ON THE NEED TO INCREASE THE RELIABILITY OF LINEAR INSULATORS FOR DISTRIBUTION NETWORKS 10-20 KV
Electrical engineering & Electromechanics, 2018 Introduction. In Ukraine high voltage overhead distribution lines (OL) of class 6 and 10 kV are the most extended. Their total length exceeds 280,000 km. More than 95% of the lines are made on line supports from reinforced concrete racks. On all poles of

High voltage insulation properties of HFO1234ze [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2015 Recently it was shown that it is possible to predict the breakdown voltages of arbitrary electrode configurations under standard voltage applications for electron attaching gases with a stepped leader model originally proposed for SF₆. In this contribution this model was applied to the hydrofluoroolefin HFO1234ze.
