Method for validation of absolute phase angle characterization in wideband current shunts

Evaluation of the Relative Phase Comparison Method at Its Limits Used for Absolute Phase Determination of an AC Cage Current Shunt Group

“…The third row in the table shows the resistance and nominal current values of the shunts used in this paper. The highest ratio of the nominal resistance and current values between the shunts from [12] is 2.5, the ratio from [15] is 5, while the ratio in this paper is 10, which is in fact the limit of the statement mentioned above.…”

“…In [12], a statement that the proposed method is most suitable for shunts, where their respective RC are small (compared with 1/ω) and of the same order. The ratios of the nominal re and current values of the three geometrically identical shunts used in this paper a than those of the groups observed in [12,15], and are at the limit of the given sta The main goal of this paper is to evaluate the relative phase comparison metho given limit.…”

“…Nominal resistance values of the shunts used in this paper, as well as the ones from papers [12,15], are shown in Table 1. The third row in the table shows the resistance and nominal current values of the shunts used in this paper.…”

“…This paper focuses on the determination of the phase characteristics of cage current shunts. Several methods can be used to determine the phase characteristics of current shunts [12][13][14][15]. Some of the recent research papers cite methods such as using vector network analyzers to obtain the phase characteristics of current shunts [16] as well as using the Josephson voltage standard [17].…”
