A measurement setup is developed for accurate phase calibration of phasor measurement units (PMUs) and PMU calibrators using a stepped sine wave signal.Abstract:
A measurement setup is developed for accurate phase calibration of phasor measurement units (PMUs) and PMU calibrators. The measurement method is based on generating a reference signal with known phase with respect to a 1 pulse-per-second time reference using a stepped sine wave signal.read more

Measurement of Absolute Phase Error of Digitizers
TL;DR: In this article, the authors proposed a method for the measurement of digitizer absolute phase errors based on the characterization of generator phase response and measurement of the time delay between the sampling clock and a phase reference signal, taking into account the phase deviation introduced by generation system and the clock delay.

A New Phase Difference Measurement System With Differential AC/Single-Ended DC Switching for One TVC
TL;DR: A new phase difference measurement system based on the three-voltmeter method is described by introducing differential ac/single-ended dc switching for a thermal voltage converter (TVC) in consideration of the simulation results and the loading effects derived from the TVC.
