Effect of Combined Stresses on the Electrical Properties of Low Voltage Nuclear Power Plant Cables

Abstract

Energy is the heart of any industry since each industry uses energy. One of the most critical sources for energy generation is the nuclear power plants. The plants building needs a lot of investments and a pivotal role from the financial services sector in providing the necessary finance for the capital works. Control, instrumentation and low voltage power cables have a vital role in the operation, reliability and lifetime of these plants. The performance of these cables has an effect on the energy industry and the industries which use this kind of energy source. During operation, these cables are subjected to different stresses such as thermal, environmental, electrical and mechanical stresses so, condition monitoring of these cables is a must. This paper discusses a combined aging mechanisms effect on the electrical parameters of these cables. The assessment was done by monitoring the capacitance and the loss factor of the cables.
