If you have many Gas turbine Generators working on parallel, if any fault happened in one generator ( so this generator is no longer feeding the load ) load shedding panels will disconnect a group of predetermined Less important loads to help the working generators in the additional load (which may come after fault of the mentioned generator ).

What is tertiary bus in substation?
Many substation transformers have three windings - the primary, secondary, and tertiary. The tertiary bus is the bus connected to the tertiary of the transformer. this is often used as station power for the substation, since the tertiary is very often a distribution level voltage (2 - 15kV).
What is grid substation?
this type of substation are considered important because any sort of disturbance in these substation may lead to the failure of grid.this type of substation are used to transmit huge amount of power from one point to other point in the gridAnswerA substation is a location where electricity transmission/distribution voltage-levels are changed and switching is carried out, as opposed to a power station, where electricity is generated. A substation, therefore, is a yard/building in which there are transformers, switchgear, busbar systems, and protection systems.A grid substation is part of the electricity grid system -i.e. part of the transmission system. In the UK, this involves voltage levels of 400 kV, 275 kV, and 132 kV.
What is the need of under frequency relay in load shedding on power system?
when the load on a certain system increases the frequency of the system falls normally. It is dangerous to operate the equipments when the frequency is lower than the normal rated frequency so shed the when the frequency falls under voltage relays are used. I hope i answered your question :)
Why bus bar is rectangular?
Busbars are not necessarily rectangular. Those used in substation compounds are frequently tubular in construction.
What is function of CVT in Substation?
Capacitive voltage transformer (CVT) which is having special properties & used for protection & metering purpose.
What are the effects of load shedding on rural life?
The effects load shedding, or temporarily denying electric power to an area, are bad everywhere. People in the rural areas need electricity just as much as people in the urban areas do. Load shedding is prevalent mainly in developing countries, where there is a shortage of electric power generating capacity. In developed economies people are so used to using electricity in their homes (for lights, fans, A/C's, televisions, computers, etc) and their offices, and in their industries, they can hardly understand how devastating load shedding can be to being able to enjoy living a happy life.
Why are control panels used in substation?
Substation is the place (in transmission of power with overhead/underground cable) where the voltage level may be increased or decreased. That voltage level is so high that any personnel on its own cannot check/handle it by meters physically. Also the load on the system is never constant so there are fluctuations (ups/downs) in all the parameters of the electricity, like voltage, current, power factor (reactive and active power), frequency etc. So to calculate/estimate those things continuously with the time we need to implement separate monitors for them. This also implies that if any unacceptable change is observed in the power system, it should be immediately solved and continuity of power should be kept. That is the reason we go for control panels in substation. Now in control panels there are all the those things which are required for the measurement of voltage, current total power, frequency, power factor. These are measured at all time of the day. If any fault is observed in the measured readings, then it is cleared immediately, and if it is not able to clear it itself, then the personnel on the substation can clear it by switching off the certain power line through circuit breakers. CBs, relays, CTs, PTs, APFC all are incorporated in control panels. If still you are not clear with what is mentioned above, please feel free to ask me on dishant22@hotmail.com
What are the different types of relays used in substation?
kinds of electrical relays
Why solar panel can't be used to meet domestic need of electricity?
because the energy produced from the panels is just not enough to power a house load of energy!!
What are thermal panels?
Thermal panels are panels that are used to get other energy from heat. They are commonly used for water heating.
Type of transformers used in gas insulated substation?
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
What type of gas is used in a gas insulated substation?
sulphur hexa-fluouride
What are fabric panels used for?
Fabric panels can be used for a multitude of things. One of the best uses for fabric panels is to make quilts. Fabric panels can also be used to make creative gifts.
What is tertiary bus in substation?
Many substation transformers have three windings - the primary, secondary, and tertiary. The tertiary bus is the bus connected to the tertiary of the transformer. this is often used as station power for the substation, since the tertiary is very often a distribution level voltage (2 - 15kV).
What are polycarbonate panels used for?
Polycarbonate panels are used as substitutes for glass and plastic such as in windows. You can purchase polycarbonate panels from retailers such as Amazon.
What are the harmful effects of load shedding on computer?
It affects the student life a great deal. They cannot prepare for exams, print stuff out, submit online assessments. Now a days computers are used in various sectors like hospitals, online ticket reservations, Bank transactions etc. if all these computers are affected because of load shedding it will cause a big loss to the community.

Why the capacitive voltage transformer and voltage transformer both are used in a substation?
three phases
