Abstract

Measuring channels with ionization detectors as primary input are supervised by monitoring any imbalance between AC and DC components of the measuring currents, primarily to detect insulation failure of the connecting cable on account of heavy radiation and thermal losses. Detection of the imbalance is independent from radiation changes to be measured.
