It provides all-round protection against overcurrent, ground faults and overvoltage for distribution feeders. The zero-sequence current detection function accurately identifies ground faults, and the adjustable overvoltage pickup level allows customization for different power grid operating conditions. It quickly triggers protective actions when faults occur to minimize damage to feeders and related equipment.
Beyond its primary role in feeder protection, it also acts as backup protection for power transmission lines, buses and transformers. This dual protection design enhances the overall fault tolerance of the power distribution system and avoids widespread power outages caused by single-component failure.
It incorporates two security features to prevent unauthorized configuration modifications. A hardware jumper is required for keypad editing of setpoints, and an eight-character alphanumeric passcode is mandatory for both keypad and software-based setpoint editing. The enhanced faceplate and intuitive interface allow users to view real-time parameter values through the actual value window, simplifying operational monitoring and configuration.
It supports multiple communication methods such as Ethernet, serial and fiber optic connections. It can seamlessly integrate with upper-level industrial control systems and monitoring platforms, realizing centralized management of multiple relays. It enables remote retrieval of operational data and adjustment of setpoints, improving the intelligence and management efficiency of the power distribution system.
It is widely deployed in urban and rural medium-voltage power distribution networks, especially in key feeder lines connecting residential areas and commercial districts. It quickly handles faults such as short circuits and overcurrents to avoid large-scale power outages and ensures stable power supply for residents and businesses.
It is applied to the power distribution feeders of petrochemical production plants, including feeders for reactor auxiliary equipment, pipeline pumps and heating systems. It resists the harsh on-site environment and prevents power supply interruptions caused by electrical faults, which could lead to production halts or safety accidents in flammable and explosive petrochemical settings.
It protects the distribution feeders of high-power equipment in metallurgical plants, such as blast furnaces, crushers and continuous casting machines. These devices have large load fluctuations during operation, and the relay’s precise protection and real-time monitoring functions stabilize the power supply, ensuring the continuity of smelting and processing processes.
It is installed in the power distribution systems of automobile manufacturing, machinery processing and other large workshops. It manages the feeders powering production lines, robotic arms and precision testing equipment. It reduces production downtime caused by electrical faults and improves the operational efficiency of the production workshops while protecting expensive production equipment from damage due to electrical anomalies.
It is used in the power distribution systems of large shopping malls, high-rise buildings, hospitals and data centers. It safeguards the feeders supplying power to air conditioning systems, elevators and server clusters. It ensures uninterrupted power supply for critical facilities and maintains the normal operation of public services and commercial activities.
