REC670 1MRK511313-BEN Substation busbar protection device
A busbar protection device in a Substation automation product REB670 is a device used to protect busbar equipment in a power system. Bus bar is one of the important equipment in power system, it is used to collect and distribute electric energy. When the busbar equipment fails, the busbar protection device can quickly detect the fault and take corresponding protective measures, such as cutting out the fault part or isolating the fault area, to prevent the expansion of the fault and ensure the stable operation of the power system.
The busbar protection device is usually composed of current and voltage transformers, relays, circuit breakers, etc. It can be configured and optimized according to different fault types and protection requirements, such as differential protection, overcurrent protection, ground protection, etc.
Busbar protection device plays an important role in substation automation products, it can improve the reliability and stability of power system, reduce the impact of fault on power system, and ensure the safety and reliability of power supply.
