Kelvin lug 5K

for winding pins and bolted bars

The Kelvin lug is a robust two-pole measuring contact connecting to connection and winding pins, in particular in the case of transformers, and bolted connections and busbars in power engineering applications. It is designed for practical use under rough conditions. With 2 Kelvin lugs a 4-pole connection can be realised, so that the electric resistance of the test object can be measured with a suitable measuring instrument independent of the supply line resistances.

Of course, the Kelvin lug is not only suitable for resistance measurements, it can used for any low – resistance connection. However, its main field of application is the measurement of winding resistances, transforming ratios and phase angles of larger transformers in connection with our MRC7100 / PAW7100 transformer measurement system. For the complete connection of a transformer to the PAW7100 phase selection device, six to eight Kelvin lugs are required (depending on N conductor). The Kelvin lug 5K is available in different designs, which mainly differ with respect to the size, length and type of the cable connected and the corresponding plug.
