Power Factor Control Relay BLR-CM 3 Phase
Reactive compensation plays a vital part in reducing losses in cables, transformers etc thus reducing CO2 levels. Today’s microprocessor technology allows power factor control relays to accomplish far more functions than ever before. The CM 3 phase relay combines a 3 phase power factor control regulator with a 3 phase multi meter – thus saving switchboard panel space and panel wiring time. Each phase is monitored independently by means of a CT on L1-L2-L3. In this way single phase capacitors can be switched so as to balance asymmetrical loads. The optimal size of capacitor is always selected when using the CM3. Each kvar step value is held in the memory and called upon when required. The CM3 has a complete programmable alarm system as detailed in the heading “supervision” below. If there is a failure of capacitors, contactors or fuses, the alarm will operate and the LCD display will indicate the cause of the alarm. A MODBUS RTU card can be fitted – RS485 and data logging can be undertaken using our MINISCADA which can be connected to the internet by modem/GSM.
