TV30 DAC Test & Diagnosis System

The TV30 is a DAC (Damped AC Voltage) test set with a peak voltage of 30 kV. The test set can be used for quality control on newly installed, repaired or service-aged MV cable systems with reliable results and an appropriate assessment of the condition of the cable insulation as well as of the accessories. This is the key to successful operation of the distribution and transmission networks.

DAC voltage test and diagnostic measurements (PD and TD) 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.

Features

Time-saver at your service for cable diagnostics：Connect — Automatic — Inspect

The on field test is very simple, after the connection between TV30 and cable is completed, the operating software will guide you through the entire process.

Connect: After the necessary inspections and pre-tests are completed, only need few connections about DAC test.

Automatic: Second step is just follow the steps of operating software, only need to input some necessary parameters of tested cable, others system will complete it automatically.

Calibration

Automatic test

Inspect: The test and diagnosis will performed, live PD mapping will automatic displayed on the screen.You only need to check the results and choose whether to output a test report.
