Abstract High-voltage transmission lines are long and may cross areas without mobile networks. The tower is equipped with monitoring equipment. information of the located in non-mobile network area difficult to return. What topology used for an important engineering problem. When number towers passing through a large, traditional design method based on engineer experience cannot be applied. Aim...

This paper proposes a simple transmission line model adopted with the partial element equivalent circuit (PEEC) method for lightning surge analysis. The proposed approach is employed for calculating tower surge responses and voltages across insulators of an actual transmission tower. The proposed approach increases the efficiency of the method in terms of computation time because of reducing a ...

In order to achieve reliable and high-speed 10kV power line carrier communications, it is necessary to study the characteristics of channel. Based on the multi-conductor transmission line theory, the chain matrix channel model is established. A lumped parameter model of distribution transformer is proposed from impedance measurement in the frequency range 50-500kHz. The terminal voltages and cu...
