In the work of live actual job, during using condensing type electroscope electrical verification, when electrification in high voltage conducting wire or charging equipment go out
When existing turning, strange become will occur for the field strength and electric potential gradient of periphery high voltage electric field.When electroscope enter the region,
When potential difference is less than the initiation value of setting between axial upper and lower two electrode, then there is " electrical verification blind area ", " there be electricity ", erroneous judgement is
" no electricity ".Electrical verification blind area is exactly that high-tension apparatus charges really, but cannot detect showing for equipment live with qualified electroscope
As.Electrical verification blind area is generally present in substation's electrification in high voltage bulk area major part or conducting wire connecting corner part and high pressure
The angle of equipment and connecting line, and during electrical verification, because the problem of angle so that operating process difficulty increases, and
And electroscopic device cannot be adjusted according to the height of distinct device, it is less efficient；And since electroscope is light indicating type,
Equipment is distant, in the case of daylight interference, and the personnel operated on the ground cannot see the indicator light of electroscope clearly, to electrical verification
As a result it has an impact.
