Guides

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.

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.

Battery energy storage systems connect to the grid through switchgear, transformers and MV cables that must meet the same reliability standard as any substation. This guide covers live-line inspection of BESS electrical infrastructure.

Indonesia’s grid expansion, industrial parks and new generation connections create steady demand for inspection services. Live-line PD testing, thermal imaging and cable testing support utilities and contractors across Java and beyond.

Malaysia is building data centres and grid capacity at scale. This guide covers live-line inspection of switchgear, transformers and cables for utilities, data centre owners and contractors across Peninsular Malaysia and Sarawak.

Insulation resistance (IR) testing and partial discharge (PD) testing measure different properties of the same insulation. This article explains what each detects, why a good IR reading does not rule out PD, and how to combine them in maintenance practice.

Thailand’s power sector is investing in grid expansion, renewable integration and ageing asset management. Live-line inspection instruments – PD detection, thermal imaging and SF6 leak checking – support utilities and contractors across Thai substations.
