Abstract :
This paper outlines techniques, developed over a number of years, for corona pulse height indication on meters and recorders. The use of (quasi-) peak-reading meters for indicating the level of the regularly occurring largest pulses in an insulation structure is discussed. The circuit combination of a loosely coupled RF transformer with a tuned Stoddart radio noise meter is shown to be a corona pulse charge meter of great versatility and high sensitivity. Examples of corona pulse recording as a function of applied power frequency voltage, time, and location are shown.
