Experimental Study of the Spectral and Correlation Characteristics of Low-Frequency Fluctuations in Tungsten Filaments
Low-frequency current fluctuations in tungsten filaments are experimentally studied in a frequency interval of 6 × 10–5–1 Hz. The experiments are carried out at heating temperatures of the filaments of 2250 and 2...

Bridge Method for Studying the Spectra of Current Fluctuations in Tungsten Filaments in the Frequency Range 1.5·10–5–5·10–1 Hz
This article discusses the absence of methods for measuring low-frequency (LF) fluctuation processes at high temperatures and proposes an original bridge method for measuring the spectra of LF current fluctuat...

Metrological Aspects of Measuring the Volume-Average Temperature of Filaments in Illuminating Lamps
We study metrological problems encountered in measuring the volume-average temperature of heated tungsten filaments. The process of heating is realized by electric currents within the temperature range 300–300...
