Underground cable power transmission and distribution system are susceptible to faults. Accurate fault location for transmission lines is of vital importance. A quick detection and analysis of faults is necessity of power retailers and distributors. This paper reviews various fault locating methods and highly computational methods proposed by research community that are currently in use. The pa...

Environment monitoring is important for the safety of underground coal mine production, and it is also an important application of Wireless Sensor Networks (WSNs). We put forward an integrated environment monitoring system for underground coal mine, which uses the existing Cable Monitoring System (CMS) as the main body and the WSN with multi-parameter monitoring as the supplementary technique. ...

Today, it is very challenging to manually find underground cable faults like wear and tear or rodents, because costs more takes time. Finding the fault sources also difficult entire line must be dug check for faults. Our suggested system utilises an Arduino- microcontroller help locate fault's exact location. The standard concept of Ohm's law applied in this system. location shorted determines ...

With the growing requirements imposed by regulatory authorities, grid operators and power utilities firms are confronted with challenging task of ensuring reliability, safety, resilience distribution networks amid aging asset infrastructure a lack resources. Over past 15 years, health index (HI)-based analysis has become an increasingly popular management tool for several utilities. This strong...

A cable loop source calibration system is developed for the Jiangmen Underground Neutrino Observatory, a 20 kton spherical liquid scintillator neutrino experiment. This capable of deploying radioactive sources into different positions detector in vertical plane with few-cm position accuracy. The design and performance prototype are reported this paper.

This paper introduces three different procedures for improvements in the accuracy at very low frequencies of time domain simulation models for overhead lines and underground cables. In the first two methods, a suitable modification is introduced to the functional form of the rational function approximated in the curve fitting procedure for the phasedomain model, such that the model is perfectly...
