Precision Testing. Proven Performance.
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.
We test and commission transformers, switchgear, AIS/GIS substations, CT/VTs, cables, motors and batteries, using advanced diagnostic
equipment including Megger analyzers. Our recent work ranges from HVDC and GIS substations to 1 GW-scale solar and BESS projects, delivered for utilities and global EPC contractors.
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 Testing
Our transformer testing covers electrical, magnetic, insulation and oil-condition checks. Asset owners get a clear picture of the transformer’s health before
energization and throughout its service life.
- Transformer Turns Ratio (TTR)
- Winding Resistance
- Excitation Current
- Magnetizing Current
- Magnetic Balance
- Tan Delta Test
- Calibration for OTI and WTI
- Load tap-changer continuity, timing and dynamic resistance
- Leakage reactance & short-circuit impedance
- Sweep Frequency Response Analysis (SFRA)
- Insulation Diagnostic Analyzer (IDAX)
- Oil Purification
- Oil Analysis, including DGA and Furan
Switchgear, AIS / GIS & Protection Testing
We test and commission medium-voltage switchgear, circuit breakers, instrument transformers and protection systems for utility substations, solar plants and industrial facilities. Our SF6 gas handling, partial discharge (PD) monitoring and thermal imaging capabilities find insulation and contact defects early, before they turn into failures.

Cable Diagnostics & Fault Location
We test new and in-service power cables to confirm their insulation is sound before energization and to pinpoint faults quickly when they occur. Recent cable
work includes MIDOR project commissioning and cables testing, MV cable testing across the 1.1 GW Obelisk PV area, and testing of 250 cable drums on the HSR project.
