Designation and application of an on-line monitoring insulator leakage current system

A remote GSM SMS system signed and produced, the composition of on-line measuring insulator leakage current was deand the theory of which were described. The designation methods of the monitoring unit and the expert software were outlined in detail. The experimental results show that the validity of current collector is greater than 97% and the measurement error of the leakage current is less than 1%. The running results show that the leakage current, the pulse current and the humidity etc. can be precisely measured by the on-line monitoring system, and that the insulation status of the running insulators was clear.
