Product Overview
The Impulse Voltage Generator provides a controlled and repeatable method for assessing the dielectric strength and surge withstand capability of high-voltage electrical equipment. By reproducing transient overvoltage conditions similar to those caused by lightning strikes and switching operations, it helps engineers identify insulation weaknesses and verify the reliability of electrical products.
The system is widely applicable in power utilities, electrical equipment manufacturing, testing laboratories, and high-voltage research facilities, supporting product development, quality verification, and type testing.
Highlight
Eight Impulse Waveform Modes One system supports eight commonly required impulse waveform configurations: lightning impulse, switching impulse, chopped lightning impulse, oscillating lightning impulse, oscillating switching impulse, chopped impulse for line insulators, chopped impulse for composite insulators, and transformer induced operating impulse. The system is designed around applicable GB and IEC standards, providing a versatile platform for high-voltage impulse testing.
Ready-to-Use Integrated Configuration The generator is supplied as a coordinated complete system, with the major charging, impulse generation, control, and measurement components properly matched. Different voltage classes can be selected to suit various test objects and laboratory capacities.
Reliable Output for High-Capacitance Test Objects The low-inductance discharge circuit is combined with optimized damping and filtering techniques to control waveform distortion. Even when connected to high-capacitance or large-capacity test loads, the system can maintain the required impulse waveform characteristics.
Efficient High-Voltage Energy Transfer The circuit architecture is optimized to make effective use of the stored energy during impulse generation, supporting efficient high-voltage output and stable testing performance.
Fast Setup & Stable Triggering Flexible waveform adjustment simplifies test preparation, while accurate synchronization and dependable triggering ensure consistent impulse generation and repeatable test conditions.
Automated Charging with Strong EMI Resistance Constant-current charging technology enables automatic charging management and improves charging stability. The control system is designed with strong resistance to electromagnetic interference for dependable operation in demanding high-voltage laboratory environments.
