The VIDAR vacuum tester is used to test the ability of the Vacuum Interrupter (VI) in a vacuum circuit to inhibit flashover. The rugged, lightweight, compact and portable VIDAR is ideal for field work and shop floor applications.
The VI in vacuum breakers does not last forever. Leakage starts after years or decades and the interrupters fill with air making the breaker unreliable. In most cases, the leakage process is rapid once it has started. In addition to leakage, dirt on the poles and on the exterior surface of the interrupter can make it unsafe during operation. The mechanics of the breaker can become misaligned so that the distance between the poles no longer is adequate.
VIDAR uses high voltage DC to test the integrity of vacuum breakers.
