Intelligent surge generatorTest project source
① Lightning strikes a high-voltage system once or strikes a low-voltage power supply system line or communication line twice;
② Discharge between clouds in the sky or between clouds and the earth can cause earth currents to enter the ground wire;
③ Switching operations such as capacitor bank switching, thyristor on-off, equipment and system ground short circuits, and arc faults can also generate transient overvoltage or overcurrent on the power grid;
④ Surge is in the form of pulses, with a wavefront time of microseconds, a pulse half peak time ranging from tens of microseconds to hundreds of microseconds, and a pulse amplitude ranging from hundreds of volts to tens of thousands of volts. It is a high-energy disturbance.

Test requirements
① Equipment connected to the power feeder uses a 4/300 μ s waveform;
② Equipment connected to signal transmission lines, using a 10/700 μ s waveform;
③ Equipment connected to steel, using a 10/200 μ s waveform;
④ For equipment that is prone to counterattack due to rising ground potential caused by lightning strikes on the ground, a direct lightning counterattack simulation test should be conducted using a 1.2/50 μ s waveform;
⑤ The lightning protection device for the signal transmission line of outdoor signal equipment uses an 8/20 μ s impulse current waveform
