This paper describes the estimation of the stochastic flicker characteristics for an electric arc furnace (EAF) over a complete heat. These characteristics include stationarity, normality and correlation. Besides, the basic statistical probability were assessed by varying sampling period, too. The estimation and the assessment were implemented by a microcomputer-based instrumentation system. The test results for a typical AC arc furnace show that: (1) most flicker characteristics are stationary or weakly stationary during different periods of a heat cycle, but most of their probability density functions are not normally distributed; (2) the voltage and current fluctuations in the same phase are highly correlated; (3) the flicker converges at a value with a ±5% deviations from the value based on a basic sampling period, if the sampling period is decreased below 12 s.
