Thytronic presents The relay SVR

The relay type SVR is intended for the protection of electric lines and machines against voltage variations.

The relay SVR features the following principal characteristics:

three-phase measuring circuit for the line voltage, with star or delta connection;

measuring circuit, provided with a band pass filter, for the residual voltage;

protection functions and final relays completely programmable by the user;

direct read-out of all the input quantities by means of digital display on the front panel;

counting the number of operations for each function;

storing the values of input quantities corresponding to the last operation;

optional digital input circuit, to perform adaptive protection schemes;

serial communication circuit;

continuous monitoring of internal circuits.
