Description:

Process Bus relays have been used for many years in trials all over the world. In most applications the focus has been to prove the concept of using sample values instead of instrument transformer secondaries to protect the power system. In most cases these trials were performed at small substa-tions or on individual feeders. The trials were suc-cessful at proving the concept, however, the gen-eral use of this technology has been limited due to the practical requirements of real installations. This paper looks at some of the challenges intro-duced by breaker and a half substations and looks at methods available to allow process bus relays to be applied in a practical way.
