Guides

A predictive maintenance programme moves electrical asset care from calendar-based schedules to condition-based decisions. This guide covers instrument selection, baseline establishment, patrol scheduling, alarm rules and programme governance.

Commissioning a new or refurbished substation bay is the best time to establish equipment baselines. This checklist covers the live-line detection tests – PD, thermal, SF6 and cable – that should be part of every commissioning programme.

Partial discharge testing is the standard online method for assessing stator winding insulation in generators and large motors. This article explains coupling capacitor, HFCT and bar-to-bar measurement approaches, and how to interpret stator PD trends.

Cable fault location and partial discharge testing are both essential cable maintenance tools – but they answer different questions at different stages. This article explains when to use TDR-based fault locating, when to use PD testing, and how they fit a cable maintenance programme.

Southeast Asia’s solar fleet is expanding rapidly across Vietnam, Thailand, the Philippines and Indonesia. Inspection instruments – thermal imaging, PD detection and cable testing – keep plant electrical equipment reliable in tropical conditions.

The Philippines is expanding and modernising its grid to support demand growth, renewable integration and island interconnections. Live-line PD testing and inspection instruments help utilities and contractors manage older assets alongside new build.

For electrical testing distributors and agents, partial discharge detection instruments are a growing line with repeat demand. This guide explains the distributor model, what to evaluate in a manufacturer, and how partnerships with Chinese manufacturers like HUWOR work.

Data centre construction is surging across Southeast Asia, and the power equipment feeding the facilities must be proven and maintained to the highest reliability standard. This guide covers live-line testing of switchgear, transformers and UPS input systems for data centre electrical rooms.

SF6 remains the dominant GIS insulation medium, but environmental regulation is pushing the industry toward alternatives. GIS owners should strengthen SF6 management now – leak detection, emissions accounting and monitoring – while tracking the transition.

Dissolved gas analysis (DGA) and partial discharge (PD) testing are the two main diagnostic windows into transformer insulation. This article explains what each detects, their blind spots, and how combining them strengthens transformer asset management.
