Calibration of Multi-decade Inductive Voltage Dividers
Abstract: A method for calibrating multi-decade inductive voltage dividers has been developed which makes it possible to determine both the inphase and the quadrature error for ratios of i /11, i = 1, 2, ..., 10 in the frequency range from 400 Hz to 5 kHz. Calibration is made by comparing the divider under test against a reference two-stage divider having a ratio winding with 11 identical secti...
متن کاملThe Design and Self-Calibration of Inductive Voltage Dividers for an Automated Impedance Scaling Bridge
The design and construction of inductive voltage dividers (IVDs) for use in impedance bridge applications in the 50 Hz to 1 MHz frequency range is described. Two dividers are described; one designed to operate from 50 Hz to 2 kHz and the other designed to operate from 2 kHz to 1 MHz. Preliminary comparison results of the new IVDs over the 100 Hz to 50 kHz frequency range are given. A new bridge...
متن کاملEVALUATION OF INDUCTIVE VOLTAGE DIVIDERS AND 10 nF CAPACITORS IN A CAPACITANCE CALIBRATION METHOD
Researchers within the Quantum Electrical Metrology Division at the National Institute of Standards and Technology (NIST) have implemented a calibration procedure for four-terminal-pair capacitance standards from 0.01 μF to 100 μF [1], [2]. This method depends on the accurate characterization of a 1 nF capacitor and an Inductive Voltage Divider (IVD) 1:10 ratio from 100 Hz to 100 kHz. This pape...
متن کاملA Lecture on Accurate Inductive Voltage Dividers
The United States Naval Academy is an undergraduate school with a successful engineering program. An underlying philosophy in the Systems Engineering Department is to emphasize hands-on experience while maintaining a solid theoretical background. To realize this principle, both teachers and students face many challenges. In this paper an attempt is made to teach students how to build a very acc...
متن کاملElectronic compensation of inductive voltage dividers and standard voltage transformers
A new compensating system is proposed to reduce the ratio error and the phase error of inductive voltage dividers and standard voltage transformers, operating at no load. An electronic amplifier reduces the input current, which is the main cause of error in low-frequency applications, while at the same time the input impedance is greatly increased.
