Electrical service on site: maintenance, testing and commissioning,
backed by over 35 years of experience. Trusted expertise. Proven
performance.
Maintenance Backed by Precision Diagnostics
Advanced Power Technology (APT) is an independent electrical engineering, testing, maintenance and commissioning specialist with extensive experience in
power systems, serving utilities, EPC contractors and industrial clients across large-scale energy and infrastructure projects.
Our maintenance teams use the same diagnostic tools we use for testing and commissioning, including Megger analyzers, partial discharge detectors, thermal imaging and oil analysis. This lets them find the cause of a fault, not just its symptoms. From transformers and switchgear to cables, motors
and batteries, we help asset owners fix faults quickly and catch developing problems before they turn into outages.
Based in Riyadh, APT is ready and mobilized to deliver its full range of electrical installation, testing, commissioning and maintenance services
across KSA, supporting utilities and transmission networks, EPC contractors, renewable energy developers, and industrial and oil & gas facilities.

Transformer Maintenance & Oil Filtration
The transformer is one of the most critical and costly assets in any substation. We maintain transformers on site, from cleaning and restoring components to filtering and purifying insulating oil. Every job is backed by diagnostic testing, so the transformer’s condition is checked before it returns to service.

M.V Switchgear Maintenance
Switchgear failures are often caused by worn contacts, loose connections, insulation breakdown or SF6 gas loss. Our engineers inspect, service and test
circuit breakers, panels and protection systems. Each fault is found and fixed, and the equipment is proven healthy before it goes back into service.

Condition Monitoring & Fault Diagnosis
We combine online monitoring with targeted diagnostic tests to locate faults and track equipment condition over time. Many of these measurements are taken while the equipment is running, so operations continue during the assessment.
