RTU

Remote Terminal Unit

Our Remote Terminal Unit is LBS (Load Break Switch) and ACR (Automatic circuit recloser ) microprocessor controller.

Control cubicle is heat insulated to minimize temperature variation and protected controller from solar heating as adopting sunshine cover to the outside and heat insulation inside of control cubicle. Vents of the control cubicle are screened against vermin’s entry and door is sealed with a gasket.

Our microprocessor controller are fully protected from entry of moisture and condensation able to use any places where tropical, moderate and severe humidity area is located on.All the measured values and event records are stored in the microprocessor control for Sending data to SCADA system or off-line checking maintenance and analysis. All telemetry communication can be supported with DNP3.0, MODBUS, IEC60870-5-101/104 communication protocols

Sensitive sensors provide to incorporate the functions of an over-current protection relay, a ground fault relay, a sensitive earth fault relay and to measure line current, voltage amount, real and reactive power, power factor, demand watts and VARs, frequency and so on.

Recloser mechanical parts are drastically reduced, resulting from high reliability and maintenance free operation during the life time. We use low-voltage power source supplying from low voltage distribution line by Solar Panel or PT and a fully charged battery and trip and close capacitors provide Recloser operation over hundreds of open-close operations as back-up upon loss of control Power. This allows Recloser operation independent of the high voltage supply, the low voltage supply and the battery and capacitor conditions with dead line operation capability required for SCADA and distribution Automation.
