At present

the improvement of the intelligent level of power grid has a higher demand for the intelligence and efficiency of high voltage test. In order to improve the power supply and the efficiency of high voltage test

an intelligent magnetically controlled resonant high-voltage test system is proposed. The test system integrates voltage boost

compensation and tunning

with such features as smooth and continuous boost regulation as well as compact structure and can be used in power frequency withstand voltage test. This paper describes the structure and basic principle of the system

establishes the simulation model of the test system

and verifies the correctness of the system principle by studying the no-load and load operation character is tics by simulation.
