When do you need to measure current in a transformer?
There are applications where several motors are connected to one inverter and where it is desirable to measure current in individual motors.
How does a current transformer work in a VFD?
It depends on your VFD type but most these days can 'connect' the measured current to an analogue output or use the current as a monitoring function and define internally thresholds to activate a reaction (via a relay or other switching device).
How is a current transformer used in a furnace?
One particular case, that I remember, is a furnace where several pump motors are fed from one inverter and inverter is used to set total flow rate and it was desirable to measure current of each individual motor in order to see if nozzles were clogged etc.
Can a current transformer work at 50Hz?
A traditional Current Transformer I 've used normally works in a 50HZ application. It will probably not work at the lower frequencies. An iron core can only handle a certain volt-second "area" and when frequency goes down, the area gets wider and the core will saturate.
