High-Voltage Electrical Insulation Systems Testing and Certification

High-voltage (HV) electrical insulation system testing  

We offer HV electrical insulation system evaluations that are specifically designed to address the performance of HV form-wound rotating machinery and HV power and distribution transformers. The tests are performed on actual form-wound coils or transformer coils to globally recognized Institute of Electrical and Electronics Engineers (IEEE) or International Electrotechnical Commission (IEC) standard test methods. Upon completion, a thermal class rating certification is issued.   

Testing HV electrical insulation systems to globally recognized standards  

Our high-voltage electrical insulation system services let specifiers and end users know that the insulation system has been tested and certified to meet the requirements of the globally accepted test methods. 

Why UL Solutions for HV electrical insulation systems testing and certification

We uniquely evaluate and certify insulation systems. In addition to assessing insulation materials as individual components, we also evaluate the applicable system as a whole. This allows us to determine if components interact in unsafe ways or react chemically at certain maximum temperatures, which may cause product failure or other hazards to occur.

Plus, we’re committed to being your single-source service provider, which is why we are constantly expanding our insulation systems portfolio to better serve component manufacturers and original equipment manufacturers (OEMs). Having access to our full-suite of services, along with our technical team, allows you to easily keep pace with the new technological developments in your respective industry. That’s how we help you achieve what’s possible.
