Instrument transformers (ITs) are key components in the application of relays, meters and bay computers to protect, measure and control the operation of power networks.
Redundancy means to provide transparent “backup”. In modern digital substations this is an important requirement for Ethernet communication as downtime cannot be tolerated, even in the event of a switch or fibre cable failure.
IEC 61850 is the new international standard of communications for substations. It enables integration of all protection, control, measurement and monitoring functions within a substation and provides the means for high-speed substation protection applications, interlocking and intertripping.
