Abstract

The leakage current of insulator surface varies with the accumulation of pollution

which is an implementable and effective method.This paper proposes a portable leakage current monitoring system for site outer insulation studies.Difference mode has been applied in this system for common mode signal re-duction.The synchronous sampling rate can reach 20 k S/s

which can record full information in the leakage current data.Resistor sensor has been applied in this system

which has a good anti-electromagnetic interference performance.This system has a wide measuring range from 0.1 m A to 5 A

relative error can be controlled within 2%.Applied voltage values on the insulator can also been measured through this sys-tem when correlating with a voltage divider.LABVIEW has been applied for software platform building of the system

which is easy to operate

rich in functions and extendible.Features of this system are light weight

small volume

economic and convenient to implement.This system can fit varies site applications for research institutes.
