Protective Relaying (Power Line Monitoring)
Reliability and accuracy are crucial in electrical transmission and distribution systems, protective relays enable them to remain uncompromised even in the harshest environmental conditions. Protective relays are critical components of the electrical grid, clearing faults and protecting equipment from failures. Analog Devices has a suite of leading-edge products tailor-made for the challenges faced by protective relays that enable flexible, reliable solutions from MV to HV.
