Product introduction:

The control unit, together with our intelligent load break switch, helps isolate power line faults to avoid long-term large-scale blackouts and restore normal operation on the lines without faults, thereby economically and practically achieving distribution network automation.

The modular design control unit has highly integrated circuits and adaptive intelligent fault diagnosis algorithm, accurately detecting the fault according to the three-phase current and voltage to earth signals collected by the high-accuracy sensors. Experiential human-machine operation interfaces allows for convenient parameter set up, remote control, remote communication and instrumentation. It matches with grounded and ungrounded systems, small resistors grounding system, and arc suppression coil grounding system.

Performance Advantages

Reliable and stable operation

Goodrun’s control unit is applicable for all kinds of different severe operation conditions based on decades experience in distribution R&D and site operation. It has excellent electromagnetic compatibility performance, low power consumption, wide operating temperature range, shockproof, moisture proof, and lightning proof, with good reliability and stability.

Multi-functional protection

The control unit provides complete relay protection, control, monitoring, instrumentation and metering by local ports, and can be programmed as required. Remote communication is also available on request.

Configurable logic functions

The functional logic of the control unit is finished by the secondary configuration software configuration, which facilitates the different needs of users without modifying the underlying program.

Easy extendable system

All the software and hardware in the control unit are modularized with identical access port and extension space for longer application time in case of future extension and technology upgrade.

Easy maintenance

Big-size 5.5 inches LED screen and user-friendly navigation interface allows for local maintenance, while various communication ports for PC connection or remote connections.

Data storage

The Control unit records detailed events and data and never lose the data while the relay is de-energized thanks to the big-capacity NVM (nonvolatile memory).
