Questions & Step-by-Step Solutions

What is the purpose of a transformer protection relay?
  • Step 1: Understand that a transformer is an important device that helps transfer electrical energy between circuits.
  • Step 2: Know that sometimes transformers can have problems or faults, like short circuits or overloads.
  • Step 3: A transformer protection relay is a device that monitors the transformer for these faults.
  • Step 4: When the relay detects a fault, it sends a signal to disconnect or isolate the transformer from the electrical system.
  • Step 5: This isolation helps prevent damage to the transformer and keeps the electrical system safe.
