SCHEMATIC REPRESENTATION

LOCATION MAP

STEP DOWN TRANFSFORMER:

1. It is one whose secondary voltage is less than its primary voltage.

2. It is designed to reduce the voltage.

HIGH TENSION CABLES:

A high tension cable is used for electric power transmission at high voltage.

HIGH VOLTAGE UNIT

LOW VOLTAGE ROOM: This is a room where the electricity is

INSIDE

EXTERIOR

WHAT IS A FEEDER PILLAR? It is an effective electrical enclosure to provide electrical services for low voltage electrical distribution applications.

DISTRIBUTION BOARD:‘It is a component of an electricity supply system which divides an electrical power feed into subsidiary circuits.’

ELECTRIC SWITCHBOARD:• It is a device that directs electricity from • one or more sources of supply to smaller regions of usage.
