PD-TaD 80 Portable PD diagnostics system

The PD-TaD 80 portable PD diagnostics system is used in combination with a BAUR VLF HV generator for carrying out:
  • Partial discharge testing and location
  • VLF cable testing with parallel partial discharge testing
  • Dissipation factor measurement
Manufactory: BAUR (Austria).

Description

With the partial discharge testing and the dissipation factor measurement, two effective and proven methods for evaluating the ageing condition of medium-voltage cables and cable accessories have been combined in a single compact and portable device. The result is comprehensive one-step cable diagnostics: early detection and localisation of weak points through a PD measurement, in addition to the evaluation of dielectric ageing based on the dissipation factor values.

Light, robust and portable: PD-TaD is ideal for integration in cable test vans and, in combination with PHG portable, is also suitable for mobile use in the field.
Features
  • Partial discharge measurement and calibration of the measurement setup according to IEC 60270
  • At 21 kg, the lightest and most compact PD measuring device up to 80 kVpeak in the market
  • Excellent precision thanks to high coupling capacitance (8 nF) and sensitivity (≤ 1 pC)
  • Coupling capacitor incl. measurement impedance and PD measuring unit in one device
  • Easy test setup: identical test setup for partial discharge testing and dissipation factor measurement
  • Integrated filter for suppressing noise signals
  • Stable data transmission and power supply via Power over Ethernet (PoE); no batteries needed
  • Excellent noise suppression due to compact structure, galvanic isolation between PD measuring unit and laptop, central power supply
  • Integrated device for detecting leakage currents for dissipation factor measurement
  • Easy, menu-driven operation
  • Time and cost saving for onsite measurement
  • For integration into cable test vans
