What is the purpose of a power substation?
The purpose of a substation is to ‘step down’ high voltage electricity from the transmission system to lower voltage electricity so it can be easily supplied to homes and businesses in the area through lower voltage distribution lines.
What is meant by electrical substation?
Definition: Sub station. Description: An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers.
Does a substation generate electricity?
Substations themselves do not usually have generators, although a power plant may have a substation nearby. Other devices such as capacitors, voltage regulators, and reactors may also be located at a substation.
Can you build next to a substation?
If you are building near an overhead line, you must preserve the voltage safety clearance distances, both for the finished development and during construction (e.g. for scaffolding or cranes). If the development is near a substation you must be very careful about buried cables.
What is the meaning of 33 11kV substation?
Thus, when a substation is of rating 66/11 kV, means substation has been designed to receive 80 MVA on 66 kV and it will distribute the received power on 11 kV. Again, substation of rating 33/11kV means, the substation has been designed to receive 5 MVA of power at 33 kV and it will distribute the same on 11 kV.
What is the need of 33 11kV substation?
The 11kV lines are used in residential areas and is what feeds the local transformers, which then distributes power to the buildings in the area. 33kV lines on the other hand involve much higher voltages and are used to distribute power from one small sub-station to another.
What happens to electricity at a substation?
Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages.
What is an electric 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.
How does an electrical substation work?
Electrical substations are used to alter the flow of electrical energy transmission so just enough electricity is transmitted to homes and businesses. Substation electricians maintain and monitor the equipment at electrical substations, ensuring they continue to work properly and the proper flow of power is unimpeded.
What is in a substation?
Sub-station is a component of a Power System which includes various Equipments and is responsible for stepping up voltage levels for transmission or stepping down voltage levels for distribution purpose. A transformer is the heart of a sub-station which is responsible for changing the voltage levels without changing the frequency.
How do substations work?
How a Substation Works. Substations have many functions for controlling power flows. For example, they play a key role in dividing long lines into smaller sections. This helps to minimize any disruption to the continuity of service when a section is not functional, during a fault or maintenance period.
