31 First, based on a pollution flashover probability model for insulators under certain operation voltage and conditional probability, the fault probability of transmission lines was obtained.

32 The dissipating current and current suppressionafter flashover of semiconductor lightning eliminator are discussed in this paper.

33 The results indicate that flashover in building fires is a phenomenon of swallowtail catastrophe.

34 The correction method of switching impulse flashover voltage under high altitude was discussed and the altitude correction coefficient was given.

35 The room temperature vulcanizing(RTV) silicone rubber coating on the surface of insulator may increase the flashover voltage of contaminated insulator.

36 In comparison with simulation tests, the mechanism of guano - caused flashover is basically clarified.

37 For the insulator investigated the 50 % flashover voltage is reduced by 23.4 %.

38 The current and voltage response of surge discharge circuit to impulse flashover voltage test system is analyzed.

39 Silicone material has been widely used in power system to prevent pollution flashover of outdoor insulation.

40 The ice flashover accident of transmission line insulator is harmful for transmission line safe operation.

41 The room temperature vulcanized (RTV) silicone rubber coating on the surface of insulator can incrcase the flashover voltage of insulators due to the migration of hydrophobicity of RTV coating.

42 Although the AC flashover performance of a polluted insulator has been studied well, there is few study on the valid coefficient of creepage distance of different types of insulators.sentencedict.com

43 This paper expounds the mechanism of insulators contamination flashover and the principle of leakage current monitor.

44 By physical observation , flashover in building fires is a suggestive of a catastrophe process.

45 The insulation characteristic of insulator in vacuum is researched in the process of the high voltage breakdown along the insulator surface in vacuum, which is called vacuum surface flashover.

46 Icing weight and icing water conductivity are the two independent parameters which affect on the lowest AC flashover voltage of icing composite insulators.

47 The partial discharge and surface charge on organic glass are easier been observed than those on polyethylene, and the organic glass insulator flashover voltage is lower.

48 The critical flashover current reduces with the decrease of air pressure.

49 The effect of charges remaining on a dielectric plate upon the 50% impulse surface flashover voltage U_(50) in the non-uniform field(rod-plane gap)is investigated.

50 Before flashover occurs, a person in a burning room may crawl to safety along the floor.

51 The scheme that the auxiliary contact of the switch is taken as the auxiliary criterion composed of the flashover protection is not correct.

52 It was proved that this device can predict the occurrence of flashover successfully.

53 This is helpful for increasing the resistance to surface flashover and the high-voltage breakdown strength of solid insulators in high-vacuum.

54 To intensify basic external insulation level of power system-fundamental way for prevention of large-scale pollution flashover.

55 This method a simple understanding of the radiation processes in compartment fires such flashover.

56 Salt-water fog also cause an increase of impulse flashover voltage but a slight decrease of AC flashover voltage.

57 The basic measure to protect from large area pollutant flashover is to increase overall external insulation level for transmission and substation equipment.
