The objective of this Study of Substation Equipment and Protection Electrical and Electronics Engineering EEE Final Year Project Report is to present protection guidelines that address the above concerns and prevent the electronic equipment failures in substations.

Test methodologies and data supporting these guidelines are also presented. The specific areas of focus include grounding and shielding practices for substation control and communication cables. During their live time protection relays operate seldom or never.

But, one protection relay that does not operate or operates to late when there is a fault in the network or component will have disastrous consequences for the energy supply and human safety. On the other hand if a protection relay operates when it is not intended to operate it may have large economic consequences.

The economics of generation of electrical energy and the huge demands of power in the modern times require creation bigger power plant. These may be hydro, thermal, atomic etc. The transmission network is inevitable.

Large and high voltage transmission lines are necessary to transmit huge blocks of power from the source of generation to load centers. In b/w the power plant and ultimate consumer a number of transmission and switching stations have to be created. This is done by SUBSTATION.

A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Electric power may flow through several substations between generating plant and consumer, and its voltage may change in several steps.

A substation that has a step-up transformer increases the voltage while decreasing the current, while a step-down transformer decreases the voltage while increasing the current for domestic and commercial distribution.

The word substation comes from the days before the distribution system became a grid. The first substations were connected to only one power station, where the generators were housed, and were subsidiaries of that power station.
