Abstract
A method for automatically replenishing oil in a coolant system of an electric generator produces a first signal representative of the speed of the generator and a second signal representative of the pressure of oil in the coolant system of the generator. These signals are combined with a reference signal to produce a control signal representative of a low oil condition in the coolant system. When such low oil condition exists, additional oil is delivered to the coolant system in response to the control signal. In the preferred embodiment, this additional oil is supplied from a source of high pressure oil.
