3. DC HiPot testing is unreliable due to the occurrence of a phenomenon known as Cathode Ray Tube Effect This occurs when one contact of the vacuum bottle has a deformity such as a burr or deposit while the other contact remains flat and true This sets up leakage currents which flow from a small surface to a large surface in one direction and vice versa when the polarity of the tester is changed The resultant current is large in one direction which would indicate incorrectly a faulty vacuum bottle At best DC testing will verify vacuum integrity if both contact surfaces are perfectly smooth It will not however give any indication of the degree of vacuum since the contact surface can feasibly change with each operation of the vacuum contactor AC testing on the other hand will provide reliable vacuum integrity indication As well the degree of vacuum within the bottle can be determined by comparing initial test results to the present readings Increases in leakage current indicates a reduction in vacuum within the vacuum bottle For these reasons Rockwell Automation recommends AC testing as the only reliable method of testing vacuum bottles Using a 1000 volt Megger the resistance from phase to phase or phase to ground shall be greater than 500 megohms 1502 UM051E EN P June 2013 Chapter 3 Installation Mounting The Allen Bradley vacuum contactor is normally fixed mounted bolted down in the enclosure of the controll
