Megger, a manufacturer and supplier of test and measurement equipment used within the electric power, building wiring, and telecommunication industries, has enhanced its KC series of test leads used with wind turbines. The new leads can be used either in a manufacturing plant or in the field for maintenance.
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.
Developed in conjunction with a wind turbine manufacturer, the KC-C test leads provide a solution for supplying leads that are long enough for testing the continuity of lightning protection conductors in turbines. They eliminate the time-consuming, inconvenient and unreliable process of engineers and technicians having to fabricate their own test leads.
Available in two lengths including 328 feet and 164 feet, 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. They are rated to 10 A. Each lead set includes two test leads fitted with a duplex handspike for probing the lightning receptors on the tips of the turbine blades.
The leads are also fitted with a Kelvin clip that is designed to offer ease of use, while providing consistent 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; as well as a cable guide on the cable reel to assist with orderly rewinding. These lightweight lead sets, weighing approximately 17 pounds, 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 20 pounds.
