Why Choose This Wide-Frequency Divider?

The LQHVF 200kV/9000pF represents the pinnacle of versatile high-voltage measurement technology. Its unprecedented 20-300Hz frequency range covers sub-synchronous testing (20-49Hz), power frequency (50/60Hz), and medium-frequency applications (up to 300Hz) in a single device. The 9000pF capacity provides exceptional signal-to-noise ratio in resonant test circuits, while the 2000:1 voltage ratio enables high-resolution measurements. With its 240kV withstand capability and ONAN cooling system, the divider maintains stability during demanding 60-minute tests. The removable corona rings and base optimize transport and storage, and the flexible connection system supports both single-stage and two-stage configurations. Certified to international standards including IEC 60060 and IEEE 4, this solution is ideal for testing laboratories, utility commissioning teams, and high-voltage equipment manufacturers.
