Study of the Heat Equation and the Effect of Temperature Inside an Electric Cable Consisting of Aluminum and Copper Metals

Abstract

In this paper, we study the mathematical physics model; partial discharge (PD) mapping and power cable fault location are approaches based on the principle of time domain reflection (TDR) measurement, influenced by the power cable's height Frequency wave propagation properties. Furthermore, power cables. They're increasingly being used to transmit electrical energy and communication signals simultaneously. Smart grids are an example of such technology. Power cables are exposed to a variety of temperatures when in use. Changes in the load current flowing through the cable cause differences. As a result, it is essential to Recognize how temperature affects the high-frequency characteristics of power wires. Temperature changes advance Errors in TDR measurements, according to simulations, and result in numerical solutions undertaken in this study. It's also shown that when the cable's temperature rises from25°C to 60°C, the attenuation increases by 1° and the propagation velocity rises by 1°.a 4-percentage-point average The phase constant, on the other hand, drops by order of magnitude on average. The findings imply that temperature effects must be considered while making decisions. Communication channels in power cables are designed.
