Web5Shunt Admittance of Overhead and Underground Lines. The shunt admittance of a line consists of the conductance and the capacitive susceptance. The conductance is usually … WebSince the shunt admittance of the underground cable is more than twice as large as shunt admittance of the overhead transmission line, the charging current of the underground cable is more than twice as large. 9-10. The underground cable is now supplying 8 kV to an 800 kVA, 0.9 PF lagging single-phase load. (a) == =. The =+ (* ( )( )*
WebAdmittance of an AC circuit is the reciprocal of its impedance. Using the impedance value one can easily derive the Admittance values of the circuit. Admittance ‘Y’ can be measured as Y = 1/Z. where ‘Z’ is the impedance, Z = R+jX. So, admittance ‘Y’ can be written as, Y = 1/R+jX. Thus, the formula of Admittance when derived from ... WebShunt Admittance Y. The shunt admittance matrix Y for aerial transmission systems can be easily derived, due to the fact that the surrounding air may be assumed as loss less, and …
