Abstract
A current/flow comparator for generating an alarm signal whenever the instantaneous flow rate of a coolant fluid cooling the armature of a dynamoelectric machine falls below a predetermined percentage of a desired instantaneous flow rate, which desired flow rate varies as a function of the square of the instantaneous current flowing through the armature, is disclosed.
Claims9
A current/flow comparator for generating an alarm signal whenever the instantaneous flow rate of a coolant liquid cooling the armature of a dynamoelectric machine falls below a predetermined percentage of a desired instantaneous flow rate, which desired instantaneous flow rate varies as the square of the actual instantaneous current flowing through said armature, said comparator comprising:
- means for generating a first signal representative of the actual instantaneous value of said flow rate;
- means for generating a second signal representative of the actual instantaneous value of said armature current;
- and
- means responsive to said first and second signals for generating an alarm signal whenever said instantaneous flow rate falls below said desired instantaneous flow rate by more than said predetermined percentage.
