To present the design and construction of a transformer oil AC dielectric test set. Electronic circuits are used for increasing voltage during testing to determine a transformer oil AC dielectric strength and recording this value. The pocess for this test is set to be an automatically control. Otherwise, serial communication port is offered for linking to computer for controlling, graphic displaying, data storage and printing out by computer software. The performance of this testing set is satisfactory
