Voltage relays

voltage detection, catenary voltage detection, threshold control, etc.

Applications and operation

These relays are used in applications such as voltage detection, catenary voltage detection, threshold control, voltage monitoring of battery chargers, etc.

In these kind of relays, the winding varies between 100 and 40000 ohms, which are fully pressurized and vacuum impregnated. These relays cover a current range from 10mV to 10 000 Volts.

These relays, associated or not to basic or specific accessories (non-linear resistors, rectifiers, transistors, zener diodes…), have led to a considerable number of very different realizations.

Moreover, the relay operation points can be made adjustable, either by the use of micrometric adjustment contacts, or by the addition of a second winding, additional or subtractive, controlled by a rheostat.

Some applications
