【Abstract】 The active electronic current transducer is an important device used in power system for measurement, control and protection. The power supply for the high voltage unit of transducer is a problem unsolved in the past of application researches. Based on recent researches, this paper presents a new design of power supply, which combines the advantages of methods with CT and Li-ion battery. The new designs make the transducer run as normal during HV halt or under the condition of insufficient current state. The properties of the new power supply are high quality of the voltage, wide temperature range, and long operating life. Practicable is the new design of the power supply for the active electronic current transducer.更多还原
