Note 1. Standard deviation is a measure of the statistical distribution about the mean as derived from

the formula:

α=

Calculation expression of frequency is as follows:

1

fOSC = 0.817 RT D CT + 1.42 D 10–6 (Hz)

[RT] = Ω, [CT] = F

Note 2. Maximum duration of short–circuit condition is 1sec (non–repetitive).
