Indoor substation is inside a building. 15 Essential Basic Requirement for a Substation. Distribution substation A distribution substation transfers power from the transmission system to the distribution system of an area. Electrical area classification (EAC) is the process of determining the existence and extent of hazardous locations in a facility containing any of those substances. The area required for a low profile substation with a main and transfer bus scheme is also greater than that of the single bus, due to the additional switches and bus. In this respect the process interface given by the switchgear has to be clearly defined, whether this interface is conventional or based on the serial process bus using A typical substation facility consists of a small building with a fenced-in yard that contains transformers, switches, voltage regulators, and metering equipment that are used to adjust voltages and monitor ... detection, classification and measurement of disturbances on electrical power systems. Traction substations are used to convert electrical power as supplied by the power utility (or rail operators own network) to a form suitable for providing power to a rail system (via third rail or overhead line). Classification of substations on The Basis of Nature of Duties; Step-Up or primary substations: This substation are usually associated with generating stations.The generated voltage is low(3.3,6.6,11 or 33 kv) is stepped up to primary transmission voltage. The high-voltage transmission system (or grid) transmits electric power from generation plants through 163,000 miles of high-voltage (230 kilovolts [kV] up to 765 kV) electrical conductors and more than 15,000 transmission substations. vii NOTATION The following is a list of the acronyms, initialisms, and abbreviations (including units of measure) used in this document.
