Profile:

KDYD-LH is a PLC+touch screen controlled high voltage tracking tester, designed for 5-channel independent tests. It features precise liquid dropping, stable voltage output and multiple safety protections, auto-generating test reports for insulation material tracking resistance detection.

Features:

  • Precision plunger pump for stable and uniform contaminated liquid dropping with adjustable flow rate
  • Automatic voltage stabilization function, unaffected by power grid voltage fluctuations with small voltage drop
  • 5 independent test channels for high efficiency and strong comparability of test results
  • Built-in exhaust system to remove harmful gas generated by discharge in time
  • Multiple safety protections: self-locking, door interlock, zero start, overcurrent and overvoltage protection
  • PLC+touch screen control with humanized design, automatic test report generation after test
