The AC high potential test is great for testing insulation reliability on cables and other electrical components. Stressing the insulator allows the technician to determine if the sample can withstand electrical variations above normal rating during operation. One of the testers you might want to check out is the Adwel HVA40-10.
The Adwel HVA40-10 AC hipot not only tests cables, this tester is also designed for vacuum interrupter testing. It can provide test voltages up to 40 kiloVolts which is required by the ANSI/IEEE C37.60 and C37.61 standards. This test voltage can be finely adjusted and is monitored at the output. The HVA40-10 has a solid-state disconnection circuit that interrupts the test voltage in case of an insulation breakdown or flash over. It also has several safety features like a dead-man switch requiring two hands to activate the device. It has an interlock switch to protect the user from the test voltage during start up.
