Abstract
An analysis of very fast front transient overvoltages,
generated as a result of induced effects of lightning, across a
photovoltaic plant is investigated. The EMTP-RV version 3.3
computer software platform is used to simulate surge voltage
magnification. Selection and placement of surge arresters for
effective protection of power transformers are conducted. Results
show that selected arresters placed on bus 4 and coordinated with
those placed on bus 5 and 3 ensure surge amplitude reduction
of 33% on bus 4.
