This paper presents a new phase frame modelling using recursive convolution for the transient analysis of unbalanced transmission lines. The recursive convolution are formed from the first and second order transfer functions derived via an approximation method for the frequency dependent characteristics of the phase frame attenuation and surge admittance. The accuracy of the approximation is considerably high. Then the model is free from the contradiction to the physical causal relationship observed in the frequency dependent modal transformation matrix used by the modal frame model with full representation of frequency dependence of unbalanced transmission lines. The resemblance of wave forms between simulation and field test results are good.
