Dear All, i would like to ask how to know the breakdown voltage value of enamelled single daglass covered copper strip?can i use baker hipot test for this? thank you, regards, Marten

Dear All, if i have data for a motor : number of coil ,turn/coil,pitch,AGD,CMA,stator core length,core diameter, connection,slots, wire size, is it possible for me to calculate the weight of copper for the wire from those data?by the way this is for low voltage motor thank you, regards, Marten

hi everyone, i have a motor 3 kv 125 kw, the motor was place in a room and the room accidently was on fire. after the fire, we have checked for the winding insullation resistance and the result was 2500 MegOhm, my question is what next step do i must do next to ensure the motor is still ok to...

hi every one, i need help on my transformer, we have measured the value winding insullation resistance of secondary-ground of our transformator and the value was 0.1 MegOhm, the transformator is 1600 KVA, primer 20 KV to secunder 400 Volt, my question is , is it possible to have 0.1 MegOhm...
