DAC M60
A class of compact, lightweight and versatile DAC MV cable test systems with withstand voltage test, PD analysis and PD localization
The “Damped Alternating Current” (DAC) test systems M30, M40 and M60 form an exceptionally compact, lightweight and versatile class of systems for testing and diagnosing Medium-voltage transmission cables. They are programmable and have automatic withstand voltage testing, partial discharge (PD) measurement and analysis as well as PD localization. The controls, measurement and presentation of results is user-friendly, with a common software platform for the entire range of our products.
A DAC cable test does not just provide a rudimentary “good/bad” statement, it is an advanced analysis and diagnostic concept. It enables the condition of the cable insulation to be assessed of newly installed, repaired or in-service cable systems and thus supports the asset management process of the cable operator.
