Testing & Consulting

In addition to individual products and system solutions, Von Roll Dolph’s® also offers consulting and testing services. From tests on individual products or objects to the recommendation and qualification of complete insulation systems in the sectors of low and high voltage, electronic and electrical applications across all industries. We are globally represented on all continents with our laboratories and test facilities.

In addition to consulting and auditing services, we also offer corresponding annual training courses in a wide variety of areas. These are offered as open events, as well as for closed groups.

Safely operating electric motors and generators depends on one key element: reliable insulation. This is especially true when the systems are powered by high voltage. For over 100 years, the Von Roll Institute has specialized in testing insulation systems for high-voltage rotating machines. The institute is certified to ISO 9001 and ISO 14001.

We test every component of your insulation system – individually and in combination – according to your specific requirements. With our support, you increase the reliability and life span of your machines, carry out qualification programs in accordance with international standards and avoid production downtime. These benefits really pay off.

All tests are also carried out in our laboratories in the USA for low-voltage rotating systems and can include UL certification if required.

Our Von Roll Institute operates as a separate unit and can be accessed at the following link.

As the condition of the resin has a significant influence on the quality of the impregnation and thus the insulation, it is important to ensure that the resin is in good condition. For this purpose, we offer our customers who use our resins the service of tank inspection. After an appropriate advisory discussion, customers can send us samples of the resin at agreed intervals, which we analyses and provide our customers with a technical report about the resin condition.

If you are not yet part of our program, you can contact us at any time via the contact form or reach out your local sales representative.
