Product Overview
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.

Key Features
- 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.
