Power System is an integrated network that interconnects the installations for generation, transmission and distribution of electricity. In Bangladesh electricity is generated at 50 Hertz frequency and at a nominal voltage of 11 KV (Kilo Volts) or 15 KV to be stepped up through transformers to 132 kV or 230 kV for feeding to the grid i.e. a high voltage transmission network that transmits the power to grid substation transformers to be stepped down at 33 kV. 11 kV and 0.4 kV for delivery to the consumers of various categories.

Power companies related to
distribution are responsible for
stepping down electricity from the
high voltage of 132 kV at the
transmission level, to the lower
voltage levels of
33kV/11kV/0.415kV depending on
categories of customers. Electricity
in most residential homes is
supplied at voltage level of 0.415kV.
These companies are also
responsible for marketing and
selling of electricity to customers.
All the revenue which is needed to
sustain in the electricity industry is
earned through the distribution
sector. By delivering electricity to
the customers, the distribution
companies maintain their
community's network of
distribution wires. They also step
down the voltage of electricity to
make it safe for the use of
customers and provide electricity to
end-users at market rates.
