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.
What else can I help you with?
What is the basic function of chopper circuit?
to convert the DC into DC.............
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 does AC-DC conversion and battery charging mean?
The voltage in your house is AC. It is in the form of a sine wave that goes positive and negative 60 times a second. To charge a battery you need DC so you do an AC to DC conversion and then apply the DC to the battery charging circuit that applies the correct charging current to the battery and checks on the state of the charge.
What can a DC voltage be produced by?
A: AC recitification and battery source.
Will a car DC inverter kill your battery?
Anything left plugged in and powered up can drain the battery.
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
Is Battery is DC or AC?
An alkaline battery's output is DC as is any battery.
How is an electrical substation's NiCd battery bank commissioned?
Very carefully
What is the main function of a current transformer in switchyard substation?
use of CT
Is battery ac or DC?
Batteries are DC
Why DC is used in battery's?
dc in battery stands for direct current .ac is alternating current.
What is uninterruptible?
DC, or direct current, such as from a battery or a DC generator.
What does dc-in stand for?
DC can stand for "direct current" which is what you get from a battery. dc-in would be a connection for DC input.
How can you on laptop wihtout using battery?
we can use a dc voltage directly from a dc source with parameters equal that of the battery
Can I use a battery charger that is rated at 6V DC 1000 mA to replace one that was 6V DC 100mA or will this damage the battery?
No you should not do that. It will damage the battery and the battery will explode.
What is the function of battery bank in a substation?
a very helpful functionAnswerBatteries 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.
Is a car battery AC or DC volts?
dc - the voltage is a constant 12 volts nominally in a normal car battery.
