Abstract
When the switches were operated, the transient overvoltage will be caused on the bus bar in substation. If the wide frequency model of the potential transformer (PT) or the coupling capacitor voltage transformer (CCVT) was acquired, the interference voltage in the secondary circuits caused by the transient overvoltage could be predicted. In the paper, a modified transfer function synthesis method is presented. After the transfer characteristic of the PT or CCVT is measured, the wide frequency model of the PT or CCVT can be set up with the synthesis method. The method is simple and effective
