Four Terminal-pair Coaxial Standards of Capacitance
نویسندگان
چکیده
Four terminal-pair coaxial capacitance standards with nominal values of 1 pF and 10 pF have been realized and, using a uniform transmission line model, their frequency dependences have been evaluated. 1:1 comparisons against reference capacitors with known frequency dependence (Agilent 16381A and Agilent 16382A) have shown that the values of the 1 pF and the 10 pF standard change by 0,04 % and -0,05 % respectively when frequency increases from 1 kHz to 1 MHz.

Traceability Chain of the Capacitance Unit to Quantum Hall Effect at Inmetro - Four-terminal Coaxial Bridge
− This paper describes the development of a four-terminal coaxial bridge, part of the traceability chain of the capacitance unit to the quantum Hall effect, in construction at Inmetro. This bridge will also be used to calibrate AC resistance and high-value capacitance standards. Here we describe the final construction stages and preliminary measurements of the four-terminal coaxial bridge. We a...
متن کاملAn Easy-To-Use Combination Four-Terminal-Pair/Two-Terminal-Pair AC Transformer Bridge
A new four-terminal-pair bridge, capable of achieving a relative standard uncertainty of 1×10-9, was constructed at the National Institute of Standards and Technology by converting a two-terminal-pair bridge. The conversion requires only the addition of components which are easily removed if two-terminal-pair measurements are to be made. The design and testing of this bridge is described. The n...
متن کاملResonance frequency of four- terminal-pair air-dielectric capacitance standards and closing the metrological impedance triangle
A new technique for determining the resonance frequency (f0) of four-terminal-pair air-dielectric capacitance standards is discussed. The resonance frequency is determined by measuring four parameters of the capacitance standards over a range of frequencies near f0. These parameters are the two-terminal-pair impedance coefficients as defined in an impedance matrix. From a knowledge of the four-...
متن کاملUnequalized Currents in Two Terminal-pair Coaxial Capacitance Bridges
It is necessary to maintain conditions of zero net currents in the cables of ac coaxial bridges. Current equalizers are used for dealing with this problem. It is shown here how they were applied in the construction of a two terminal-pair capacitance bridge with an uncertainty of about one part in 10.

The Electricity Division at the Nationals Institute of Standards and Technology (NIST, formerly NBS) has developed the capability to characterize capacitance and dissipation factor for four terminal-pair (4TP) air dielectric capacitors at frequencies from 1 kHz to 10 MHz. The method, based on work by Cutkosy and Jones of NBS and recent developments by Hewlett-Packard Japan, involves single-port...
