Product Introduction

AI-6103 is used to measure the leakage current of Metal Oxide Arrester (MOA). The main datum is resistive current. With witch the ageing or inside damp of the MOA can be evaluated. AI-6103 meets requirement for site test and laboratory test.
One AI-6103 has two functions:
1、To test resistive current with a reference voltage, normally from secondary of potential transformer (PT). This method is quite common, and can offer the best accuracy.
2、To test resistance current with a reference electrical field. A metal plate is mounted at the base of MOA of ΦB to induct the electrical field which contains the phase information of the BUS voltage. This method is simple, and can offer good accuracy.
AI-6103 is easy to operate, rich in readings. The set is applied with rechargeable battery, calendar clock, and micro printer, memory for 100 groups of test data, and RS232 port to transmit the data to computer.

Product Features

▪The fundamental resistance current, which we firstly introduced to this tester, is widely accepted now, so the data is in common use.

▪Make test easily and quickly.

▪All calculations are based on standard theory so the tester can be calibrated in laboratory.

▪Full digital processing. Embedded microprocessor enables the tester to reach high accuracy and stability.

▪Two isolated channels to input the leakage current and reference signals witch eliminate the magnetic interference.

▪Big LCD with backlight. Four keys operate the menu.
