Abstract :
The paper describes the installation and operating results of a bus protective scheme, which uses a combination of high-speed directional ground relays on all sources of fault current and high-speed plunger type blocking relays on all outgoing circuits. The scheme described is independent of the ratios and characteristics of the current transformers.
