while measuring insulation resistance using Megger at first it shows some what lesser value of IR and then it comes to a steady value some higher value than the initial. why?
elpee:-If the motor connected in star &applied full rated voltage,we know that two windings(phases) are connected in series between two phases. Incase of delta each winding is connected between two phases.
That's why the current passes through star connetion is less (i.e 1/3) as...
