Onsite On and Offline Measurements

Power Diagnostix engineers are available on on short notice for various kinds of dielectric measurements such as partial discharge, loss factor, or others. Such on-sitemeasurements cover on-line and off-line diagnostics on rotating machines including large motors, partial discharge mapping on cable systems, survey-type measurements on gas-insulated substation equipment, and partial discharge acceptance testing and PD location on large transmission-class power transformers. All required instruments are provided, of course. VLF sources and high voltage sources can be provided as well.

Installation and Commissioning

The installation of partial discharge couplers, sensors, and instruments requires special technical skills and practical experiences in this field. Our service engineers and trained technicians are capable to take care of such jobs themselves or by supervising local staff. We do offer installation and commissioning service worldwide and in close cooperation with our contractor. Installation tools, safety equipment, and instruments for the first base line measurements are provided and a commissioning report is finalizing such service tasks. Please contact us directly in case of any special demand.

Consulting Activities

Power Diagnostix assists to analyze encountered defects, failure mechanism, and helps to improve the design of insulation systems. Further, support is provided to implement monitoring systems and to integrate embedded partial discharge sensors into GIS, cable accessories, and transformers for instance. Additionally, Power Diagnostix offers interpretation service for partial discharge pattern acquired by local testing groups. Instruments equipped with modem or VPN connection allow also having Power Diagnostix dialing in for performing remote measurements and diagnosis.
