Electrical Testing Services

Our knowledgeable staff and the equipment to troubleshoot and test complete electrical systems as well as:

Dielectric Fluid Analysis Oil Lab Services

We have a complete in-house laboratory dedicated to the analysis of dielectric fluids, our clients can plan preventative maintenance on their equipment prior to a catastrophic failure. This can be done through regular trending data analysis. Dielectric liquids are used as electrical insulators in high voltage applications, e.g. transformers, capacitors, high voltage cables, and switchgear (namely high voltage switchgear). Its function is to provide electrical insulation, suppress corona and arcing, and to serve as a coolant.

Electrical Protective Equipment Testing

We have a complete in-house laboratory dedicated to testing of electrical protective equipment & goods. We offer full service testing and re-certification of rubber gloves, sleeves, blankets, line hoses, and hoods. Our facility is equipped with state-of-the-art equipment for the complete testing of these products, including washing, visual inspecting and electrical testing. All rubber protective equipment tested by the Electric Technologies Lab undergoes this rigorous sequence to ensure that your employees are always using safe equipment.

Insulating Fluid Sampling Oil Sampling Services

Our field technicians are trained to safely and properly collect an oil sample to ensure that it’s integrity has not been compromised.

Infrared Survey Services

Let our Level I and Level II Thermographers perform infrared surveys of your electrical equipment.

Installation & Retrofit

We can retro-fit high voltage equipment in existing applications, as well as the installation of new equipment, plus Re-gasketing of Oil-Filed Equipment.

Mobile Vacuum Oil Processing

Using degasification, dehydration, filtration, and purification techniques, the ETI Mobile Vacuum Oil Processing Unit can extend the life of the insulating fluid in high voltage equipment.
