The ZDT-300 DC Earth Fault Locator is used to quickly and accurately locate DC network earth faults on live systems. It consists of a signal transmitter, receiver and a choice of sensors for different cable sizes. Depending on the model chosen, the system is capable of detecting high resistance faults up to 1MΩ, allowing problems to be identified at an early stage, so that remedial action can be taken to prevent a subsequent failure.
