TTE 7017 Relay

TTE   7015 / 7017

Rotor earth fault relay STATIC RANGE

The object of the TTE 7015 and TTE 7017 is to detect immediately any fault on the rotor winding of a synchronous machine, in order to give an alarm and, if required, to separate the machine from the network.
They operate on the current injection principle, d.c. for the TTE 7015 and low frequency a.c., with low levels of voltage and current (maximum 20 V or 5 mA) for the TTE 7017.

Both models are supplied in a modular plug-in case type R2, which may be mounted either as a separate relay, projecting or flush mounting, or as an element in a standard 19" rack cradle.
