Lightning protection measurement of wind turbines
Megger’s KC-C test leads are lightweight, making them safe for use at extreme heights, and are designed to work with Megger’s DLRO2 low resistance hand-held ohmmeter long test lead mode to measure the resistance of the lightning protection circuit of wind turbines. These new leads can be used either in a manufacturing plant or in the field for maintenance. The KC-C test leads provide a complete and convenient solution for supplying reliable leads that are long enough for testing the continuity of lightning protection conductors in turbines. They offer accurate results and eliminate the time-consuming, inconvenient, and unreliable process of engineers and technicians having to fabricate their own test leads. Available in two lengths, 328ft and 164ft, each testing lead comes standard on a heavy-duty cable reel that is fitted with a friction brake to avoid tangles while reeling out the cable, and are rated to 10A. Each lead set includes two test leads fitted with a duplex handspike for probing the lightning receptors on the tips of the turbine blades. They are also fitted with a robust Kelvin clip that is designed to offer ease of use, while providing consistent and reliable connections that are needed to ensure accurate and repeatable results. The KC-C test leads also feature hook terminations marked with C or P to ensure the right connections are made, and a cable guide on the cable reel to assist with orderly rewinding. These lightweight lead sets, weighing approximately 17lbs, use a duplex connect test lead system that allows probes or clips to be changed quickly and easily on-site. When combined with the DLRO2, they have a combined weight of less than 20lbs.
