“…When the current break at the peak of the exciting current, then (3) If the transformer didn't install any overvoltage restrain device, for the primary side capacitance to ground of the transformer is only 13.3nF, we could know that the primary side will produce a high amplitude overvoltage to ground by formula (3).…”

“…Most of those energy-intensive enterprises are using electric arc furnace, which would cause hidden troubles to the grid, such as line trips, equipment damages and overvoltage accidents. Among this, the overvoltage accident caused by using the vacuum breaker to cut off the arc furnace transformers is one of the most serious problems [1][2][3][4][5][6][7][8][9][10][11][12][13] .…”

“…Authors of [1] propose a way based on raise the insulation level of the transformer winding, and provide the adjustment range of the insulation level of the 35kV transformer winding. [2][3] restrains the overvoltage by MOV and resistance capacitance absorbing device and puts forward the principle to selecting the arrester model. Besides, it solves the matching problems of the resistance and capacitance parameters.…”

In the process of power system operation, it is normal to interrupt no load transformer, reactor and no load motor. Switching those inductive loads will give rise to high amplitude overvoltage. With the example of a steel mill's refining furnace transformer, this paper covers the basic principle of the overvoltage formation, introduces the advantages and disadvantages of the resistance-capacitance absorbing device and rectifier bridge device. On base of the above analysis, this paper puts forward a mixed device to suppress overvoltage of interrupting no load transformer. Moreover, simulation has been worked with ATP-EMTP, the results show that the device can greatly reduce the overvoltage and improve the reliability of the system. At last, the effectiveness and feasibility of the presented device are verified by the experiment..
