Capacitance Unbalance (Pair to Pair)

The difference in capacitance between the four conductors of two pairs of twisted insulated conductors. The unit of measurement for pair-to-pair capacitance unbalance is usually expressed in picofarads per 1,000 feet. Any difference in the wire diameter, the insulation thickness, uneven twisting of one or both pairs among the four conductors may result in pair-to-pair capacitance unbalance. Similarly, the lay length and proximity of the two pairs will also affect the capacitance unbalance pair-to-pair.
