The document describes the components and flow of electricity from high voltage transmission cables to residential and commercial buildings. Electricity travels through step down transformers to reduce the voltage and is then distributed to buildings through feeder pillars, distribution boards, and switchboards, where meters monitor usage before powering individual circuits at safe low voltages. Diagrams show the schematic representation and location of these components in the electric grid system.

7. STEP DOWN TRANFSFORMER:
1. It is one whose secondary
voltage is less than its
primary voltage.
2. It is designed to reduce the
voltage.

8. HIGH TENSION CABLES:
 A high tension cable is used
for electric power transmission at
high voltage.

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

12. 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.
