Programma VIDAR enables you to check the integrity of the vacuum bottle quickly and conveniently by means of the known relationship between the flashover voltage and the underpressure in the breaking chamber. The test voltage (DC) is applied to the breaker, and the result is displayed immediately. The use of DC is well proven for many years.

The unit permits you to select among six test voltages from 10 to 60kV DC. One of these voltages can be customized and specified by the customer upon ordering. VIDAR has been developed in close collaboration with leading manufacturers of vacuum circuit breakers.
