Use of fluorocarbon gases to prevent arcover in DC capacitors
Abstract
The use of Fr-14 and Fr-116 to increase the margin arcover voltage in dry Mylar energy storage capacitors is investigated. It is found that pressurization of capacitors with Fr-14 results in a small increase in arcover voltage. However, pressurization with Fr-116 results in arcover voltages 1.5 to 2.5 times larger than obtained in air.
