Single line diagrams of substations 66/11 kV and 11/0.4 kV EEP
1.2 DIAGRAMS AND SCHEMATICS. Electrical diagrams and schematics of the substations must be available and up- to-date. Diagrams and schematics must be studied to understand the operation of the systems and the location and connections of all circuits. Protective devices, alarms, and interlocking circuits all are intended to protect the system.

Indoor substations Substation cabling 1. Medium voltage substations There are three common ways that an 11kV supply may be provided to a site: by a ring main, by duplicate feeders, or by a radial feeder or a single spur from a radial feeder. The duplicate supply may be provided with either automatic or manual changeover facilities.

Electrical Substation. Definition: The electrical substation is the part of a power system in which the voltage is transformed from high to low or low to high for transmission, distribution, transformation and switching. The power transformer, circuit breaker, bus-bar, insulator, lightning arrester are the main components of an electrical.

Substations usually include a ground mat. A ground mat is a system of bare conductors, on or below the surface, connected to a ground to provide protection from high voltages. Purpose of Substations. One purpose of a substation is to contain the equipment for changing electric energy from one voltage to another.

Electrical Substation Definition, Layout, and Uses of Substations
Indoor Substations: In these substations, the apparatus is installed within the substation building. Such substations are usually for a voltage up to 11,000 V but can be erected for 33,000 V and 66,000 volts when the surrounding atmosphere is contaminated with impurities such as metal corroding gases and fumes, conductive dust etc.

Single line diagram Figure 1 shows the single-line diagram of a typical 66/11 kV substation. Let's explain the main parts of it and how it actually works. There are two 66 kV incoming lines marked 'incoming 1' and 'incoming 2' connected to the bus-bars. Such an arrangement of two incoming lines is called a double circuit.

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. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.
