Abstract
The detection of corona discharge in low pressures (high altitudes) is important for proper design of insulation systems. Commercially available discharge detectors are designed to measure corona discharge at atmospheric pressure. This paper shows that these devices are insensitive when low pressure corona discharge is investigated. A test arrangement was designed to look at the frequency spectrum of corona discharge current in parallel copper wires at various pressures. Test results indicate that as the pressure decreases, the frequency components of the corona discharge current also decrease. At 0.7 Torr, a strong 17 kHz component becomes very pronounced and the spectrum is limited to 37.5 kHz or less. Current detection methods now in use are not suitable to measure corona discharge at high altitudes.
