“…The quick rise of lightning's front wave and timedependent decline of tail wave are most common characteristics. Therefore, after long-lasting observation and study, many researchers proposed a very similar lightning surge mathematical function, of which Double Exponential Model is commonly used [9]. …”

The contingency probability analysis on transmission tower under lightning stroke with various configurations of line arresters is proposed in this paper. The simulation and calculated approach is developed to evaluate the performance for different line arrester installed scheme and capacity. The Electro-Magnetic Transients Program (EMTP) is used to simulate the effect of system under lightning strike on transmission system. The considered components of the study system including lightning surge, line arrester, transmission line and tower. All of the components are modeled to fit the situation of Taiwan under EMTP for more realistic purpose. Then, the proposed simulation procedure is applied to calculate the failure probability of the line arrester by considering the random properties of lighting current, including the wave-tail and peak value of the lightning surge. The comparative studies, which considering the thermal capacity, number of installed arresters, installation position of the arresters, and the footing resistance of transmission tower, are conducted to provide appropriate suggestion for installation strategies of the line arrester. Results obtained from this study can provide the electric utility with valuable quantitative information due to the cost-benefit analysis for the installing of line arrester.

Different functions have been used to model the lightning return-stroke current with the aid of direct current measurements at tall structures. In this paper, a comparison between the Pulse function and Heilder function is carried out to find out the suitability of each of these functions for simulating the lightning return-stroke current, measured at the CN Tower. An automated system for determining the CN Tower lightning return-stroke current waveform parameters is introduced. The curve fitting technique of this system and the estimation of the initial values of the simulation function parameters are presented. An artificial lightning signal, free of noise and reflections, is used as a reference signal for evaluating the parameter extraction system. Finally, cumulative statistics of the CN Tower lightning return-stroke current waveform parameters (peak, maximum rate of rise, risetime, pulse width, decay time and charge) are derived using the Pulse function parameters.

“…As lightning in nature has great number of wavechanging patterns, some types of forms should be designed to apply to solve the power system problems. References [5]- [7] show lightning current waves are classified into two main types: double exponential model [5] and Heidler model [7]. The latter one is adopted by more researches, and this paper also uses this model as the lightning current source I g , represented as below.…”

This paper presents a systematical evaluation experience on the performance and economic studies of line arresters for a 69 kV transmission system in Taiwan. The transient over-voltage phenomenon in high voltage transmission lines under lightning by using the Electro-Magnetic Transients Program (EMTP) package is well modeled and analyzed. The modeling for the simulated system including lightning, transmission line, transmission tower and line arrester are all considered to have more practical results. The cost and benefit evaluation for line arresters installation is then conducted to provide a reasonable suggestion for lightning protection. The performance of line arresters is evaluated by considering different installation schemes and lightning currents. Finally, a Taiwan's experience is illustrated from both of the cost and benefit points of view.
