Why Choose Our Electrical Testing

Key benefits that set us apart

Safety Assurance

Identify potential electrical hazards before they cause accidents or equipment damage

Reliability Optimization

Ensure protection systems operate correctly to prevent catastrophic failures

Regulatory Compliance

Meet NEPRA, IEC, IEEE, and NETA requirements for electrical system commissioning

Downtime Prevention

Predictive testing identifies degradation before unplanned outages occur

Our Process

How we deliver Electrical Testing

1

Test Planning

Review single-line diagrams, protection schemes, and develop comprehensive test procedures per NETA.

2

Safety Preparation

Coordinate outages, implement LOTO procedures, and establish safe work boundaries with PTW.

3

Equipment Testing

Perform electrical tests per IEC/IEEE standards using calibrated Megger and Omicron test equipment.

4

Protection Testing

Inject test currents/voltages to verify relay settings, coordination, and trip timing.

5

Results Analysis

Compare results against acceptance criteria, identify deviations, recommend corrections.

6

Report & Certification

Issue comprehensive test reports with recommendations and compliance statements.
