1.0 INTRODUCTION
Electric power transmission is the bulk transfer of electrical energy, from generating power
plants to substations located near to population centers. This is followed by electricity
distribution, which is the final stage in the delivery of electricity to the users. A distribution
system’s network carries electricity from the transmission system and delivers it to consumers’
meter socket. A variety of methods, materials, and equipment are used among the various utility
companies, but the end result is similar. Typically, the network would include medium-voltage
(less than 50kV) power lines, electrical substations and pole mounted transformers, low-voltage
(less than 1 kV) distribution wiring and sometimes electricity meters.
Electrical Distribution is the generation of one or more different types of energy, transform them
into electrical energy and the transformations of this energy for distribution to the point of
consumption for the consumers.
The productions, transmissions of continuous and reliable bulk supply and cost per unit of power
delivered are very important for consumers either for domestic and industrial usage of nation.
These will affect the labor and cost of materials produced by the industries and standard of living
for the people. Electrical energy naturally can be acquired from either non-renewable or
renewable energy resources.
The different types of energy is generate, transform it into electrical energy. The transmission
process will occur to distribute this energy for consumption of consumers. Electrical energy can
be coming from either non-renewable or renewable energy sources. Power plants can produce
AC or DC. Generally AC is used in modern power system because it easy to converted into high
or low voltages by means of transformers.
2.0 OBJECTIVE
1. Identify the transmission and distribution of electricity from Generating Power Plant to
TNB’s substations in Sec. 7 and into various buildings in UiTM Shah Alam
2. Determine the incoming voltages received at a particular building in UiTM Shah Alam.

3.1 POWER PLANT
The power plant generates 2420 MW of electricity the only power station in Malaysia
with triple fuel firing capability (gas, oil, and coal). In thermal power stations, mechanical power
is produced by a heat engine that transforms thermal energy. Most thermal power stations
produce steam, and these are sometimes called steam power stations. The power plant is referred
to as a cogeneration power plant or CHP (combined heat-and-power) plant. In countries where
