Abstract：Online-testing in current of shifiting resistance is applied to ensure the integrated circuit in secondary side of current transformer basing on the theory of the shunt resistance,what could prevent open circuit. the suitable resistance value is counted because of the statistics in many actual values. the anticipation device for open circuit in secondary side of current is developed considering some important safety factors. the tests results show ideal effect of the device in the anticipation of open circuit in secondary side of current transformer
