Problems solved by technology
Having a large number of cables not only increases cost and manufacturing complexity, but also makes it more difficult to change the machine to a different test sequence once the machine has been built
It also makes it difficult to pivot the upper contact assembly up and down as the large bundle of cables becomes very rigid

Embodiment Construction
[0011] see now figure 2 , the power distribution system 10 for a rotating capacitor electrical tester 12 according to an embodiment of the present invention takes advantage of the fact that the active stage 14 must always be in front of the passive stage 16 . In practice, the number of passive stations 16 following active station 14 may vary, from zero passive stations up to four passive stations. exist figure 2 Two passive stages 16a, 16b are shown for illustration purposes. Once the system has been built into a particular configuration, it is desirable to be able to change the number and sequence of active stations 14 and passive stations 16 relatively simply.
[0012] instead of having figure 1 Dedicated cables 18 from the power supply 20 to each of the passive stages 16a, 16b seen in figure 2 A passive station 16a, 16b according to an embodiment of the invention illustrated in receives its power from a separate conductor 22 from the station 14 or 16 immediately coun...

A power distribution system for a rotary capacitor electrical tester includes a power source, an active station having plurality of test channels powered by the power source through cables connected to one side an upper contact module of the active station, and an opposition side a lower contact module of the active station being connectable to a test measurement device. A separate additional cable conductor inlet is located on the active station for receiving power from the power source. The power supplied through the extra additional cable is passed through the upper contact module of the active station without connecting to test channel and presents a power conductor outlet interface to a passive station immediately adjacent to the active station in order to reduce the number of cablesrequired to connect between the power source and the various passive stations incorporated into the rotary capacitor electrical tester.
Description
technical field [0001] The present invention relates to a power distribution system for a group of test benches of a rotating capacitor electrical tester, and in particular to a power distribution system for indirectly powering a passive station through an active station located upstream of the passive station. Background technique [0002] Adding a test stand to a rotating capacitor electrical tester requires increasing the number of cables that must be routed to the upper contacts of the tester. Having a large number of cables not only increases cost and manufacturing complexity, but also makes it more difficult to change the machine to a different test sequence once the machine has been built. It also makes it difficult to pivot the upper contact assembly up and down because large bundles of cables become very rigid. [0003] For each track of each test station, there is a coaxial line connected to the power supply to provide the test voltage for that test channel. For ...
