The Megger VIDAR is a vacuum interrupter (VI) tester that enables the user 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. VIDAR units apply a suitable test voltage to a breaker and results are instantaneous. The VIDAR tester allows users to select among test voltages from 10 to 60kV DC. Once VIDAR completes a test, a green lamp will light up to indicate approval of the vacuum interrupter, a red lamp indicates the vacuum interrupter is defective. The rugged, lightweight, compact and portable VIDAR is ideal for field work and shop floor applications.
