9.2.5 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 52-TOC, 29DS and 29GS functions covers remote and local status
indication of, for example, disconnectors, air-break switches and grounding switches,
which represent the lowest level of power switching devices without short-circuit
breaking capability.
