Skin Effect and Proximity Effect: The distribution of current throughout the cross-section of a conductor is uniform only when DC is passing through it. On the contrary when AC is flowing through a conductor, the current is non-uniformly distributed over the cross-section in a manner that the current density is higher at the surface of the. In addition to standards and bridges for resistance and capacitance calibrations, facilities for calibrating standards of self- and mutual inductance have been developed. At present, the main attention is paid to increasing the frequency range, in which the calibrations are made.

The internal standards are manufactured from premium quality resistance wire with low temperature and load coefficient. For the selection of the standards, a special switch of our own construction is used ensuring a long and trouble free operating life.
Electrical Impedance: Principles, Measurement, and Applications provides a modern and much-needed overview of electrical impedance measurement science and its application in metrology, sensor Author: Luca Callegaro. This allowed four-terminal measurements and had most of the advantages of a bridge but a more complicated calculation was required.
