IMPACT OF NON-ELASTIC EXTENSION OF CONDUCTORS ON THE OVERHEAD POWER LINE CONDUCTOR SAGS
KOMUNALNA ENERGETIKA / POWER ENGINERING, 14
Proposed paper deals with the problems regarding a non-elastic elongation of overhead conductors known as creep phenomena on account of mechanical yielding of material. Impact of non-elastic elongations of conductors is directly connected with the conductor sags and with smaller clearances between conductors and ground. Some results related to the researches in permanent elongations of conductors of the ACSR 490/65 type are presented, where compesation methods are applied as well.

CALCULATION OF THE TEMPERATURE OF THE OVERHEAD POWER LINE CONDUCTOR
KOMUNALNA ENERGETIKA / POWER ENGINERING, 16
Temperature of the overhead power line conductor during operation represents one of the basic limit parameter for overhead power line operating. The allowed conductor heating must be under the limit values, because of high impact to the mechanical parameters of the conductors and conductor sagging. In the paper, all of the results are obtained with the CIGRE method, while obtained results are shown in program package Matlab.
