\”BAUR combines Kabelpruf – and diagnostic functions in mobile device presents new development on the ‘cable Conference 2009’ Sulz the BAUR testing, November 30, 2009 – and Messtechnik GmbH (Sulz/Austria) has her portable cable Tester frida\” expanded to a diagnostic function. With identical compact dimensions the new device frida TD in addition to the examination allows now includes determining the ageing State of medium voltage cables up to 20 kV and destructive. Basis for this diagnosis is the tangent-Delta method (tan?), also known as dissipation factor measurement. This determines the ratio of real power and capacitive reactive power. Measurements over several voltage levels allow reliable statements about the ageing condition of polyethylene insulation (PE, XLPE) and provide the basis for a condition-based maintenance. Checking the loss factor measurement with low-frequency voltage runs (VLF Checker). The truesinus generator ensures a perfect sine wave with 0.1 Hz – requirement for small deviations, as well as the maintainability and comparability of measurement results. Simplified cable diagnosis is through the intuitive user interface as well as the PC software developed by BAUR.
Interpret the readings and a trend analysis of repeated measurements fall so easily. Thus, the new version of the device is the ideal companion for network maintenance and service provider. Frida TD is available early summer 2010 on the occasion of the 16th Congress network technology cable Conference 2009 \”(30 November and 1 December at the Messe Erfurt) BAUR is unveiling its new development the broad audience. Long version: Water trees in time recognize some plastic-insulated cables (PE, XLPE) at their borders fall despite their robustness: Aging and damaged insulation materials lead to outages, this turn to unplanned and costly maintenance. Often water trees are fundamental.\” Spread out like small trees to imperfections in the insulation. A certain size they are to electrical trees\”, the desired effect of insulating structures, where local discharges take place then is no longer given.
