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.

Buyers choosing PD detectors often frame the decision as Chinese vs European brands. This guide reframes the comparison around what matters – application coverage, sensitivity, software, support, certification and total cost of ownership.
Chinese vs European Partial Discharge Detectors: What Buyers Should Actually Compare Read More »
Withstand voltage tests prove insulation can survive a specified stress; PD testing reveals the defects working toward failure. This article explains the difference, why both matter, and how they fit commissioning and maintenance.
Utilities across Latin America face ageing fleets, renewable integration and constrained budgets. Live-line inspection instruments – PD detection, thermal imaging and cable testing – support reliability programmes without large capital outages.
Railway traction substations convert grid power for trains and must operate with extreme reliability. PD testing – TEV, ultrasonic, HFCT and UHF – fits the non-stop operating regime of metro, commuter and heavy rail networks.
EV charging networks depend on feeders, switchgear, transformers and connections that must stay reliable under sustained load. This guide covers live-line inspection of the electrical infrastructure behind EV charging hubs.
