Live working on vintage 138 kV steel lattice structures.

Live working on very old structures often poses unique challenges, such as dealing with the effects of arc rings and the behavior of old insulators. This paper presents the results of tests conducted for Public Service Electric and Gas to confirm that very old broken insulators can be replaced live...
