We provide protection control systems to prevent large-scale blackouts. In these systems, protection relays to instantaneously detect abnormalities in power systems or equipment (system faults) and send out commands to cut off the faulty section are used to prevent the fault from spreading or to minimize the impact.
In recent years, we have developed highly-functional, high-performance and highly-reliable digital protection relays taking advantage of advancement in micro processors, contributing to the stable and safe supply of electricity.
