Here in this video, you will find an introduction to electrical power transmission equipment. One can get a glimpse of the Transmission network and its functions after watching this video. Alternating-current transmission operates at a specified frequency; direct-current transmission does not alternate at the AC system frequency. Various generating stations are connected to the load centers via a complex network known as Grid.In India, we have various control centers such as NLDC, RLDC, and SLDC for control and supervision of load flow.
What is in an electrical substation?
Electric power is delivered to consumers through a complex network known as Grid. Electricity is generated at power plants far away from the load center and moves through a complex system of electricity substations, transformers, and power lines that connect electricity producers and consumers at various voltages level.
What are the types of substations?
Air Insulated Sub-Station
Grid substations are integral units of the transmission and distribution of electrical energy. There are different ratings of grid substations and the layout of the grid substation varies with the specific rating.
The major part of any grid substations is (a) the Control room, (b) the switch yard, and (c) the store.
Proper lighting and illumination condition are required for the entire grid substation and its surrounding area.
various equipment installed in the electric substation.
- Busbar
- Power Transformer
- Lightening Arrester
- Current Transformer
- Potential Transformer
- Circuit Breaker
- Insulators
- Isolator
- Clamps and Connectors
TOOLS & PLANTS FOR GRID SUB-STATION
Like any other repair or improvement project around the GRID, electrical work requires tools. For most electrical projects, you’ll use mostly basic hand tools you already own, such as a hammer, tape measure, digital multimeter, level, and screwdrivers. There are also some specialty electrical tools that come in handy from time to time, and these are readily available at most GRID central stores
