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.
