The relay protection industry has shifted from traditional electromechanical systems to digital relays, supported by advanced testing equipment like the three-phase relay test set. Digital relays are computer-based devices that utilize digital signal processing techniques to measure, analyze, and actuate protective functions in electrical power systems. Find your protection device by selecting the required application. You will get a list of all suitable products! Future-proof your power supply with protection relays and control for digital. In utility and industrial electric power transmission and distribution systems, a numerical relay is a computer-based system with software-based protection algorithms for the detection of electrical faults. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions.
