In hydro-electric power station equipped with pressure regulator, if the action of the pressure regulator be ideally perfect, there would be no pressure-rise at all in the penstock. But in actual case, there occurs some amount of pressure rise, even if the pressure regulator is equipped. We may mention, for the causes of this pressure-rise : -(a) The (effective) passage-area of the regulator does not necessarily coincide with the passage area of guide vanes of water turbine. (b) There is a time lag in action of pressure regulator from the time of beginning of guidevane closure. Taking these two factors (a) and (b) into account, the Author has made a theoretical calculation of the pressure rise of this nature, and discussed the effect of these two factors (a) and (b) upon the form of the pressure-time curve. Some comparison with measured curves of actual hydro-electric power plants are also given.
