Continuous Partial Discharge Monitor (QPDM-C RAU)

0.00

By utilizing online PD sensors; HFCT and TEV. Remote acquisition units (RAU) monitor power cable conditions and transfer the acquired data to the PDM unit. The PDM can monitor multiple cables at the same time. The automatic interpretation and analysis by Expert Software allow the incipient faults to be avoided and the condition of long term health of insulation system to be simply and effectively monitored over the life of cable.

Features

  • Highly accurate periodic PD survey of HV/MV power cables eliminates risk of unplanned outages
  • Precise PD localization (within 0.2% to 1% of cable length) minimizes maintenance expenditure
  • Accurate categorization of different activities captured by system
  • Robust and rugged design to maximize portable operation life and support inspections / testing for extended period of time
  • Advanced denoising and filtering help to remove background noise efficiently
  • Online and non-intrusive PD measurement

Options

  • pC calibrator
  • Transponder (needed when cable lengths are greater than 5 km)
  • HFCTs (High Frequency Current Transformers) (set of 2)
  • Coaxial cables

Applications

The QCM-C-PDP cable online PD measurement system can be successfully used for measuring partial discharge in cables with confidence. Used for low-cost, high performance periodic online and offline PD testing on HV insulating system of power cables and their terminations in transmission installations, power plants and large industrial consumers. The information gained may be used for condition based maintenance decisions.
