Power Domain Technical Services LLC brings expert engineering to primary and secondary systems across 400kV, 220kV, 132kV, 66kV, 33kV & 11kV substations — where precision, safety, and reliability are paramount.
SCOPE OF VOLTAGE CLASSES
Primary systems (CT/VT/CB/DS, LCC/GIS interlock) and secondary systems (protection relays, SCS signaling) tested end-to-end according to IEC, IEEE, and UAE utility standards.

Transformer Commissioning
Outdoor Substation — UAE
From protection relay testing to transformer commissioning, we deliver precision engineering across all HV, MV, and LV electrical systems.
When precision matters, our team delivers with expertise, safety, and speed.
Our team comprises senior electrical engineers and certified technicians with deep hands-on experience across HV, MV, and LV systems in diverse industries.
We adhere to rigorous HSE protocols and quality assurance procedures on every project. Safety is never compromised, regardless of project size or deadline pressure.
We understand the cost of unplanned downtime. Our mobilization process ensures rapid deployment to site with minimal lead time, keeping your project on schedule.
We invest continuously in the latest calibrated test equipment — from microprocessor-based relay testers to precision power analyzers — ensuring accurate, reliable results.
All work is performed in accordance with IEC, IEEE, and client-specific standards. Our detailed test reports provide full traceability and documentation for regulatory compliance.
No two projects are identical. We collaborate closely with clients to understand their specific requirements and deliver tailored engineering solutions that fit their budget and timeline.
Our expertise spans a broad range of industries, delivering tailored electrical testing and commissioning solutions wherever precision matters.
