So, recently went onto a job to perform VLF testing of 2 sets of 35kV cables, when the customer threw a curve ball at me to test the 35kV breakers. I had no ac hipot to perform vacuum bottle integrity and withstand test. Our management does not want us to test with DC on vacuum bottles, as there is documentation that dc can damage vacuum bottles (haven't .Vacuum Bottle Insulation Integrity Test - HighTest Technology - Transformer Test Equipment ~ Circuit Breaker Timer, Winding Resistance, Transformer Ratio You can see one of high voltage Vacuum Interrupter Tester as below pic from 10 to 60 kV DC from Megger company: DC Vacuum Interrupter Tester. The leak-rate test (MAC test):This test is based on the Penning Discharge Principle which is named after Frans Michael Penning (1894-1953). Penning showed that when a high voltage is applied to open .High voltage testing of vacuum bottles should be performed using AC voltage. DC voltage testing is not recommendby ed most bottle manufacturers and forbidden by some. Like on most high voltage electrical apparatus in a substation, . verify the AC integrity of your equipment. The item either holds the AC voltage or doesn’t. 5/25/17.
At first I was not sure if the vacuum bottle integrity test is a factory test or field acceptance test, reading from the descrptive of the test. Thanks for verifying this. RE: Vacuum Bottle integrity test dpmac (Electrical) 14 Jul 08 07:10.

The Hipotronics model 7BT60 is a piece of portable 60 kV AC (Center Tapped) Dielectric testing equipment designed to test the integrity of vacuum interrupters in switchgear. The output (current limited to 10 mA) is programmed to raise voltage at a preset rate to the desired test level.LIGHTHOUSE technology detects closure integrity through the exchange of gas through container defects. From products stored at room temperature down to cryogenic conditions, LIGHTHOUSE analyzers enable reliable container closure integrity testing (CCIT) across a diverse array of packages and products throughout the product life cycle.
Checking integrity of vacuum interrupters
• Vacuum interrupters installed in this period have far exceeded their manufacturer specified life expectancy. • Failure of a vacuum interrupter could result in unnecessary downtime and damage to surrounding equipment. Traditional testing methods • Vacuum integrity Pass or Fail test using high voltage ac test set.The best leak testing machine is Vacuum Leak tester for PET Bottles. The testing instrument efficiently measures the leak integrity of PET Bottles that can be examined with the help of high-pressure vacuum and ensures that the test sample is free from all types of leakage.
Leak testing plays a crucial role in ensuring the integrity of packaged products, particularly in industries like food and beverage, pharmaceuticals, and cosmetics. A compromised seal can lead to: . Ensuring .10.4.2 Vacuum bottle integrity tests: AC or DC Hipot testing should be performed across the open contacts in strict accordance with manufacturer’s recommended test voltage. The test equipment should have a full wave rectification. 10.4.3 Other testing: All other testing such as insulation testing, micro-ohm tests and timing shouldHIPOTRONICS' model 7BT60 is a piece of portable 60 kV AC (center tapped) dielectric testing equipment designed to test the integrity of vacuum interrupters in switchgear.
