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 the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
What is the range of circuit breaker that can be used for a 24V DC equipment?
Use a fuse
What are DC Choppers?
Dc chopper is a static device which converts constant dc source to variable dc.
Can an AC circuit breakers be used on a DC circuit and will this give that circuit adequate protection?
Check the nameplate on the actual breaker. Some breakers are rated for AC or DC. If it doesn't specifically list DC on the nameplate, then no, you should not rely on the breaker to adequately protect the circuit.
What happened to DC voltage source which is in series with AC voltage source?
The two sources add together, imposing a DC bias to the AC source.
What happens if you use an ac circuit breaker instead of dc breaker?
A circuit breaker is easier to design for ac than dc because alternating current (ac) naturally goes to zero 100 or 120 times per second and this helps to extinguish any arc. Therefore an ac circuit breaker would not be suitable for dc assuming the same voltage and current ratings.
How do you charge a supercapacitor?
use a dc power source. preferably an ac/dc power adapter. any dc power source will do.
What is the different between ac dc motors?
DC Motor works on DC source and AC motor works on AC source
What happens when an ac transformer attached to ac appliance is plugged into dc power source?
it depends on the transformer size and the period of time involved if continuous it should just blow the breaker and itself.
What is the range of circuit breaker that can be used for a 24V DC equipment?
Use a fuse
When setting up a breaker box how do you determine circuit breaker capacity?
find amphere required
What are DC Choppers?
Dc chopper is a static device which converts constant dc source to variable dc.
What is an dc meachine?
it is a machine which operates on the dc power source.
What is a motor design that works with either an AC source or a DC source?
A variable speed module in a motor can work with ac or dc source
