What are Phase protection relays?
Phase protection relays are devices used in electrical systems to protect against faults and abnormalities in three-phase power systems. These relays monitor the phase voltages and currents of the system and trip or isolate the system when certain predetermined conditions occur. Phase protection relays play a critical role in safeguarding electrical equipment, preventing damage, and ensuring the safety of personnel.
Some common types of phase protection relays include:
- Overcurrent relays: These relays detect when the current flowing through a phase exceeds a predetermined threshold. They are used to protect against overload conditions that could damage equipment or cause... Read More
