A birelay is a type of protective relay used in electrical systems to monitor and control circuits by detecting abnormal conditions such as overcurrent, undervoltage, or phase imbalance. It often includes two independent relays in a single unit, enabling dual protection or control functions within one compact device. Birelays are widely used in power distribution, industrial automation, and motor protection applications. They enhance system reliability by providing timely isolation of faulty sections, preventing equipment damage and downtime. Modern birelays are available with digital displays, adjustable settings, and remote communication capabilities for easier integration and monitoring. With high sensitivity and precision, birelays support efficient fault detection and improved electrical system safety, making them an essential component in advanced electrical protection schemes.
