Tests for Information on Shaft Revolution Indicators, Magneto-Voltmeter Type, Westinghouse Electric Co.- MFR

Abstract

A magneto-voltmeter type shaft revolution system was submitted to the Laboratory for an investigation of its performance and to permit obtaining information for specification development. The system included an induction-type generator and two indicators. Its functions and general design were investigated under simulated Service conditions and checked against applicable performance limitations and Service requirements of specification, reference (b). Performance of the system was investigated over the temperature range 40 degrees F. to 130 degrees F. The initial accuracy of the system under ordinary temperature conditions was not within the broadest limits allowed by the specification (for type B systems) even if t he span of the errors were equally divided by adjusting the zero reference. Both the temporary and permanent effects on the system of the simulated Service conditions (except extreme temperatures) were relatively small.
