Figure 109: 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
110, the coordination plan shows an example of operation characteristics in the LV-side
incoming feeder and radial outgoing feeder.
