Abstract
Some strands were melted and broken in a 140 mm2
OPGW (composite fiber-optic ground wire) in a 187 kV transmission
line. It was assumed that this was caused by a lightning strike.
DC arc tests simulating lightning strikes were carried out, and the
melting and breaking characteristics of OPGW strands were obtained.
The electric charge of the lightning strike that damaged the
OPGW was estimated from the number of strands broken by the
DCarc. In this paper, theDCarc test results, and the test conditions
required to simulate a powerful lightning strike are described.
