Abstract
Electrical noise interference in the transmitter crowbar monitoring instrumentation system creates false sensing of crowbar faults during a crowbar firing. One predominant source of noise interference is the conduction of currents in the instrumentation cable sheilds. Since these circulating ground noise currents produce noise that is similar to the crowbar fault sensing signals, such noise interference reduces the ability to determine true crowbar faults, Analysis and test data are presented to show that by properly applying baluns (Balancing Units) and other noise rejection methods, the induced ground noise is reduced and proper operation of the crowbar instrumentation system is obtained.
