Advanced High-Voltage Measurement Solution

This upgraded 400pF model delivers superior measurement accuracy (<1% uncertainty) for 900kV impulse testing applications. The multistage distributed damping design ensures faithful waveform reproduction in compliance with GB311 standards for high-voltage test measurements.

Key Technical Enhancements

• Increased capacitance (400pF vs. standard 300pF) for improved signal-to-noise ratio

• Ultra-low measurement uncertainty <1% for precision applications

• Optimized non-inductive capacitor network with parallel low-voltage arm

• Industrial-grade polyurethane wheel base with locking stabilization

• Field-replaceable stainless steel top electrode
