What is a Meter relay?

A meter relay is a protective device used to monitor the status of electrical equipment and systems, tracking parameters such as power flow, voltage, and current fluctuations. This relay functions by providing alerts or automatically disconnecting equipment when abnormal conditions exceed preset thresholds, ensuring the protection and safety of the equipment. For example, it can detect abnormalities like overcurrent, overvoltage, or undervoltage, and act accordingly to safeguard electrical equipment and circuits. Meter relays are often used in large-scale facilities such as power plants and substations, playing a crucial role in preventing faults and accidents.

Application of Meter relay

✅Power plants
Used in power plants to monitor overcurrent and overvoltage, ensuring equipment protection.
✅Substations
Used in substation power equipment to monitor voltage and frequency fluctuations, disconnecting power when issues are detected.
✅Commercial buildings
Used in large commercial buildings to monitor electricity supply and prevent equipment malfunctions.
