Patent number: 4264856Abstract: In a generating system having a shunt-type regulator for exciting the field of a generator during normal operating conditions, circuitry is provided for supplying voltage to a field winding to maintain excitation of the generator during excessive output current conditions. This circuitry senses the low voltage indicative of a fault or overload condition and in response boosts the field of the field winding during such an excessive output current condition an amount sufficient to maintain generator excitation during that particular condition. It does this by impressing a voltage, supplemental to that supplied by the regulator, upon the field winding during the condition. As a result the excitation of the generator is maintained.Type: GrantFiled: March 23, 1979Date of Patent: April 28, 1981Assignee: Basler Electric CompanyInventors: Waldo J. Frierdich, Thomas F. Kappel
