Profile:

KDDAC-30 is an integrated PD test system with wireless control, combining laser-triggered high-voltage switch and 100MHz sampling rate. It features portable design, full Chinese interface and automatic calibration, enabling efficient and accurate on-site cable testing.

Features:

  • Laser-triggered high-voltage switch with on-time 1μs and on-resistance <1Ω for stable oscillation wave output
  • Wireless/wired dual-control mode (IEEE 802.11a) for flexible on-site operation
  • PD positioning accuracy ≤1% of cable length (minimum resolution 2m) with 150kHz~45MHz automatic bandwidth adjustment
  • Built-in TDR function to measure cable length, joint position and wave speed accurately
  • Full Chinese software interface, supporting automatic/manual calibration (20pC~100nC, 12 gears)
  • Simultaneous measurement of PD signal, dielectric loss and cable capacitance for comprehensive insulation assessment
  • External safety control unit with emergency stop and lock switch for enhanced operational safety
