An Arc Fault Current Interrupter Based On Wavelet Transformation

摘要

In real life, arc fault circuit interrupter plays a very important role to prevent the arc fault from fire about protecting the circuit. This article mainly introduces the types of arc,and the main purpose of designing this new type interrupter. The paper tells that it knows about the basic principle of wavelet transformation and use the wavelet tested data to be analyzed.The paper uses the window moving method to summarizes how to judge the basis of arc fault.Some kinds of loads are suitable and some are not.The paper also designs arc detection flow chart. It applies for effective basis for further.
