The over-voltage protection device of the rotor is also called the jumper, which acts as the main protection for the rotor of the large generator and also plays the role of demagnetization. Correct and safe periodic inspection of the device is a prerequisite for normal operation of the generator.

After obtaining the utility model patent on August 13, 2014, the device was authorized in recent days after acceptance, preliminary examination, publication, and actual examination in accordance with the application approval procedure and time limit for the invention patent. The invention patent provides a test method for the performance test of the generator rotor over-voltage protection device, solves the technical problem that the generator rotor over-voltage protection device has no test equipment, and provides a simple method for testing the generator rotor over-voltage protection device. The convenient, safe, scientific, low-cost, easy-to-implement, widely-used test instrument fills the gap of the generator rotor over-voltage protection device without test equipment.

This patent for invention is a phased achievement of the ongoing research work of the Institute of Electrical Engineering in recent years, which further enhances the technical strength of the Institute of Electrical Engineering and provides technical support for the better service of power generation enterprises.
