Protection relays have different functions. They are often made up of several modules, each of which performs a specific function. In this guide, we will distinguish three types of functions: protection against abnormal variations in the main supply, protection against leakage currents, and protection against overloads.
Protection against abnormal grid variations
Abnormal voltage, current, and frequency variations can lead to problematic phenomena. These...
