Ultra-High-Ratio Measurement for Critical HV Applications

The LQHVF 260kV/3000pF sets new standards in high-voltage measurement with its groundbreaking 6000:1 voltage ratio - the highest precision available for commercial 260kV systems. Engineered for research laboratories and precision testing facilities, this solution delivers:

• Unprecedented 6000:1 ratio for microvolt-level resolution

• 286kV insulation withstand (110% rated voltage)

• Broad 20-300Hz frequency coverage for resonant systems

• Scalable architecture for voltages up to 520kV

Breakthrough Measurement Resolution

With 6000:1 ratio, 260kV measurements resolve to 43.3V - enabling use with standard laboratory instruments for unprecedented precision.

Operational Advantages

• Unmatched Resolution: 43.3V equivalent at 260kV enables micro-discharge detection

• Frequency Flexibility: Constant accuracy across 20-300Hz range

• Thermal Stability: ONAN cooling maintains ≤0.1% ratio drift during 1-hour tests

• Scalable Architecture: Single (260kV) or series (520kV) configurations

"The 6000:1 ratio provides resolution previously impossible at 260kV - we've detected partial discharges 50% smaller than with conventional dividers."
