The impulse characteristics of porcelain insulators
Journal of the Institution of Electrical Engineers - Part I: General, 1941This report deals with the flashover voltage of insulators and gaps subjected to impulse voltages of different wave-shapes, with the relation between crest voltage and time to flashover at voltages above the minimum required for flashover, with breakdown while the voltage is rising rapidly, with the simultaneous application of impulse and alternating ...

Overhead Electrolysis and Porcelain Strain Insulators
Transactions of the American Institute of Electrical Engineers, 1915There is a slight leakage of current from trolley wires to earth through insulated supports on all electrical overhead construction, which if not checked permits a flow of current which gives rise to electrical separation of water into oxygen and hydrogen.

Temperature Researches of Porcelain Insulator
Advanced Materials Research, 2013When porcelain insulator operates in a harsh environment for a long time, it will cause leakage current increase, and lead to heating phenomenon. As a result, the temperature of porcelain insulator can be changed, which probably due to crack, breakdown or other factors.

Switching-Surge Insulation Level of Porcelain Insulator Strings
IEEE Transactions on Power Apparatus and Systems, 1964A quantitative research report is made here, based on tests of EHV (extra-high-voltage) insulator strings. Impulse, switching-surge, and a-c tests on vertical, horizontal, and 45-degree V-strings were carried out, using both positive and negative unidirectional impulses and 250- to 3,250-?sec (microsecond) switching surges.

Porcelain insulators in electrostatic precipitator
Journal of Electrostatics, 2015Abstract Electrostatic precipitators (ESPs) are commonly the most used filtration technology at industrial environments considering that ESPs allow to have a high dedusting efficiency. ESP insulators are key components in a precipitator inasmuch as if they do not work properly, the efficiency decreases quickly, and even having an inadequate ...
