What voltage is used for control circuits?
voltage
What is the voltage that supplies a motor starter called?
In the electrical trade it is called control voltage. This voltage can be any voltage. In North America the common control voltage is 120 volts.
How does voltage fluctuation affect an electrical system?
Whenever you are working over a device and getting a constant voltage supply ,, and all of a sudden .. the light gets off and the device is off. it means a device was working over some specified voltage and it comes to 0 instantly . the voltage changes . this is called voltage fluctuation .
What are 2 advantages for this particular control voltage?
With voltage control there is so much voltage drop due to resistor, that's the disadvantage
What would the control voltage be for a transformer marked 240v 24vac?
A control transformer marked 240V - 24Vac would have a control voltage of 24 volts.
Is there a fluctuation of voltage in a moving train?
Yes, there is a fluctuation of voltage in a moving train
Why UPS is required in Distributed Control System?
to maintain control voltage during power loss or spike
What is voltage fluctuation?
A: Due to undesirable external voltage changes like the AC line dropping out occasionally the DC or input signal will become a variable voltage that is referred as voltage fluctuation but it can refers to all kinds of these kind of problems.
How can you prevent this fluctuation of electricity from damaging your computer?
Use UPS to supply power.UPS is Uninterrupted Power Supply hence it works in fluctuation too.
What is the enemy of electrical components in a computer?
surely , voltage fluctuation Heat
What helps protect the computer against power fluctuation?
UPS (uninterruptible power supply)
What is the amps of a 650 VA UPS?
To answer this question the voltage of the UPS has to be stated. Take that voltage and divide it into the 650 rating. The answer will be the output amperage of the UPS.
Function of power supply?
to convert AC into DC voltage without fluctuation
How do you regulate the input voltage for a ups?
You can regulate the input voltage for a UPS using additional line filtering techniques.
What is a common source of IC damage in a computer?
Fluctuation in voltage of current and excessive heat
What would do a ups battery back up connected to a control board of a traction elevator if power is lost?
nothing only will control board on low voltage will continue energized
What is rtcc pannel?
RTCC (Remote tap changer control) panel is one of the LT panel which has microcontroller, contactors, relays etc it senses the fluctuation in distribution voltage (input of Transformer) & give signal to OLTC to change the voltage(Output of the transformer) to set a value
