What's the function of Neutral section and section insulator in OHE

Question

Accepted Answer

The neutral section and section insulator in OHE have important functions in electrical systems.

The neutral section is used to provide a return path for the current in the electrical system.
It helps maintain the balance of electrical potential between the overhead wires and the ground.
The section insulator is used to electrically isolate different sections of the overhead wires.
It prevents the flow of current between adjacent sections, allowing for better control and maintenance of the system.
The section insulator also helps in reducing the risk of electrical faults and short circuits.

Accepted Answer

Give the purpose and location of neutral section and section insulator.

Accepted Answer

Purpose of Neutral section: Passing of pantograph under insulated overlap will cause short circuit between two phases, damaging OHE & pantograph. To avoid this bridging, a neutral section is inserted between them. Location: Located between two substations. Purpose of Section insulator: Section insulators are provided to insulate OHE of one elementary section from the OHE of another adjacent elementary section. Location: Located at cross over from one track to other, from main line to siding. Like 0 Dislike 0
