Increasing Confidence in Medium Voltage Cable Diagnostics

Cable diagnostics based on VLF TanDelta and VLF Partial Discharge measurement is most beneficial, when clear application procedures for new installations, for maintenance test after repair and for regular inspection are defined and evaluated in network tailored evaluation logics using clear action plans. The remaining lifetime estimation is the latest software invention and allows investment planning for asset managers. Huge saving potentials are realistic when the underground medium voltage cables can be operated to the optimum lifetime, while the reliability of the network is increased at the same time.
