Electrostatic Discharge Simulator with Positive or Negative Voltage of 300kV

The requirements of the electrostatic discharge (ESD) simulator for the helicopter replenishment in air on the American National military standard MIL-STD-331 is presented simply. According to the above requirements, the ESD simulator with positive or negative polarity and voltage amplitude from 10 kV to 300 kV is developed. The novel feature of the ESD simulator is that the operation of the high-voltage closing switch of ESDS with the voltage amplitude from 10 to 300 kV is realized by controlling the movement of the high voltage electrode with PLC elements and solids-state relays. The configuration, simulating results and typical experimental waveforms on various sorts of loads of inductive, capacitive and 100 ohms cases are presented in the paper.
