The leakage current is dependent on the applied voltage, the insulation resistance of the cable insulation, and any other series resistance in the circuit. This value becomes very difficult to read accurately at high voltages because of the possibility of end leakage currents as well as the transient currents. 4) = Leakage current in microamperes per 1000 feet Voltage between conductor and ground in volts Rz = Insulation resistance in megohms for 1000 feet E = The total current is: 47 Copyright © 1999 by Marcel Dekker, Inc.

Mutual Inductance. (L,) is the common property of two associated electric circuits that determines, for a given rate of change of current in one of the circuits, the electromotive force induced in the other. 6 Capacitance This is the property of an electric system comprising insulated conductors and associated dielectric materials which determines, for a given time rate of change of potential difference between the conductors, the displacement currents in the system. 7 Reactance Reactance is the product of the sine of the angular phase difference between the current and potential difference times the ratio of the effective potential differ- Copyright © 1999 by Marcel Dekker, Inc.

More flexibility is achieved by increasing the number of wires in the conductor. Class C has one more layer than Class B; Class D one more layer than C. ). These are covered by ASTM specifications [3-2, 3-3,3-41. Classes C and D have approximately the same weight as Class B and an OD within 3 mils of Class B conductors. 1 109 91 ~ 0 . 0768 The following formula may be used to calculate the number of wires in a concentric stranded conductor: n where = 1 + 3 N (N+l) n = total number of wires in stranded conductor N = number of layers around the center wire Copyright © 1999 by Marcel Dekker, Inc.
