Description
The AQ-50-XXXX1 fault detection device for one (1) feeder leaves no fault in distribution networks unnoticed. It has a superior capability to detect even the most challenging faults, such as high-impedance and intermittent earth faults with a fault current as low as 0.5 A; this allows it to deliver a fault detection accuracy you can rely on.
The AQ-50 fault detection is based only on phase current measurements. This saves space and significantly reduces costs as there is no need for separate voltage measurements. All this makes AQ-50 devices easy to fit in both new and retrofit installations. The AQ-50 devices are applicable to any type of cable or overhead line distribution network whether they are compensated, isolated, or directly earthed.
