Abstract
Successful delivery of electrical power depends upon the reliability of system such as protection of electrical equipment, delivery media and condition of environment. Unlike overhead transmission lines, an underground cable is not exposed to the variable weather condition, so the reliability of electrical power delivery is more in comparison with overhead lines. An experimental set-up has been developed to conduct switching transient of power cable with induction motor acting as a load, and the current and voltage data are saved in a digital storage oscilloscope during the transient operation and analysed properly. Switching operation mainly creates surges and moves through the cable circuit. R, L and C parameters of the cable have been calculated using traditional method of determination. The aim of this paper is mainly to energise a low-voltage distribution cable and to study the behaviour of switching transient. In addition to switching transient, different types of fault such as line to ground fault and double line to ground fault have been created in an unloaded cable. A MATLAB/Simulink platform has been used to study the cable parameters and its characteristics.
