ERLPhase Power Technologies has announced IEC 61850 protocol certification of its L-PRO 4000 transmission line protection relay. Issued by the Central Power Research Institute of India, this assessment is based on the UCA International Users Group Device Test Procedures. ERLPhase will offer the IEC 61850 Station Bus protocol (8-1) as a standard feature on its 4000 Series relays and recorders, being released later this year. ERLPhase says the standard was developed to ensure interoperability of substation automation devices.
