Insulator Tester

The Hi-Test^® IT-4 Insulator Tester detects non-visible insulator failures before they cause operations difficulties or safety threats to line crews. The Insulator Tester can be used as a routine maintenance tool to test insulators quickly, safely and reliably. It can be applied to any in-service transmission or distribution insulator and at any voltage, provided there are two or more insulators between conductor and ground. It can also be used to test de-energized insulators prior to installation.

IT-4绝缘子测试仪 
IT-4绝缘子测试仪可以在线检测通电状态下的绝缘子，也可以检测未安装或待检查的不通电的绝缘子。测试仪前端有两根柔性金属探头，探头间加载一个高压直流电源，该直流电源加载到绝缘子两端的连接金件，从而检测绝缘子的绝缘性能，并通过面板上的LED指示提示用户当前绝缘子是否状态良好。

产品特点： 
检测通电状态或未通电的绝缘子 
声光报警提示绝缘子绝缘性能缺陷 
可检测各类陶瓷或玻璃材质的绝缘子 
壳体耐压高达69KV（相间），可用于任意电压线路中单个绝缘子的检测 
绝缘子中间状态提示 
内置电源电流限定，避免人身触摸伤害 
可通过市电或车载电源充电 
快速充电，满电情况下可检测大约120次（非短接）
