Online PD Monitoring vs Periodic Testing: A Cost-Benefit Case for Middle East Utilities Every Gulf utility eventually asks the same question: should we invest in permanent online partial discharge monitoring, or keep relying on periodic testing? Both have a place — but the economics shift strongly toward online monitoring on critical assets. This article lays […]

Desert Dust and Insulation Health: PD Detection for Gulf Utilities Desert conditions are hard on electrical insulation in ways that differ from every other climate. Between sandstorms, temperature extremes and low rainfall, Gulf utilities face a distinctive insulation failure pattern — and partial discharge detection is the tool that reveals it before failure. Understanding how

Substation Commissioning and PD Testing in Saudi Arabia and the UAE When a new substation is commissioned in Saudi Arabia or the UAE, the acceptance process is rigorous — and increasingly, partial discharge testing during commissioning is a mandatory step rather than an optional extra. Commissioning PD testing catches defects made during installation before they

Why UHF Partial Discharge Monitoring Demand Is High in the GCC Ask any transmission asset manager in the Gulf about their reliability priorities, and GIS condition monitoring will be near the top. The GCC operates one of the world’s highest concentrations of GIS-based substations under the most demanding climate on the network map, and UHF

SF6 Gas Monitoring for GCC Substations: Density, Decomposition and Safety Sulfur hexafluoride (SF6) is the insulating medium at the heart of GIS and HV breakers across the GCC. But SF6 is both expensive and a potent greenhouse gas — and its decomposition products are toxic. That is why SF6 gas monitoring has become a compliance

GIS Partial Discharge Online Monitoring in the Middle East: UHF Systems Explained Across Saudi Arabia, the UAE, Qatar, Kuwait, Oman and Bahrain, gas-insulated switchgear (GIS) carries a large share of transmission duty — and utilities in the region are investing in GIS partial discharge online monitoring faster than almost anywhere else. The reason is straightforward:

How to Choose a Partial Discharge Sensor for Substations in Vietnam and Thailand Vietnam and Thailand are expanding and upgrading their transmission and distribution networks at scale, and with that expansion comes a decision many engineers face for the first time: which partial discharge sensor should we standardize on? The right choice depends on your

Renewables Grid Integration and PD Risk in ASEAN Southeast Asia is adding solar and wind capacity at record pace — from utility-scale solar in Thailand and Vietnam to distributed rooftop PV across Malaysia, Indonesia and the Philippines. Every new connection changes the stress profile of existing switchgear and cables, and with it the partial discharge

Cable Partial Discharge Testing in High-Humidity Environments In tropical and coastal regions of Southeast Asia, cable circuits fail more often than any other network component — and the cause is frequently partial discharge inside joints and terminations. Cable partial discharge testing in high-humidity environments requires the right method, the right sensors and disciplined trending, because

GIS Partial Discharge Detection for Southeast Asian Utilities Gas-insulated switchgear (GIS) is the technology of choice for high-density substations across Southeast Asia — from Singapore’s urban grid to new transmission projects in Vietnam and the Philippines. The same sealed design that makes GIS compact also makes internal faults invisible: once a defect discharges inside an
