Abstract

A kind of measuring system designed for the measurement of lightning return stroke currents under 50 kA, which is composed of current transformers, optical isolation system, data acquisition card and industrial computer, is described. Test results show that the current transformers and the optical isolation system have good stability. Moreover, primary research on remote transmission of the data is done. A wavelet-based compression arithmetic is designed, which is suitable for the data compression, greatly improving the speed of the data transmission.
