POWER FACTOR CONTROL RELAYS
Fully automatic microprocessor based and easy commissioning, this Power Factor Control Relays are offered in a variety of PQC/PFC controlers. The range of relays has patented control attributes along with over current trip function and protection for the capacitors. Through self-alteration of control program, the relay four quadrant regulations, constantly monitors defective capacitor phases. These controls relay has automatic and manual function with capability to switch every individual capacitor stage ON or OFF. This shows zero current and zero voltage tripping with alarm indication.
