Characteristics of relay protection for substations
This comprehensive article delves into the key aspects of relay protection in HV/MV substations, including calculations, settings, coordination, selection, and validation, which are all critical to achieving high levels of system reliability and safety. In HV (High Voltage) and MV (Medium Voltage) substations, relay protection safeguards critical assets such as transformers, circuit breakers, and lines. Common relay types include overcurrent, distance, differential, earth fault, and digital relays. The increasing sophistication of protection schemes coupled with the advancement of technology and the desire for vendor interoperability has resulted in. Numerical relays are based on the use of ...
