When a vacuum circuit breaker is commissioned or undergoes routine tests, it is very important to be able to ascertain whether or not the Vacuum Interrupter (VI) is intact before putting it back into operation.

The VI in vacuum breakers do 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. The Megger VIDAR (introduced in 1985 as the Programma Vidar), uses high voltage DC to test the integrity of vacuum breakers.

The Megger VIDAR enables you to check the integrity of the vacuum interrupter quickly and conveniently by means of the known relationship between the flashover voltage and the vacuum interrupter. A suitable test voltage (DC) is applied to the breaker, and the result is known immediately.

The VIDAR permits you to select among test voltages from 10 to 60 kV DC. One of these voltages is customised and specified by the customer when ordering A green lamp indicates approval of the VI. A red lamp indicates that it is defective. Two-hand control and a high-voltage warning lamp enhances safety.
