Arcing Horns
Arcing Horn is basically projected conductors used to protect the Insulators in High Voltage Transmission Line from damage during
flashover. Over voltage on Transmission Line may occur due to various reasons like lightning strike, sudden load variation, fault etc.
Due to this high voltage a flash over may take place which will shatter the Insulator. To prevent Insulator from such an occurrence, it
is very important that flashover do not take place through the Insulator. Arcing Horn serves this purpose by providing a bypass
flashover the high voltage across the insulator using air as a conductive medium.
Application:
Arcing horns are used to protect the transmission conductors, insulators, transformers bushings and other transmission equipments
from lightning high voltages, transient voltages and surge voltages. Arc horns are working under the principle of arcing.
