Electrical discharge machining (debris) to be carried away and the insulating properties of the dielectric to be restored. Adding new liquid dielectric in the inter-electrode volume is commonly referred to as "flushing." Also, after a current flow, the difference of potential between the electrodes is restored to what it was before the breakdown, so that a new liquid dielectric breakdown can occur. The erosive effect of electrical discharges was first noted in 1770 by English physicist Joseph Priestley. Two Russian scientists, B. R. Lazarenko and N. I. Lazarenko, were tasked in 1943 to investigate ways of preventing the erosion of tungsten electrical contacts
Electrical Water Pageant the Main Street Electrical Parade at Disneyland, an oscillator swoop was heard during the music transitions in the Electrical Water Pageant. The 1972 to 1976 lineup of floats for the Electrical Water Pageant were: With the return of the Disneyland Main Street Electrical Parade in an updated form along with the brand new Walt Disney World Main Street Electrical Parade, a new version of Jean-Jacques Perry & Gershon Kingsley's "Baroque Hoedown" was created in 1977 to be used with both parades respectively featuring an updated rendition of Barque Hoedown recorded by Don Dorsey. To help distinguish the Electrical Water Pageant
