Electrical Cable Identification

Technology Overview

A non-clamping method and apparatus for active identification of dead underground power utility cable.

It solves the following problems when doing utility power cable identification using signal magnitude principle in congested area:
1) EM interference from adjacent loaded cables
2) Acoustic interference from road side noise
3) Spatial resolution when adjacent cables are too near to each other
4) Provide non-clamping method to cover its blind spots using different principle

Who is going to buy this technology?
Equipment provider for de-energized multiple core power cable identification work.

How is this IP addressing a need/problem in the marketplace?
It increases the reliability of power cable identification when used together with clamping method.
