Withstand Voltage Test of Insulation Tools Fawu.He，Professor， Electrical Engineering Guangzhou Railway Polytechnic，China Withstand Voltage Test of Insulation Tools Insulation Tool Cognition 01 Why are insulation tools tested? How to judge the qualified standard of insulation tools? 1. The Problem to Import 35kV Insulating Boots 10KV Insulated Gloves 2. Auxiliary Insulation Tool Insulation Tool Cognition 01 35kV Insulating Boots 10KV Insulated Gloves 2. Auxiliary Insulation Tool Insulation Tool Cognition 01 If there is only one pair of gloves and insulated shoes on site, you can only choose one. What would you choose? 1.Test for defects that can be found Measuring Period and Standard of Auxiliary Insulation Tools 02 Method of Measuring with Auxiliary Insulation Tools 02 2. Eligibility Criteria ID Name Voltage Level(kV) Detection Cycle AC Withstand Voltage(kV) Time(min) Leakage Current(mA) 1 Insulation Rod 6～10 once a year 44     35～154 Four times the phase voltage 220 Triple line voltage 2 Insulated Gloves high voltage once six months 8 1 ≤9 low voltage 2.51 ≤2.5 3 Rubber Insulated Boots high voltage once six months 15 1 ≤7.5 4 Insulation Clamp 35KV and below once a year Triple line voltage 5   110 260 220 440 1. The Problem to Import Method of Measuring with Auxiliary Insulation Tools 03 How to Operate Auxiliary Insulation Tools Against Voltage? Method of Measuring with Auxiliary Insulation Tools 03 2.Schematic Diagram of Withstand Voltage Device Insulating shoes and Gloves Insulation Barrels Insulating Base Method of Measuring with Auxiliary Insulation Tools 03 3. The Judgment Standard Insulated shoes:Pressure to rated test voltage, no discharge within 60 seconds, current less than 7.5mA is qualified. Insulation gloves:Pressure to rated test voltage, no discharge within 60 seconds, current less than 9mA is qualified. Different voltage values should be applied according to different specifications of shoes and gloves. 1. Test notes Precautions for Measurement of
