Generating High Voltage DC with Cockcroft-Walton Voltage Multiplier for Testing Locally Assemble Electric Field Sensor

This paper describes the construction of a high voltage DC generator using single-phase transformer and Cockcroft-Walton voltage multiplier. The aim is to simulate high voltage DC for simulating electric field produced before a lightning strike near the ground. Lower AC voltage is step up to high AC voltage using a neon transformer. The AC voltage is then converted into high DC voltage using variable stages of Cockcroft-Walton voltage multiplier. The generator HVDC is connected to the adjustable parallel plate to ground. Variable stages of Cockcroft-Walton voltage multiplier produce high voltage magnitude proportional to each stage of it. The electric field generated from high voltage DC can also be varied depending on the distance between DC output plate and ground. The application of high voltage DC in generating electric field useful in testing locally assembled Electric Field Sensor.
