AI Customer ServiceThe system of Capacitance of 3 Core Cables shown in Fig.11.18 (iii) reduces to the equivalent circuit shown in Fig. 11.20 (i). Therefore, the whole cable is equivalent to three star-connected capacitors each of Capacitance of 3 Core Cables [See Fig. 11.20 (ii)], If V ph is the phase voltage, then charging current I C is given by ;
It may be noted here that if value of C N (= C e + 3C c) is desired, it can be found directly by another test. In this test, the capacitance between two cores or lines is measured with the third core free or connected to the sheath. This eliminates one of the capacitors C e so that if C 3 is the measured Capacitance of 3 Core Cables, then,
The Capacitance of 3 Core Cables is much more important than that of overhead line because in cables (i) conductors are nearer to each other and to the earthed sheath (ii) they are separated by a dielectric of permittivity much greater than that of air. Fig. 11.18 shows a system of capacitances in a 3-core belted cable used for 3-phase system.
The three delta connected capacitances C c [See Fig. 11.19 (0] can be converted into equivalent star connected Capacitance of 3 Core Cables as shown in Fig. 11.19 (ii). It can be easily shown that equivalent star capacitance C eq is equal to three times the delta-capacitance C c i.e. C eq =3C c.
A 3 cored cable is preferred up to 66 kV. Beyond that, insulation required for the cable is too much. For higher voltages, 3 cored constructions become too bulky, and hence, even with some limitations we employ single cored cables. High tension cables: These have a maximum voltage handling capacity of 11 kV.
They lay of a belted cable makes it reasonable to assume equality of each C c and each C e. The three delta connected capacitances C c [See Fig. 11.19 (0] can be converted into equivalent star connected Capacitance of 3 Core Cables as shown in Fig. 11.19 (ii).
