Abstrakt: Results of theoretical and experimental investigations into the statistical characteristics of the voltage instability of type MN-3 measures are presented. The capabilities of linear mathematical models of the voltage instability of solid-body measures are considered and evaluated. It is shown that MN-3 type measures maintain a relative measurement (comparison) error in the range 1·10–8–3·10–8 only for a measurement period Δ t ≤ 1 h and that with Δ t ≈ 1 day, the error increases to values in the range 5·10–8–8·10–8, while when Δ t ≈ 1–3 months it increases to 5·10–7.
