How We Work

Your Field Test Team

We do

Testing, commissioning, maintenance, repair and troubleshooting of electrical apparatus.

We work with

Utilities, EPCs, engineering firms, OEMs and industrial owners.

About

Owner-Operated, with OEM Field Experience

Reactive Power Services is led by a certified engineering technologist with about 18 years in high voltage testing and commissioning, including field service roles with major transformer manufacturers.

The name comes from the machines we spend our days with. Transformers, reactors and capacitor banks are reactive power equipment, and they are the core of what we test and maintain.

You deal directly with the technologist doing the work, from mobilization through to the final report. We come prepared with the equipment to complete any task.
