Indoor distribution substation layout with: 1 transformer LV switchgear HV switchgear (RMU - Ring main unit) Indoor distribution substation layout with 1 transformer and LV/HV switchboards Layout design drawing 3 Indoor distribution substation layout (OPTION A) with: 3 transformers 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.

Key Diagram of Substation | Key Diagram of 11kv/400v Indoor Substation Key Diagram of Substation 66/11KV: Fig. 25.10 shows the key diagram of a typical 66/11 kV sub-station. The Key Diagram of Substation can be explained as under: 1. There are two 66 kV incoming lines marked 'incoming 1' and 'incoming 2' connected to the bus-bars. The indoor substations work at much lower ambient, say at 28 Degree C, when the outside temperature may be above 40 degree C. Similarly the UG cable of power distribution is far superior to overhead system. This video gives details of a typical 11kV / 440V Indoor Distribution Substation in Electrical Power system. I have explained what is the key diagram of 11kv/400v indoor substation or single line diagram of indoor substation.watch full video to understand this conce.

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. Remark: The cast-resin dry-type transformer does not need a fire protection oil sump. However, periodic cleaning of the transformer is needed. Fig. B47 - General arrangement of a LV metering substation. 1: HV Switchboard, 2: Transformer, 3: LV switchboard, 4: Electronic devices / Capacitors. Fig. B48 - Examples of general arrangements of LV. Distribution substation Distribution substation typically operates at 2.4 - 34.5 kV voltage levels, and deliver electric energy directly to industrial and residential consumers. Distribution feeders transport power from the distribution substations to the end consumers' premises. What is Indoor Substations? Definiion & its Meaning - Circuit Globe Indoor Substation A substation in which the apparatus is equipped inside the substation building is called indoor substation.

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. The key diagram and the layout diagram of an indoor substation is shown in figure. The transformer is the most important equipment in a substation. For an indoor substation, the transformer shall have cable boxes at the HT and LT ends.
25.12 Key Diagram of 11kV/400 V Indoor Sub-Station Introduction present-day electrical power system is a.c. i.e. electric power is generated, trans The mitted and distributed in the form of alternating current. The electric power is produced at the power stations which are located at favourable places, generally quite away from the consumers. 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: 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. 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.
