a very helpful function
AnswerBatteries 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.

What is the main function of auxiliary transforme in a substation?
auxiliary transformer is used to supply low voltage for AC power system inside substation such as lighting ,air conditioners and other AC supply system and DC power system such as protection relays, batteries, SCADA & telecom system and other DC supply system
Why is a DC voltage supply used for energizing the tripping coil of an air circuit breaker?
If a fault in the system disconnects the substation, then batteries are the only supply available to trip the circuit breakers. Batteries, of course, are d.c.
What is a mini-substation?
A substation that is smaller than the average substation. A substation converts electric power from one voltage to another.
Why DC source is required for a breaker?
A high-voltage circuit breaker's trip coil is normally operated from a d.c. supply -provided by a bank of batteries located in the substation. This ensures that, in the event of a total loss of a.c. power to the substation, the protection system remains effective.
What is pooling substation?
The Substation which comes power from the power plant know as pooling substation.
How do you charge a camera with no charger or batteries?
I am sorry, but I think that this is impossible. It must have batteries to function.
What is function of CVT in Substation?
Capacitive voltage transformer (CVT) which is having special properties & used for protection & metering purpose.
Does Nerf vulcan have batteries?
The Vulcan requires batteries to function, but does not come with the blaster. You have to keep buying new batteries, which is quite expensive.
Which batteries do you need for the Nerf nightfinder?
It requires 2 AA batteries to use the laser function.
