Pulse characteristics of linear gas-discharge indicators
Despite the observed deviations of the LGI operating characteristic from linearity with a pulsed supply, the pulsed supply mode can be used with pulses having long durations in the order of 1 to 10 msec where the departure from linearity is negligible, and with pulses having short durations in the order of 100 μsec which are more convenient from the viewpoint of the balancing circuit design. In this case it is recommended that the pulse duration should be stabilized to an error of about 1% and that a nonlinear scale be used.
A pratical investigation was carried out on the supply conditions of an LGI with current pulses of 1 msec duration. At a frequency of 50 Hz the average power consumption was reduced by a factor of ten. It proved possible to adjust the LGI brightness by varying the pulse supply frequency from 30 or 40 up to 250 Hz.
