CORONA AND RADIO-INTERFERENC PHENOMENON REDUCTION ON 220 KV BUSBAR IN PODLOG SUBSTATION
KOMUNALNA ENERGETIKA / POWER ENGINERING, 9
The restoration and the occurrence of corona and radiointerference on the primary high-voltage equipment busbar 220 kV in substation 400/220/110 kV Podlog is presented in this paper. On the busbars 220 kV substation in Podlog was due to wear fully replaced jointing and insulation equipment, including elements of design electric field. After performing assembly work, measurements were taken corona and radiointerference. The results are showed poor results, it was necessary to approach the restoration status. To perform to the repair, were made laboratory measurements of partial discharges and radiointerference. On the basis of tests and comparative measurements have been developed and tested prototypes corona rings. Based on the measurement results, it was concluded that the remediation carried out by corona rings, which have been designed and a prototype was confirmed by measuring the conformity of the appropriate form of the electric field to be replaced suspension and insulation equipment busbar 220 kV substation Podlog.
