Electrical Testing of Primary Equipment — Ensuring Reliability and Operational Safety

In industrial and power generation/distribution environments, primary equipment forms the backbone of the power infrastructure. This includes components such as power transformers, high-voltage switches, current and potential transformers, disconnect switches, and surge arresters, among others,whose integrity and optimal performance are essential to the continuity and safety of the service.

Our Electrical Testing Service for Primary Equipment is designed to validate the performance, reliability, and compliance of this equipment under real-world operating conditions. Through precise measurements, standardized methods, and specialized technicians, we identify potential faults, performance degradation, and out-of-specification conditions before they become issues that affect operations.

Testing portfolio

Power Transformers

- Tangent Delta Test (Power Factor).
- Dielectric spectroscopy test (DFR).
- Frequency response test (SFRA).
To ensure the efficient and safe operation of power transformers.

High- and Medium-Voltage Switches.

We test the timing, opening/closing, contact resistance, and safe operation of switches throughout the distribution and transmission network.

Instrument Transformers: CTs and PTs

We verify the accuracy and response of current transformers (CTs) and voltage transformers (VTs) to ensure reliable measurement and protection.

Switchgear - Air and GS

We perform comprehensive testing on medium-voltage equipment, both open-air and GIS systems, to ensure proper insulation and reliable operation. 

Disconnect Switches and Blades

We inspect the condition and operation of disconnect switches and blades to ensure safe and trouble-free operation.

Testing of grounding systems

We evaluate the ability of surge arresters to reduce overvoltages and protect equipment against transient spikes.

Power quality

We test reclosers to ensure their performance and stability under actual load conditions.

Thermography

We test the internal resistance of batteries and conduct discharge tests on battery banks.
