Improved generator circuit breaker enhances power plant protection

摘要

A generator circuit breaker (GCB) plays a vital role in power plants: It protects key equipment and increases plant availability. ABB's successor to the HEC 7/8 – the HEC 10 GCB – offers additional benefits, eg, improved switching capability, lower SF6 volume and leakage rate, extended lifetime and a smaller footprint →1.
