Product BrochureProduct Details:

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 is intact before putting it back into operation.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 integrity of the vacuum interrupter. A suitable test voltage (DC) is applied to the interrupter, and the result is known immediately. VIDAR permits you to select among test voltages from 10 to 60 kV DC. One of these voltages is customized and specified by the customer when ordering. A green lamp indicates the approval of the interrupter. A red lamp indicates that it is defective. Two-hand control and a high-voltage warning lamp enhance safety.VIDAR has been developed in close collaboration with leading manufacturers of vacuum circuit breakers. It weighs only about 7 kg (15 lbs), and it is easy to use since vacuum chambers do not have to be dismounted for testing. VIDAR is therefore ideal for use in the field or shop floor applications. applications VIDAR vacuum interrupter tester is used to test the ability of the vacuum chamber to inhibit flashovers. The rugged, lightweight, compact and portable VIDAR is ideal for fieldwork and shop floor applications. The internal pressure of vacuum chambers 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 vacuum chamber 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.
