Maintenance of Electrical Equipment

Maintenance of Electrical Equipment IN the previous section it was explained how the terminal P.D. of a shunt dynamo can be adjusted manually by means of a field regulator. Although such a device may find a place where large dynamos are concerned, conditions involving a fluctuating load necessitate some form of automatic voltage control. Where a floating battery is used with the dynamo it is further desirable that the dynamo output should be suited to the state of charge of the battery, and again that it should change with every variation of load. While it would be quite possible to make all these adjustments by manual controls, such a scheme is obviously ruled out on motor vehicles and aeroplanes. The basic aim of the automatic voltage controller must, therefore, be to keep the battery fully charged, but the actual achievement of this aim turns out to involve much greater complexity than would be anticipated. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Aircraft Engineering and Aerospace Technology Emerald Publishing

Abstract

IN the previous section it was explained how the terminal P.D. of a shunt dynamo can be adjusted manually by means of a field regulator. Although such a device may find a place where large dynamos are concerned, conditions involving a fluctuating load necessitate some form of automatic voltage control. Where a floating battery is used with the dynamo it is further desirable that the dynamo output should be suited to the state of charge of the battery, and again that it should change with every variation of load. While it would be quite possible to make all these adjustments by manual controls, such a scheme is obviously ruled out on motor vehicles and aeroplanes. The basic aim of the automatic voltage controller must, therefore, be to keep the battery fully charged, but the actual achievement of this aim turns out to involve much greater complexity than would be anticipated.
