Electrical Testing of Power Cables — Reliability and Safety in Power Transmission

Power cables are critical components in any electrical system. Their function is to transmit power from substations, generators, or main switchboards to loads or distribution centers. When a cable fails, the consequences can include service interruptions, equipment damage, safety hazards, and high operating costs.

Our Electrical Testing service is designed to assess the integrity, performance, and safety of cables, identifying hidden faults, installation defects, and insulation degradation before they cause major problems.

Power Cable Testing

VLF Testing. IEEE 400.2 Standard

We conduct Very Low Frequency (VLF) tests to assess the condition of power cables.

Delta Tangent Tests

It measures the dielectric loss of the cable insulation to identify degradation, moisture, or premature aging of the insulating material.

Partial Discharge (PD) Testing

It enables the detection of internal defects in the insulation of medium- and high-voltage cables before they develop into critical faults.

Reflectometry

Detects and locates discontinuities, faults, and damage in cables using reflective signals for accurate fault diagnosis in power lines.
