Abstract :
Based on the measurement of lightning current cooperating with the rocket-triggered lightning experiment in winter, executed from 1986 through 1995, the authors have analyzed the energy absorption characteristics of gapless metal-oxide surge arresters (MOSA), assuming that they are installed on every tower of a 3-phase transmission line, by EMTP. The analyzed results of energy absorption for each MOSA connected in parallel showed that the ordinary 10 kA class MOSA installed on every tower has a possibility to share the large winter lightning energy except in some exceptionally severe cases. This paper discusses the absorbed energy in line MOSA regarding the dispersion of tower footing resistance (TFR), and the interaction between line and substation MOSA with various value of residual voltage
