Smart meter is an intelligent instrumentation whose core is the microprocessor application and network communication technology. Smart meter is getting the popularizing and applying at home and abroad. Except for having the basic function of the two-way measurement, Smart meter also has other various functions, for example, the point classification measurement, two-way communication, various control models, a variety of data transmission mode, preventing electricity-stolen. This paper introduces the working principle of the smart meter, expounds the application of zero line current transformer for smart meter, analyzes the actual connection mode of smart meter installation, proposes the problems should be paid attention to when the smart meter is installed, and the last gives the relevant solutions.
