How to measure secondary load current of Inverter with CT clamp-on sensor
 

We’d like to measure secondary load current of an Inverter. In order to avoid stopping the factory line in service, we’d like to use clamp-on type current sensor to measure the current. We have several different types of inverters and their measurement current is each different. Let’s say some inverters’ current range are 0-150A and the others’ are 0-300A or other range. Does M-System have any suitable CT transmitters for this kind application?

MS Word

We’d like you to use our high AC current transmitter, model CTCS.

This model includes clamp-on current sensor, which you can select from wide input range from 10 up to 400A. Wide frequency band can be accepted from 4 up to 10kHz, so we think it would suitable unit for your Inverter current measuring application.
