The new KC series of test leads, available from Megger , were developed in conjunction with leading manufacturers of wind turbines, and provide a complete and convenient solution to the problem of finding reliable test leads that are long enough to be used for testing the continuity of lightning protection conductors in wind turbine blades.
Believed to be the first commercially available products of their type that have been specifically designed for wind turbine applications, Megger’s new test leads eliminate the need for engineers and technicians involved in wind turbine testing to fabricate their own test leads – a time consuming and inconvenient process – or to resort to makeshift arrangements that may deliver uncertain results.
KC-series wind turbine test leads are available 100 m, 50 m and 30 m versions, and are equally suitable for use on site or in the manufacturing plant. For convenience and ease of handling, these test leads are supplied as standard on a heavy-duty cable reel that is fitted with a friction brake to avoid tangles when paying out the cable.
The test leads are terminated with large robust Kelvin clips that have been specially designed to offer ease of use while providing the consistently reliable connections needed to ensure accurate and repeatable test results. Included with each lead set is a 5 m cable fitted with a duplex handspike for probing the lightning receptors on the tips of the turbine blades.
KC-series test leads are ideally suited for use with Megger DLRO10HD low-resistance digital ohmmeters, which combine robust construction with a high test current capability. They also have an IP65 protection rating with the lid closed, and an IP54 rating when the lid is open and tests are being performed, which means that they can be safely used outdoors even when it is raining.
While these features make DLRO10HD ohmmeters an excellent choice for wind turbine applications, KC-series test leads can also be used successfully with most modern types of low-resistance ohmmeter.
