What does the monitoring system need to notify the operator if a fault exists?

The monitoring system needs to notify the operator of the type of fault to effectively assess the situation and take appropriate action. Understanding the specific nature of the fault—whether it's a short circuit, ground fault, overcurrent, or another issue—allows the operator to determine the next steps. Each type of fault requires different responses, and knowing the type helps in diagnosing the problem quickly and accurately.

While knowing the location, severity, and duration of the fault can also be beneficial, they are secondary to identifying the kind of fault that has occurred. For example, if an operator knows a short circuit has taken place, they can immediately prioritize measures to isolate the circuit and prevent damage or hazards. Therefore, the primary focus of the monitoring system should be on clearly identifying the type of fault present.
