Hipot Impulse Voltage Generator Lightning Impulse Voltage Testing Machine

The Hipot Impulse Voltage Generator is a high-performance lightning impulse voltage test system engineered to simulate lightning strike conditions on electrical equipment. Designed in strict compliance with IEC 60060-1 and IEC 60060-2 international standards, this system generates standard 1.2/50µs lightning impulse waveforms and chopped waveforms, enabling manufacturers, utility operators, and research institutions to evaluate the dielectric strength and insulation integrity of high-voltage apparatus.

Widely applied across power generation, transmission, and distribution sectors, this impulse voltage test system is the essential quality assurance instrument for GIS (Gas-Insulated Switchgear), power cables, insulators, air gaps, bushings, transformers, and other critical high-voltage components. By verifying lightning impulse withstand capability before deployment, it helps prevent catastrophic in-service failures and ensures grid reliability.

With a nominal output of ±300kV, modular 3-stage design, and fully computer-controlled measurement and control system, the Impulse Voltage Generator delivers the precision, repeatability, and safety that modern high-voltage testing laboratories demand.

• Standard Lightning Waveform Compliance: Generates 1.2/±30µs front / 50± 20% µs tail standard lightning impulse waveform per IEC 60060-1, with waveform efficiency ≥90% (load capacitance ≤1000pF) and ≥85% (load capacitance ≤2000pF).
• Chopped Waveform Capability: Supports standard chopped waveform generation for switching surge and chopped impulse testing applications.
• Computer-Controlled Measurement & Control System: Fully automated charging, triggering, and waveform acquisition via integrated PC-based control software with real-time waveform display and data storage.
• Precision Charging Control: Constant-current charging with voltage instability ≤±1%, charging voltage deviation ≤±1%, and adjustment accuracy of ±1%, ensuring highly repeatable test results.
• Low Synchronization Error: Trigger synchronization error rate ≤1%, critical for multi-stage generator reliable series operation.
• Modular Multi-Stage Architecture: 3-stage design with ±100kV per stage, allowing future voltage upgrades by adding stages.
• Robust Continuous Operation: Supports continuous charge/discharge cycling at 120s intervals above 2/3 rated voltage and 60s intervals below 2/3 rated voltage.
• Adjustable Waveform Resistors: Interchangeable front and tail resistors allow waveform tuning based on test load characteristics.
• Minimum Output Voltage ≥15% Un: Enables low-voltage calibration and sensitivity verification across the full range.
