Introduction
In the realm of high-voltage testing, the 20kV/10kA Impulse Combination Wave Test System stands as a critical tool for evaluating the dielectric strength and surge resistance of electrical equipment. This system generates standardized lightning and switching impulses to simulate real-world transient overvoltage conditions. HVHIPOT, a leader in high-voltage test solutions, offers an advanced technical solution that combines precision, safety, and reliability for industrial applications.
Key Components of the Test System
1. Impulse Voltage Generator
The core of the system is a multi-stage Marx generator capable of producing 20kV impulses with a rise time of 1.2μs and a decay time of 50μs (for lightning impulses) or 250μs (for switching impulses). HVHIPOT’s design ensures minimal waveform oscillations (<±3%) and high energy efficiency.
2. Current Surge Module
The 10kA current surge component delivers an 8/20μs current wave, critical for testing surge protective devices (SPDs). The integrated current measurement system achieves ±1% accuracy using Rogowski coils or shunt resistors.
3. Control and Monitoring Unit
A touchscreen HMI allows operators to:
- Set waveform parameters (front time, tail time, polarity)
- Automate test sequences per IEC 61000-4-5
- Monitor real-time waveforms via built-in oscilloscope
