Application

In the field of distribution and sub-transmission automation, the reliable control and
status indication of primary switching components both locally and remotely is in a
significant role. These features are needed especially in modern remote controlled
substations. The application area of DCSXSWI and ESSXSWI functions covers
remote and local status indication of, for example, disconnectors, air-break switches
and earthing switches, which represent the lowest level of power switching devices
without short-circuit breaking capability.
