“…They are generally characterized by high stability impedance with the variation of the current, temperature and time. Two technologies are prevalently used and commercialized: the so-called cage designs [10], [11] , where a number of resistive elements are connected in parallel, in a cage-like design and coaxial foil structures employing resistive metal alloys arranged in coaxial structures [12], [13], oriented at minimising their inductance.…”

This paper reports recent progress in developing a new asynchronous digital phase comparator for the precision measurement of phase difference of voltage ratio devices and calibration of functional elements of PMUs calibrator. The phase error of the proposed digital comparator is below 300 nrad at 50 Hz and 100 µrad at 100 kHz with applied voltages ranging between 500 mV and 3 V, whereas the phase error of cables and connectors was estimated to be 4 µrad at 1 MHz. Besides resistive dividers, the phase comparator has been employed for the characterization of frequency behavior of phase difference between the output and input of voltage and transconductance amplifiers for a PMUs calibrator. The system can also be an important tool for phase-frequency characterization of devices employed for specific wideband power measurements.

“…With the digital transformation and development of power grids, AC/DC current sensors are widely used in power equipment condition monitoring [1][2][3][4][5]. Low current sensors in power grids are mainly used for monitoring leakage currents and ground currents in cables and substation equipment, and the amplitude of low currents generally ranges from several hundred micro amps to over a hundred milliamps [6][7][8][9]. Due to the complex operating environment of power equipment on site, factors such as temperature, humidity, and electromagnetic interference directly affect the measurement accuracy of non-contact AC/DC current sensors.…”

In this paper, two type of 300mA AC/DC magnetic sensitive sensors were selected for an accelerated aging test under temperature stress. First, a temperature step test was carried out on the magnetic sensitive sensors in the range of (20~100) ℃, and then an accelerated aging test was conducted at 100℃. The difference between the changes in the AC scale factor and the DC scale factor of the two types of sensors was not significant, but the linearity of the DC scale factor of both sensors was significantly better than that of the AC scale factor at different current points. After 112 hours of acceleration at 100℃, the sensors of both samples exceeded the ±1.6% error limit, and the experimental results are of great reference value for estimating the service life of commonly used magnetic sensitive sensors in complex field environments.
