Innovative Multistage Design

This advanced voltage divider features a series-connected multistage configuration with two 300kV/800pF capacitor stages, delivering superior performance for 600kV impulse testing. The non-inductive construction ensures accurate waveform measurement without distortion.

• Dual-Stage HV Capacitors: 2×300kV/800pF units in series for 600kV operation

• Multistage Damping Resistors: Precisely distributed for optimal transient response

• Non-Inductive Low-Voltage Arm: Parallel-connected capacitors eliminate measurement artifacts

Mobile Test Platform

The rugged polyurethane wheel base with fixed brace provides exceptional mobility while maintaining stability during high-voltage tests:

• Heavy-Duty Metal Frame: High mechanical strength base withstands 600kV forces

• Polyurethane Wheels: Non-marking, high-durability movement system

• Field-Installable Top Electrode: Stainless steel corona protection for transport safety

• Flashover Prevention: Optimized electrode design minimizes abnormal discharges
