一种基于新型电子式电流互感器直流电能表的研制
Development of a novel DC electricity meter based on new electronic current transformer
A DC electricity meter using for electric vehicle charging pile is developed; The performance parameters and working principle of the meter are introduced; The software and hardware circuits of the meter are designed; The error data and the power loss using new electronic current transformer and diverter under different loads are tested. From the experimental results and social survey analysis we can see: The accuracy of the DC electricity meter is superior to the traditional DC electricity meter；More importantly,It has a good economic prospect.
