The Impulse Voltage Generator provides a controlled way to reproduce these extreme transient conditions in the laboratory. By applying standardized impulse voltages, it helps engineers verify the insulation withstand strength and protective performance of high-voltage electrical equipment.
From transformers and GIS to switchgear, bushings, insulators, cables, CT/PTs and surge arresters, the system enables reliable impulse testing before equipment reaches the field.
One system covers a wide range of impulse testing requirements. It can generate lightning impulse, switching impulse, chopped lightning impulse, oscillating lightning impulse, oscillating switching impulse, chopped impulse for line insulators, chopped impulse for composite insulators, and induced operating impulse for transformers. The waveform performance is designed in accordance with applicable GB and IEC standards, supporting comprehensive high-voltage insulation testing.
The generator is supplied as a complete test system with coordinated components and supporting equipment. A wide selection of voltage levels and configurations makes it easier to match different test objects, laboratory requirements, and project capacities.
High-capacity test objects can significantly affect impulse waveform quality. With a low-inductance circuit design combined with damping and filtering technologies, the system maintains stable and compliant impulse waveforms even when testing demanding high-capacitance loads.
Optimized circuit design helps improve the utilization of the generated impulse voltage, enabling more effective energy delivery to the test object and supporting demanding high-voltage *testing applications.
Waveform parameters can be adjusted conveniently to meet different test requirements. Reliable synchronization and stable triggering ensure consistent impulse generation and repeatable test performance.
An automatic constant-current charging system provides precise and stable charging control. Strong resistance to electrical interference helps maintain reliable operation in complex testing environments.
