we just returned everything back to normal and stopped the maintenance of the transformer. Shall we go ahead and ignore this noise?
