PD Measurement Without Service Interruption

Effective condition assessment thanks to modern PD measurement technology

The evaluated measurement data provide valuable insights for an efficient and sustainable maintenance strategy.

Partial discharge measurement (PD measurement) is a central method for assessing the condition of electrical systems. Partial discharges are among the most important parameters monitored during the manufacture, installation, and operation of equipment. To date, however, PD measurement has rarely been used during ongoing operation – primarily due to the technical limitations of conventional systems. Many available solutions were complex, expensive, difficult to scale, and did not record all relevant system parameters.

Our solution: PRY-CAM

With PRY-CAM, we rely on an innovative technology that enables PD measurements wirelessly, safely, and without shutting down the system.
The system consists of a broadband antenna sensor and a high-speed acquisition unit – entirely without a conductive connection to the test object. This allows us to perform precise online PD measurements and reliable fault diagnoses while the system remains in operation.

We support you in:

• increasing supply security,
• extending the service life of your equipment,
• reducing maintenance costs, and
• identifying risks at an early stage.
