Arcteq’s AQ-50 fault detection devices leave no fault unnoticed! With their superior capability to detect even the most challenging faults like high-impedance and intermittent earth faults, AQ-50 devices deliver accuracy users can rely on. AQ-50 devices analyze changes in phase currents during an earth fault and detect faults as low as 0.5 A.
No separate voltage measurements are required which also saves space and significantly reduces cost. AQ-50 devices are applicable for any type of distribution network in new and retrofit installations. It also enables automating the entire distribution network, including service restoration (FLISR*), without any additional equipment.
