This video is part of a series of experiments I’ve done and is detailed on my site:
This video shows my new HV MOT Power Supply and with it some experiments using a magnetic field to blow out the arc.
I show the effect with and without a magnetic field on standard HV AC discharges and a half-wave doubler discharge.
The half-wave circuit is kind of non-ideal because it’s sort of self extinguishing since the current is intermittent. The idea for using this would be to interrupt a constant DC current, but it shows the concept of the magnetic quench. And the principals here can easily be extended for DC or other waveforms.
In semiconductor testing, contactor can also refer to the specialised socket that connects the device under test.
In process industries a contactor is a vessel where two streams interact, for example, air and liquid. See Gas-liquid contactor.
