“…This reduces the life of the insulation of supply cables and reduce the reliability of the entire system. [1] The nature and magnitude of operating voltages in the VFD depends on the length of the supply cable [2], the method of modulation voltage [3], the stator winding structure, composition and parameters of elements in the VFD. With that said insulated power cables for variable frequency drive to withstand higher operating load for the entire lifetime.…”

Abstract. This article describes an approach for evaluating experimental cable insulation resistance electro-thermal aging, typical for the drive frequency being adjusted. It estimates the average time until the insulation breakdown when exposed to a sample of high electrical loads. The possibility for an adequate choice of insulating materials, which are used in the insulation of VFD cable and shown ways to improve testing methods.
