The Delta V system has been used as an event recorder to locate difficult to find intermittent faults on underground LV feeder systems. Inherent weakness in the origin design made it difficult to use event thought it was a very useful device, this project collaborated with Kelvatek (formerly Kelman) to improve the functionality.
Delta V is a portable system for the accurate location of intermittent and permanent faults on complex Low Voltage (LV) power distribution networks. The system uses a number of small transient recorders (nodes) to record the voltage drop across the network under fault conditions and a handset to gather and analyse the fault data. The fault location is calculated using a refined version of the transgradient method and the known cable topography.
