Profile:

KDXZ-22/22 110kV/220kV is a variable frequency series resonant test device. It uses multi-stage reactors (series/parallel) and a voltage divider for measurement/compensation, achieving resonance at 30–300Hz to complete AC withstand voltage tests for 110kV/220kV electrical equipment.

Features:

  • Displays real-time frequency curve
  • Provides overcurrent and flashover discharge protection
  • Equipped with touch LCD color screen
  • Supports multiple operating modes
  • Performs automatic frequency exchange calculation
  • Adopts modular reactor design for flexible voltage matching
