Our high voltage (HV) laboratory can test and evaluate materials and the study of different HV phenomena. We can help provide the necessary information on the condition of assets as well as undertake product testing prior to market introductions. We provide quality voltage testing services supported by a world-class high voltage test facility to provide trusted support to aid our customers in making the right product investment choices.
We offer an independent, third-party service from knowledgeable technical staff with experience in advanced testing and diagnostics that provide clients with the assurance they are receiving accurate, reliable test results to facilitate informed decision-making.
For over 30 years, our capabilities in high voltage apparatus and insulation systems have successfully supported many of the largest power systems in the world. Our facilities and services have been used extensively in both electrical industry transmission and distribution research programs and by manufacturers for product development and testing standards. We welcome customer involvement to support robust testing and evaluations and work together to develop enhanced high voltages products.
Services include comprehensive indoor, outdoor, mobile, and specialized environmental testing technology supported by evaluation expertise.

Environmental Testing Chamber
Our unique environmental testing chamber can simulate fog, freezing rain and icing conditions continuously, while monitoring the performance of insulation for test voltages of up to 350 kV. Our facility accommodates contamination testing of external insulation under standard and non-standard conditions.
By simulating a wide range of possible environments we are able to subject components to accelerated conditions that provide accurate assessment and evaluation of component qualification.
These tests are of particular interest to utilities interested in the performance characteristics of various insulators. The test results can be used to determine the best insulator for a specific utility application in their unique region. Icing tests on outdoor grounding and disconnect switches can be done to evaluate mechanical performance in harsh conditions.
Tracking Wheel Test Facility
Our tracking wheel test facility enables the tracking and erosion tests on polymeric insulators that are required by various national and international standards. This facility can also be used for accelerated aging tests on insulation materials.
