“…These sampling voltmeters have a high-resolution integrating ADC (IADC) that operates according to the dual slope principle. The sampling process is such that the sampling instant is not a discrete point in time, but the measured signal is integrated by IADC over the aperture time of AD converter [20][21][22][23][24][25][26][27].…”

Determination of the phase difference between two sinusoidal signals with noise components using samples of these signals is of interest in many measurement systems. The samples of signals are processed by one of many algorithms, such as 7PSF, UQDE and MSAL, to determine the phase difference. The phase difference result must be accompanied with estimation of the measurement uncertainty. The following issues are covered in this paper: the MSAL algorithm background, the ways of treating the bias influence on the phase difference result, comparison of results obtained by applying MSAL and the other mentioned algorithms to the same real signal samples, and evaluation of the uncertainty of the phase difference.

“…Also the Primary Metrology Institutes (PMI) have set up their primary power standards for the sinusoidal conditions, using consolidated procedures [12][13][14][15][16][17]. Many of them are based on digital solutions, with analog to digital converters (ADCs) and proper techniques for signal sampling and reconstruction.…”

“…Therefore, the power standards laboratory of KRISS began research and development work of a sampling-based reference power standard to fulfill the requirement. The analog-to-digital converters (ADCs) are more important when a sampling technique is being employed (more details can be found in [1] and [2]). The sampling technique, dual channel method successfully used Correspondence: wije@kriss.re.kr in [1] and [2] and single channel method was used in [3] and [4], was employed by a few NMIs recently.…”

“…The method used single channel obtained low level of uncertainty with the phase-lock loop (PLL) synchronization, but the dual channel sampling method achieved high level of uncertainty. The one reason is that the sampled signal is not phase locked to the source signal [1,2] or not used proper algorithm to compensate the amplitude and phase errors [5]. The precision measurement of alternating (ac) signals by digital sampling can be best accomplished with the use of a PLL and proper method was suggested in [5] with hardware modification in dual channel sampling method to synchronize the voltage and current signals.…”

Abstract. We present a digital sampling algorithm that uses two high resolution integrating voltmeters that are synchronized by a phase-lock loop clock to accurately measure the active and apparent power parameters for sinusoidal power measurements. The developed system provides high precision measurements of the root mean square, phase and the complex voltage ratio of the ac signal with sophisticated algorithm which process the data in frequency domain. The system was designed to be used at the Korea Research Institute of Standards and Science as reference power standard for electrical power calibrations. The detail uncertainty calculations have shown that the accuracy of the measurements were better than 4 μW/VA (for k = 1) and the level of uncertainty was valid for the power factor range 0 ∼ 1 for both lead and lag conditions. The system is fully automated and allows power measurements and calibration of high precision wattmeters and power calibrators at the main power frequencies of 50 and 60 Hz.
