Overhead Line Corrosion Detector - OHLCD
OHLCD is a non-destructive testing method for determining the condition of overhead power conductors.
The remotely controlled device is passed along the ACSR conductor and measures the integrity of the galvanizing layer on the steel core strands. Loss of galvanizing is a precursor to the onset of galvanic corrosion between the steel and aluminium cores of ACSR and provides an early warning of the potential need to replace the conductor.
OHLCD was developed by Cormon and the CEGB research organization and is widely used by transmission companies in the UK, France, Eire and Sweden. A live line working capability has been developed for areas where outages can be difficult to obtain.
