The dielectric fluid is nonconductive.
Well into the 1970s, polychlorinated biphenyls (PCBs) were often used as a dielectric fluid since they are not flammable.
Then we drain off the dielectric fluid, and get one billion three hundred million volts' charge into a condenser of only one hundred micro-microfarads.
It's usually a dielectric fluid, chosen for chemical compatibility with the other materials present.
The probe is filled with a dielectric fluid.
The Pyramid's blood was dielectric fluid.
It is also used as a hydraulic fluid and as a dielectric fluid in capacitors.
PCB's, polychlorinated biphenyls, were used until the late 1970's as a dielectric fluid in capacitors of large appliances, known as white goods.
They failed in this task but found that the erosion was more precisely controlled if the electrodes were immersed in a dielectric fluid.
A longer off time, for example, allows the flushing of dielectric fluid through a nozzle to clean out the eroded debris, thereby avoiding a short circuit.
