Figure 203: Functionality of numerical multiple-stage overcurrent protection
The coordination plan is an effective tool to study the operation of time selective
operation characteristics. All the points mentioned earlier, required to define
the overcurrent protection parameters, can be expressed simultaneously in a
coordination plan. In
Figure 204
, the coordination plan shows an example of
operation characteristics in the LV-side incoming feeder and radial outgoing feeder.
