MEGGER VIDAR | VACUUM INTERRUPTER TESTER
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.
- Tests the integrity of vacuum interrupters quickly, safely, and easily
- User-defined voltage selection
- Extensive voltage range
- Easy to operate. Follows ANSI/IEEE standardized DC test methods.
- Lightweight and portable
The VIDAR vacuum interrupter tester 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 vacuum interrupter.
A suitable test voltage (DC) is applied to the breaker and the result is known immediately. You can select test voltages from 10 to 60 kV DC and one of these voltages can be customized to your specifications when ordering. Reading the unit is also easy: if the interrupter is approved, a green light is shown, if it is defective, a red light is shown. It requires two-handed control and comes with a warning light that comes on if high voltage is detected, both of which enhance your safety.
The VIDAR vacuum interrupter tester is used to test the ability of the vacuum chamber to inhibit flashovers. It has been developed in close collaboration with leading manufacturers of vacuum circuit breakers. It is rugged, compact, weighs only about 7 kg (15 lbs), and is easy to use since vacuum chambers do not have to be dismounted for testing This makes the VIDAR ideal for use in the field or shop floor applications.

FEATURES AND BENEFITS
1. High voltage cable.
For connection of the test voltage and ground to the vacuum breaking chamber Note! The cable can have another color than yellow.
2. CANCEL lamp. Lights up when:
- The test interval has exceeded one minute.
- you try to conduct a one-minute test less than two minutes after the latest test.
- The HIGH-VOLTAGE indicator malfunctions.
3. HIGH-VOLTAGE warning lamp.
Shows that the high voltage is applied.
4. Test voltage selector.
10 to 60 kV DC. One of these voltages is customized and specified by the customer when ordering.
5. Protective earth (ground) terminal.
6. Large test clip connectors.
Provides for quicker connectionand a more efficient testing process
7. TEST Safety control knobs.
Both knobs must be turned simultaneously to apply high voltage to the test object.
8. ACCEPTABLE green lamp.
Lights up when the breaking test result is positive.
9. DEFECTIVE red lamp.
Lights up when the breaking chamber test result is negative when the flashover threshold voltage is too low.
10. I / O Power ON/OFF
11. Mains inlet
12. Slide switch
for mains,115 V / 230 VAC 70 VA, 50 -60 Hz
The VIDAR vacuum interrupter tester is used to test the abilityof the vacuum chamber to inhibit flashovers. The rugged,lightweight, compact and portable VIDAR is ideal for field workand shop floor applications.The internal pressure of vacuum chambers do not last forever.Leakage starts after years or decades and the interruptersfill with air making the breaker unreliable. In most cases, theleakage process is rapid once it has started. In addition toleakage, dirt on the poles and on the exterior surface of thevacuum chamber can make it unsafe during operation. Themechanics of the breaker can become misaligned so that thedistance between the poles no longer is adequate.
