Damped AC (DAC) Cable Testing System 60kV

After-laying testing and diagnosis of newly installed, repaired or service-aged HV cable systems with reliable results and an appropriate assessment of the condition of the cable insulation as well as of the accessories is the key to successful operation of the distribution and transmission networks.

Cable diagnosis by partial discharges and dissipation factor (tan δ):

DAC voltage test and diagnostic measurements (PD and tan δ) provide for reliable detection of poor installation, failures due to inappropriate laying, failures in accessories or deterioration in cable insulation due to aging. It allows much more than a simple “go or no-go” decision. DAC testing is an advanced maintenance tool which supports asset management and grid operation as well.

The PD Measurement gives users the certainty to see nearly all PD inceptions during test voltage application. As a result, it allows to turn-off the test if PD appears and to avoid a breakdown during the test if not appropriate (cable under specific surveillance will be exchanged or repaired soon). Additionally, localization and identification of PD patterns (e.g. joints) is possible. All PD measurements are according to IEC standard(s) and have been proven by experience over the last 14 years.

The Dissipation Factor (tan δ) estimation is based on the determination of the damping factor of the DAC voltage itself. This measurement gives a reliable indication of the integral deterioration of the cable insulation. Especially service aged oil-impregnated transmission power cables aged for more than 40 years can be differentiated into groups of highly and acceptably aged ones. In case of investments for exchange programs this method supports the decision which cable has to be exchanged first on the best available bases.
