FAQ
Q: What are the basic types of protective relay?
A: Protective relays come in three fundamental types:
1. Electromagnetic Relays: Utilizing armature, induction cup, or disc mechanisms.
2. Static Relays: Employing solid-state devices to process analog signals.
3. Digital/Numerical Relays: Leveraging programmable solid-state devices for digital signal processing.
Q: Why is relay testing important?
A: Relay testing is crucial to ensure the effective operation of relays in response to faults. Regular testing prevents electrical system risks, equipment damage, and harm to personnel. It verifies the reliability of relays, maintaining a well-protected system.
Q: How do relays detect faults?
A: Relays monitor small deviations in current, voltage, resistance, or temperature. When these signal a fault, the protective relay takes corrective action, such as tripping a circuit breaker, to prevent electrical system damage.
