ABSTRACT:
In apparatus for the high frequency voltage testing of insulation on conductors, a display technique is disclosed in which a plurality of insulated conductors under test are in mutually parallel circuit branches all connected in a single capacitor discharge circuit and associated with means for simultaneously displaying signals indicative of current variations in each of the parallel circuit branches. This technique of simultaneous display not only minimizes the components in the circuit but more importantly provides a more sensitive and faster responding test apparatus.
