Equipment Overview
This set of multi-component waveform automatic lightning impulse current generator test device can be used for the lightning protection test of the aircraft, the aircraft's partial cabins or the engine components, and determine the actual induction level and transient waveforms on the aircraft electrical system cables. Determine or verify the transient control level and equipment transient design level related to lightning protection. The generator can also be used to test the non-electrical system conductors of the fuel system (such as control cables, fuel, hydraulic, pneumatic lines and structural parts) or system effects.
The system output D component peak value 100kA, T1≤30μS, T2≤500μS (exponential waveform or oscillating waveform).

Main Components
Body Sector Structure
The body capacitor adopts a sector structure, capacitor is placed vertically, and bottom is connected and fixed;
The body capacitor adopts a fan-shaped centripetal symmetrical structure to ensure that each group of capacitors is at the same distance from the discharge gap to ensure the uniformity of the discharge current to the greatest extent. In long-term use, such a structural design can ensure the uniform life of the capacitor, thereby prolonging the life of the device.
Capacitors can be operated in a single group or in parallel, and it is more convenient to switch the circuit manually. Each group of capacitors are connected in series with resistors during the discharge process, which can ensure the safe operation of the capacitors.
