Electrical Testing & Commissioning Services in Pakistan.
TransfoLine delivers end-to-end electrical testing and commissioning solutions for industrial plants, power generation units, grid substations, and commercial facilities. We execute rigorous diagnostics using calibrated instruments from Megger, OMICRON, FLIR, and Fluke to ensure peak efficiency, compliance, and operational safety before and after energization.
What is electrical testing and commissioning?
Electrical testing and commissioning is the systematic engineering process of verifying, inspecting, and testing every component of an electrical installation—including transformers, switchgears, protection relays, cables, and grounding networks—to ensure full compliance with international standards (IEC 60076, IEEE, NETA) and safe energization without downtime.

Frequently Asked Questions.
Key questions answered by our testing and commissioning engineers.
GENERAL What is electrical testing and commissioning?
It is the formal technical verification of electrical systems to ensure that all equipment operates safely, meets manufacturer specifications, and complies with IEC/IEEE standards before and during service.
EQUIPMENT What instruments does TransfoLine use?
We utilize calibrated precision instruments from Megger (insulation & relay test sets), OMICRON (secondary injection), FLIR (thermal imaging), and Fluke (power quality analyzers and multi-meters).
LOCATION Do you provide testing across all Pakistani cities?
Yes. We mobilize testing teams across Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, and Gilgit-Baltistan with complete mobile testing units.
REPORTING How soon do we get the test certificate and report?
Preliminary on-site findings are provided immediately upon test completion. Full signed and stamped engineering reports with graphical data and recommendations are delivered within 24 to 48 hours.
