Simulation Analysis for 33 kV Porcelain Insulator String Based on Room Temperature Vulcanize Coating

2023 IEEE 3rd International Conference in Power Engineering Applications (ICPEA), 2023
Porcelain insulator is widely used in high voltage (HV) transmission lines due to its high mechanical strength, performing well on heat and aging resistance. However, porcelain insulator string is always exposed to environmental contamination.

The impulse characteristics of porcelain insulators

Journal of the Institution of Electrical Engineers - Part I: General, 1941
This 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 ...

Study on the Mechanism and Electrical Characterization of the Distribution Porcelain Insulator Incipient Fault in the Non-Effectively Grounded System

IEEE Transactions on Power Delivery
The porcelain insulator incipient fault (PIIF) is a self-clearing discharge process caused by water entering the crack of the porcelain insulator. It will not result in a tripping operation but may evolve into a permanent grounding fault after multiple ...

Overhead Electrolysis and Porcelain Strain Insulators

Transactions of the American Institute of Electrical Engineers, 1915
There 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.
