The maximum current that flows when there is a short circuit in the substation.
CommentThis is not strictly-speaking true, as fault levels are expressed in MV.A, not in amperes, but it does allow the value of likely fault currents to be calculated.
A substation that is smaller than the average substation. A substation converts electric power from one voltage to another.
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).
The Substation which comes power from the power plant know as pooling substation.
In my line of work that is an Electrical High Voltage substation that is brand new. It is being built from a green field into an energized fully functional substation yard. There is no existing substation or remodeling of an existing one being done.
The world biggest distribution substation is in DELHI TRANS CO .
A substation is not a load but is a place where switching and voltage-level changing takes place. Accordingly, you cannot apply a 'power factor' to a substation.
Batteries are essential components in a substation. They provide the (tripping) current by which protective relays can trip high-voltage circuit breakers in the event of a fault. This means that the circuit breakers can trip even if the substation itself has lost its ancillary AC power supply.

Jefferson Substation was created in 1909.
Neuhof Substation was created in 1985.
Concourse Yard Substation was created in 1933.
The main purpose of earthing electrical circuits is to provide a low-impedance route back to the substation transformer which, in the event of an earth-fault will allow sufficient fault current to flow in order to operate a circuit's overcurrent protection.
