The function of a CVT is to provide a secondary voltage to equipment that is a direct ratio of a much higher primary voltage. They can also be used to couple communication signals onto transmission lines.

What is the function of capacitor voltage transformer at the switch yard?
function of capacitive voltage transformer is measure high transmission voltage with low range voltmeter and oprate the relay circuit to oprate CBs.
Why transformer is only used instead of any other device?
A transformer is the primary device which transforms voltage to a higher or lower voltage. In electronics, capacitors and resistors perform this function.
What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a full rectifier circuit with a filter capacitor?
25.46V assuming output of transformer is pure sinewave.
Why is voltage rating of a capacitor important to the user?
The voltage rating of a capacitor tells the user how much voltage the capacitor can withstand. If a user exceeds this voltage, the capacitor's dielectric may be damaged and destroyed.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.

What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?
The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
The basic function of a transformer is to change?
The basic function of a transformer is to change voltage levels.
What function does a capacitor serve in an auto transformer?
An autotransformer does not normally use any capacitors as it is a transformer with one winding and the lower voltage is taken from a tap part-way up the winding. A capacitor could be added if there is a concern about the power factor presented by the autotransformer to the supply.
What two facctors determine the capacitive reactance of a capacitor?
The reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the capacitor
How a capacitor steps down ac?
A capacitor doesn't step down AC voltage, that's what a transformer does! It really can't, no matter what the circumstances.
What is the purpose of transforms?
A transformer is used to step up or step down a Voltage supply.
How do you produce a step-up transformer in an ordinary transformer?
Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.
What is the main function of the transformer?
step up transformer output gives the high voltage which is useful for transmiission of electricity

What are the voaltg in isolation transformer?
The function of an isolation transformer is to electrically-isolate the secondary circuit from the primary circuit, without changing the voltage levels. So, its secondary voltage will be the same as the primary voltage.
How you can choose the capacitor range for 24 volt output rectifier?
the high quality way is to rate the capacitor for: 2 times the DC voltage. or 2 times the peak voltage of the transformer. Consumer Industry does not care about prpoduct life span and accepts much less conservative "bare minimum" ratings to reduce cost: 1.5 times the DC voltage. or 10% higher than the peak voltage of the transformer A good 24V supply has a 35V capacitor. Of course the cheaply made product will fail sometime with such narrow margin.
