How can transformer oil be used in transformers with voltage
rating above its breakdown voltage?

Answer Posted / durga rao .n

in transformers oil be used for insulation purpose between
core and body, reducing winding temperatures. main thing
protecting for the transformer from un-balanced loads,
internal short circuits and winding temperatures. it's should
be have minimum break down voltage is 50KV.

Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
