Megger launches fully isolated DAC partial discharge test set

Megger has announced the launch of the MV DAC-30, a fully isolated DAC (Damped AC Voltage) partial discharge test set with a peak voltage of 30 kV.
  The MV DAC-30 by Megger can be used for quality control on newly installed cables as per IEEE 400.4 standard. The test set prevents unplanned outages, saving you time and money, and may also be used for condition monitoring on aged cable circuits.
The main use of the DAC test set is to identify, evaluate and locate partial discharge (PD) faults in the cable insulation and accessories of all types of medium voltage power cables. PD activity is an indication of incipient faults in the insulation and is therefore widely regarded as one of the best ‘early warning’ indicators of the deterioration of medium and high voltage insulation.Partial discharges are regarded as the main breakdown cause for MV and HV cables. Performing offline PD measurements on MV and HV cables using a DAC voltage helps support the asset management process so that reliable decisions can be made for maintenance or replacement activities.Since the DAC frequency of the test voltage is close to nominal AC service conditions, all measured PD activities can be effectively evaluated and are comparable with the power frequency. The PD inception voltage (PDIV) and PD extinction voltage (PDEV) can be easily determined due to the decaying amplitude of the test voltage.
According to Megger, the MV DAC-30 is the first unit worldwide where the power source and PD coupler are fully integrated into a single portable unit. Thanks to the test sets fully integrated systems, there are no parts under high-voltage potential, ensuring highest level of safety for operators and the environment. In addition, to simplify transportation, the unit consists of two modules weighing less than 35 kg each.
