Shunt admittance matrix

WebIts SI unit is Siemens. Admittance is the inverse of impedance. Admittance formula. As we know, admittance is the reverse of impedance. The formula of admittance can be expressed as: Y = 1 Z. Where, Z = R + jX. So, we can write the admittance equation as: Y = 1 (R + jX) Where, Y is admittance, Z refers to impedance, R is resistance (real part), Web• per unit length series impedance matrix, Z = R + jX and • per unit length shunt admittance matrix, Y = G + jS.
