Development of a Partial-Discharge Detection System for Traveling-Wave-Tube Testing.

Abstract

The development of a test system to detect and monitor partial discharges (PD) in a traveling wave tube (TWT) is described. The assembled system is capable of monitoring discharges of a magnitude ranging from 0.25 pC to above 250 nC. During this operation, the TWT can be subjected to pressures ranging from atmospheric to below .01 Torr and to temperatures ranging from -20 to +90 C. Developmental studies, which included the analysis of various test circuits and the examination of test circuit calibration that resulted in the present test system are reported. Investigations in addition to the TWT tests that have been conducted with this system are discussed. For long-term testing of TWTs, a microprocessor-controlled PD test system is proposed. (Author)
