Questions & Step-by-Step Solutions

What is the primary function of protective relays in power systems?
  • Step 1: Understand that a power system is made up of various components like generators, transformers, and transmission lines.
  • Step 2: Know that sometimes these components can have problems, called faults, which can cause damage or safety issues.
  • Step 3: Learn that protective relays are special devices used in power systems.
  • Step 4: Recognize that the main job of protective relays is to detect these faults when they happen.
  • Step 5: Understand that once a fault is detected, the protective relays help to isolate or disconnect the affected part of the system.
  • Step 6: Realize that this isolation helps to prevent further damage to the power system and keeps people safe.
