Contact resistance measurements on circuit breakers

CPC 100

Universal primary injection test set for substation assets

"Extraordinary support starts with the very first contact. We always communicate from technician to technician, worldwide and around the clock."

The electrical power supply must be working reliably 24/7. We support you with free, professional technical support. Close to 40 support engineers and more than 100 training courses worldwide underline this fact. With service centers on all continents and a worldwide network of sales partners we are always close to you.

“The CPC 100 is a powerful solution for contact resistance tests and general system diagnosis on high-voltage circuit breakers during routine and commissioning testing.”

Benefits of this solution

Multi-functional test system

With CPC 100, you can perform the most common electrical tests on power and instrument transformers, rotating machines, grounding systems, power lines and cables.

Contact resistance measurements

The CPC 100 can measure contact resistance by injecting a current of up to 400 A DC into the contacts and measuring the voltage drop (using the 4-wire method).

Power/dissipation factor measurements

As well as the contact resistance measurements, you can also use the CPC 100, combined with the CP TD1 accessory, for dissipation/power factor measurements on circuit breakers.
