Delta Testing Services

How We Do More In More Places

Most electrical testing companies will test the specified equipment, then simply generate a report and leave the customer with the problem. Delta Testing crews don’t leave until the job is done and you are operational. We run the required testing and perform any needed services, maintenance, repairs or upgrades to get your equipment operating at the optimal level.

We run five crews with service trucks that are fully equipped to meet any electrical need, from micro-processor-based protective relaying and the associated schemes, to all manner of electrical apparatus testing, maintenance, service, repair, and replacement. Our primary work ranges from low-voltage systems to power plants as large as 1000MVA operating at 230kV connected to the bulk electrical system.
