HV Diagnostix provides testing services to customers when they do not have the equipment or the expertise to do so themselves. We use this experience to support the application of our products and to demonstrate the benefits of insulation diagnostics to our customers.

We have three categories of service we offer:

On site testing

We can come to your site and perform testing of your assets. Generally either to demonstrate the benefits of diagnostics or to assist with problems that you are having.

Diagnostic Consulting

Let us assist you in diagnosing the condition of your HV insulation by providing an independent assessment of the diagnostic measurements you have.

General Training
