Vacuum tester

October 2010 Maintenance, Test & Measurement, Calibration

When a vacuum circuit breaker is commissioned or undergoes routine tests it is important to determine whether or not the vacuum in the vacuum bottle is intact before putting it back into operation. The Programma Vidar vacuum tester enables the user to check the integrity of the vacuum bottle quickly and conveniently by using the relationship between the flashover voltage and the pressure in the breaking chamber. A suitable test voltage is applied to the breaker and the result is displayed immediately.

The vacuum tester meets CE and EMC directives and operates on 115/230 VAC at 50/60 Hz. The instrument has six test voltages from 10 to 60 kV and a two-hand control and a high-voltage warning light enhances safety. A green light indicates approval of the breaking vacuum chamber, a red light indicates that the current has exceeded 0,3 mA and a yellow light indicates that the test was interrupted.
