The ZDT-300 DC Earth Fault Locator has been developed for the fast identification and location of earth faults on the DC system to ensure the damage which would occur in the event of a second fault is avoided. The system quickly and accurately finds the fault point, while overcoming the influence of the distributed capacitance of the system. It provides effective identification of high resistance faults, low resistance faults, faults creating system loops, on systems with single or multiple faults. It can also identify the presence of AC interference on the DC system.
