In primary substation, step down transformers are used to reduce the voltage to a range of 33KV to 66KV.Then electrical power is carried by the transmission system to a number of power or distribution substations where the electrical power is stepped down by means of a distribution transformer to voltage levels between 400V and 11KV for distribution to individual customers. CESU receives its electrical power at a transmission voltage of volts at 132KV-33KV at nineteen distribution substations located throughout its Five Circles in Orissa. CESU then distributes the power from the distribution substations across its distribution grid to its members at a three phase primary voltage level of 440V/11KV/33KV and a single phase primary voltage level of 230 volts.

CESU distribution grid consists of 1800 miles of single phase, 230 volt line and 750 miles of three phase, 440 line. In order to provide members electrical power at their required service voltages, distribution transformers are installed along the line at each business, residence and farm. Residential services and most farms require 230 volt single phase service which is provided by a single distribution transformer located on the pole or on a concrete pad at the member location. Some farms, larger businesses and the many irrigation services served by the cooperative require three phase services. These three phase services may be 440V,11KV,33KV. These services are provided by three single phase distribution transformers wired together to form a three phase bank located on the pole adjacent to the service, or by a single three phase transformer located on a concrete pad at the member location.

From the distribution transformer or transformer bank, secondary and/or service conductors are installed to the electrical meter, located either on a metering pole or on the member's house or building. The meter measures all energy used by the member in kilowatt hours (KWH). In the case of three phase services the meter also measures kilowatt (KW/KVA) demand which reflects the highest fifteen minute requirement for power. This meter is used by the cooperative to determine the member's electrical requirements as well as for billing purposes. From the meter the member or his electrician installs the service entrance conductors which provide power to the main electrical panel within the house or building from which the member's lighting and power loads are served.
