Monitoring Relays
What are Monitoring Relays?
Monitoring relays are electrical devices that are used to monitor various parameters in a power system, such as voltage, current, temperature, and frequency, and trigger an alarm or action if the values go beyond a preset threshold. They are designed to detect abnormal operating conditions in a system and alert operators or take corrective action to pre...
