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, provided there are two or more insulators between conductor and ground and at any voltage. It can also be used to test de-energized insulators prior to installation.
