Vacuum interrupter tester-VIDAR

Adiradh offers  Vacuum interrupter tester VIDAR that enables to check the integrity of the vacuum circuit breaker/interrupter quickly and conveniently by means of the known relationship between the flashover voltage and the vacuum interrupter. In Vacuum interrupter  tester Megger Vidar  test voltage (DC) is applied to the breaker, and the result is known immediately.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.The accepted way to test the vacuum integrity has always been through a voltage withstand test. For field tests DC test is preferred due to the weight and size of the instruments.

Vacuum Interrupter Tester VIDAR

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. Vacuum Interrupter Tester uses high voltage DC to test the integrity of vacuum breakers.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.VIDAR has been developed in close collaboration with leading manufacturers of vacuum circuit breakers. It weighs only about 7 kg 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 of  Megger VIDAR-vacuum interrupter tester

The 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 field work and shop floor applications.The internal pressure of vacuum chambers 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 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

The DC voltage applied for an equivalent test is equal in magnitude to the peak of the AC voltage required. The DC method is described in IEEE C37.20.3 standard. For guidance on test voltage refer to IEC 62271-1 and IEEE C37.06 standards
