Gn. Aleksandrov et Ya. Gerasimov, ELECTRICAL STRENGTH OF A 3-PHASE INSULATION SYSTEM ON THE TOWER OF A COMPACT OVERHEAD TRANSMISSION-LINE, ELECTRICAL TECHNOLOGY, (3), 1996, pp. 31-40
Investigations of the electrical strength of three-phase insulation sy
stems with varying bundle constructions have been carried out. The num
ber of subconductors in a bundle varied from 4 to 8. The interphase di
stance varied from 2.8 to 6.2 m. Experimental tests have been carried
out using switching impulses with varying relationships of positive an
d negative polarity. It has been established that increasing the radiu
s of a bundle and the number of subconductors in a bundle leads to a d
ecrease in phase-to-phase breakdown voltage. Copyright (C) 1996 Elsevi
