Safely operating electric motors and generators depends on one small detail: reliable insulation.

More than the sum of its parts

Test the components of your high-voltage insulation

Safely operating electric motors and generators depends on one small detail: 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, and is certified to ISO 9001 and ISO 14001.

Qualification programs in accordance with international standards

We test every component of your insulation system for you – individually and in combination – according to your specific requirements. With our support, you increase the reliability and lifespan of your machines, carry out qualification programs in accordance with international standards and avoid production downtime. This really pays 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.
