Differential relays

DC or AC current differential protection, AC or DC voltage differential protection, etc.

Applications and operation

These relays are used in applications such as DC or AC current differential protection, AC or DC voltage differential protection, etc.

In this kind of relays, the winding is composed, either of two or several straight bars going inside the magnetic circuit, or of big coiled wire.
