Investigation of inverse time limit overload relays (1915)
Deiss, William Charles · leaf 16
stained short-circuit value of the current.Figure (l) shows the time elapsing between these two conditionsfor certain generators. Here it is seen that for these generatorsthe current has increased to one-fifth of the initial value inless than a second. Other generators may show a greater… … greater the dissymmetry the more the initial current decreaseis affected. After this time, however, the wave is fairly sym-metrical and the rate of decrease is the same. The rate ofdecrease for a single-phase circuit is faster than for a three-phase circuit, although the sustained single-phase…
