Powering infrastructure that keeps business moving.
From Installation to Energization
We install and contract electrical infrastructure that keeps business and industry moving.
APT’s installation teams are backed by the company’s testing and commissioning expertise. Transformers, medium-voltage switchgear, cables and
earthing systems are installed by the same engineers who test them. Each system is checked with calibrated test equipment and handed over ready for energization.
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 Installation
- M.V Switchgear Installation
- Transformer Oil Filtration
- Oil Purification
- MV Cables Testing
- Cable Tracing
- Grounding Verification
- Earth Measurement
- Lightning Protection System (LPS) Testing
- PV Strings Testing
- Primary Equipment Testing
- Pre-commissioning up to Energization
Transformers & Substations
A transformer installation is only complete once the unit is proven healthy. APT installs transformers on site, then treats the insulating oil and runs a full set of diagnostic tests before the transformer is energized. The same tests become the baseline for its maintenance throughout its service life.
Installation & Oil Treatment
- Transformer Installation
- Transformer Oil Filtration
- Oil Purification
- Oil Analysis, including DGA and Furan
Tests Before Energization
- Transformer Turns Ratio (TTR)
- Winding Resistance
- Excitation & Magnetizing Current
- Magnetic Balance
- Leakage Reactance & Short-Circuit Impedance
- Tan Delta Test
- Sweep Frequency Response Analysis (SFRA)
- Insulation Diagnostic Analyzer (IDAX)
- Calibration for OTI and WTI
- Load Tap-Changer Continuity, Timing and Dynamic Resistance
M.V Switchgear Installation
APT installs medium-voltage switchgear and completes the checks needed before it goes into service, including breaker operation, protection and insulation.
Because our engineers handle installation, testing and commissioning, the switchgear passes to the next stage without a hand-off between contractors.
- M.V SWG Installation
- Circuit Breaker Analyzer
- Protection Relays Testing
- Primary Current Injection
- SF6 Gas Refill & Evacuation Unit
- SF6 Gas Analyzer
- Contact Resistance Testing
- Hipot Tester
- CT/VT Testing
- Surge Arrester Testing
- SF6 Leak Detection
- Earth Measurement Analysis
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.
