This microprocessor-controlled relay is capable of switching 50-amp single phase AC loads at up to 660VAC, when controlled by a 4-32VDC signal. Its internal current sensing circuitry monitors and ...

The occurrence of current sensing errors in relays is caused by several factors such as CT saturation, the wrong position of the core wiring on the CT, and the double grounded secondary connection.

When tasked with a current sensing requirement, designers typically look first to using dedicated resistors designed for this task. Occasionally though there is the temptation to consider sensing ...

After tolerating the extra noise and expense of operating the converter in this manner, I devised a solution that involves a current-sensing relay. I install a commercially available current-sensing ...
