A Fast Response Instrument for Measurement of Power System Phase Angles
Abstract:
A phase-angle measuring device is described which has a response time of one cycle of the signals whose phase angles are being measured. It has an adjustable full scale range which allows high-accuracy readings of small phase angle changes. An output is provided for continuous, fast response recording of phase angle changes suitable for use on an oscillograph. Some test results using the device are shown.read more
