Abstract

The invention discloses a system and method for calibrating a direct-current synthetic electric field measuring device, and belongs to the technical field of electromagnetic measurement and calibration. The system comprises a program-controlled direct-current power supply V1, a program-controlled direct-current power supply V2, a program-controlled direct-current power supply V3, a corona inception wire, a metal net 1, a metal net 2, a parallel metal plate and an ampere meter. The remote direct-current power supply V1 is connected with the corona inception wire, the remote direct-current powersupply V2 is connected with the metal net 1, and the program-controlled direct-current power supply V3 is connected with the metal net 2; wherein the remote direct-current power supply V1 is connected with the corona inception wire, the remote direct-current power supply V2 is connected with the metal net 1 and the program-controlled direct-current power supply V3 is connected with the metal net2 in parallel, the metal net 2 is connected with the parallel metal plate in parallel, and the parallel metal plate is connected with the calibration direct-current synthetic electric field measuringdevice and the ammeter. According to the invention, automatic pressurization of the polar plate of the direct-current synthetic electric field measuring device, automatic control of saturation of space charges and reading of data of the direct-current synthetic electric field measuring device to be calibrated can be realized through the automatic control system.
