How to Locate HV Cables with a CAT & Genny — Techniques, Challenges & Best Practice

Locating high voltage (HV) cables safely and accurately is one of the most critical skills in utility detection. In this video, Sygma Solutions trainer Peter Ashcroft walks through the techniques and challenges of finding buried HV cables using a CAT and Genny — the cable avoidance and signal generation tools used across the UK utility and civil engineering industry. What you'll learn: • Why HV cables can be harder to locate than they should be • How to apply a transmitter signal to a known HV cable for positive identification • Power Mode vs Radio Mode vs Genny Mode — when each works (and when each fails) • Common HV cable strike patterns and what causes them • What to do when drawings show an HV cable but you can't get a clean signal — the case for STOP This video supports Sygma's wider work on utility damage prevention, including the analytics-driven CAT data review programme and Sygma's strategic training partnership with the Clancy Group.
