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.

use of CT
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
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.
A substation that is smaller than the average substation. A substation converts electric power from one voltage to another.
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.
The Substation which comes power from the power plant know as pooling substation.
I am sorry, but I think that this is impossible. It must have batteries to function.
Capacitive voltage transformer (CVT) which is having special properties & used for protection & metering purpose.
The Vulcan requires batteries to function, but does not come with the blaster. You have to keep buying new batteries, which is quite expensive.
It requires 2 AA batteries to use the laser function.
