Product Overview
The Oryona Cable Fault Locator – Underground Series is an advanced field diagnostic system engineered for rapid, precise and verifiable fault identification in buried MV/LV power cables.
Combining TDR reflection, surge/thump energy, acoustic pinpointing, and electromagnetic tracing, it drastically reduces excavation time and fault uncertainty.
Ideal for utilities, EPC maintenance teams, and industrial networks with buried feeders
