Test interfaces for protective relays

Test interface for relay protection and automation equipment
Regular checks in high- and medium-voltage switching systems made simple
Overloads, ground faults and short circuits in high- and medium-voltage switching systems of power generator, transmission and distribution grid operators or in industrial use are detected by the installation of suitable protective equipment and tripped by circuit breakers. This protective equipment must be tested at regular intervals in order to detect and avoid any possible outages. To this end, our WIPRO test interface decouples the protective side from the mains side, thus enabling safe and simple testing and setting of the protective relays during operation.
