Poor termination and jointing work causes most premature cable failures. This guide covers quality control for cable terminations – workmanship, testing, documentation – and why acceptance testing catches defects early.
Detecting PD is the first step; locating it is what makes the finding actionable. This guide covers localisation techniques across GIS, transformers, cables and switchgear – time-of-arrival, acoustic, HFCT and OWTS methods.
Shunt capacitor banks support voltage and power factor across the grid. This guide covers monitoring of capacitor bank voltage, current and health – what to measure, what the readings mean and how monitoring protects the bank.
Overhead distribution lines are the widest exposed asset in any grid. This guide covers PD detection on insulators and line equipment – ceramic insulator sensors, ultrasonic inspection and the practical limits of line monitoring.
Frequently asked questions about partial discharge detectors – what they measure, which technique to choose, live testing safety, online vs handheld, OEM supply and costs – answered in plain language for buyers.

Artificial intelligence is entering partial discharge analysis – pattern recognition, noise rejection and trend prediction. This article separates what the technology genuinely changes from what remains engineering judgement.
Calibration keeps PD measurements comparable over time – the foundation of trend-based maintenance. This article explains calibration principles, practical schedules and what to require from your instrument supplier.
Instruments alone do not make a PD programme – trained engineers do. This guide explains what effective PD testing training covers, how to build in-house capability, and what to demand from an instrument supplier’s training support.
