what will happen if the secondary of current transformer
kept open....
Answer Posted / hareesh
it is normally a step up transformer,high voltage will
induse in secondery since there is no opposing flux for
primery.it is normally used for measuring purpose no current
will flows through it.flux will saturate.

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.
Why in metering Ct for ammeters ct secondary side is grounded for each Ct but not in case of CBCT (Core balance current transformer)..kindly some1 highlights the reason..is it because net flux is zero?
