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.

RECONSTRUCTION OF 220 KV BUS IN THE SUBSTATION 400/220/110 KV PODLOG
KOMUNALNA ENERGETIKA / POWER ENGINERING, 21
This Article describes the reconstruction of 220 kV bus (isolation and the corresponding material) in the substation 400/220/110 kV Podlog. The switching substation 220 kV has been in operation since the early seventies. Due to the long year operation and to the worn out equipment, the operations are no longer reliable. Because of this, the bus reconstruction was made in 2011. At that time, there was a primary objective that during the reconstruction the electro energetic system would be as less disturbed as possible. For this purpose, has been analyzed the operation of the 400 and 220 kV network during the reconstruction. The focus was on the implementation of the reconstruction to ensure the least disturbed electro energetic system and consequently the uninterrupted supply of electricity to consumers.
