7. Conclusions
- Inception voltage and flashover voltage decreases with increase in ESDD and NSDD.
- Increase in humidity and temperature leads to decrease in inception voltage and flashover voltage.
- Dry bands along the insulator surface leads to increase in arc inception voltage and flashover voltage.
- The width and number of dry bands along the insulator surface also changes the inception and flashover voltage.
- Flashover voltage and arc inception voltage were high in the case of middle dry band as compared to high voltage and ground end dry bands.
- Dry band configuration influences the flashover characteristics.
- Insulator orientation plays important role in the flashover behavior under polluted conditions.
