A new calculable cross-capacitor and associated impedance measurement chain is being built at the National Measurement Institute Australia (NMIA). The new system is intended to reduce the uncertainty of the farad as realised by a calculable capacitor

In a cross-capacitor with guard electrodes, the equivalent electrical length is sensitive to any variation in the cross section of the main electrodes unless measures are taken to compensate for this. The problem arises particularly in the case of a

Two new calculable cross capacitors are being constructed by the National Measurement Institute of Australia and the Bureau International des Poids et Mesures, with the aim of limiting sources of uncertainty to 1 nF/F, where achievable. In particular

An experimental determination of the effect of rotational skew in the alignment of the electrodes of a symmetrical cross capacitor shows that the capacitance as determined by the axial length is reduced by the skew. A theoretical model is introduced
