1. Product Description
400kV Lightning Impulse Generator for High Voltage Insulation Testing
The 400kV Lightning Impulse Generator is designed to provide reliable impulse voltage testing for evaluating the dielectric strength of power system components. During actual operation, electrical equipment may be exposed to lightning surges and transient overvoltage conditions. This test system helps manufacturers and laboratories verify insulation performance before equipment is connected to the grid.
Featuring a modular impulse voltage generation structure, the system uses multiple stages of impulse energy storage units to achieve high voltage output. The optimized design ensures stable charging, accurate discharge control, and repeatable test results. It is an ideal testing solution for organizations requiring professional high voltage insulation assessment.
The generator produces a standard 1.2/50μs lightning impulse waveform, allowing engineers to simulate lightning impact and analyze the response of electrical insulation systems. Combined with digital monitoring technology, operators can easily manage test procedures and obtain accurate measurement data.
This 400kV Lightning Impulse Generator is suitable for power equipment manufacturers, independent testing laboratories, and research institutions. It helps improve product reliability, verify insulation design, and reduce potential failures caused by external overvoltage.
