How we helped
- Developed and evaluated the relay settings for substation equipment at 34.5 kV, 46 kV, 115 kV, 138 kV, 230 kV, and 500 kV including settings for breaker failure, bus differential, transmission line and transformer relays.
- The breaker failure relays developed include SEL-501 and SEL-451.
- The bus differential relays developed include SEL-487B and SEL-587Z.
- The transmission line relays developed include SEL-411L and SEL-421.
- The transformer relays developed include SEL-587, SEL-487E, SEL-421 and SEL-551.
- For assisting in communication schemes implemented over PLC on transmission lines, UPLC-II and PCM-5330 were configured.
- Relay setting reports were created for all the developed settings.
- Developed relay settings were coordinated and associated TCC curves, mho plots and CTI references were provided for documentation.
- End-to-End (E2E) test files were created for applicable relays.
