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.


What is the principle of transformer?

A transformer relies on electromagnetic coupling to transfer power between two electrically isolated circuits. The transformer may step-up or step-doen the voltage or even perform 1:1 transformation for isolation purposes.


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 a transformer that increases voltage?

A transformer that increases voltage is a step-up transformer.


Why transformer coupled amplifier is more efficient than RC coupled amplifier?

an RC coupled amplifier is basically used for voltage amplification , where the circuit currents are quite low. higher currents & voltages would mean more dissipation in the load resistors , which is essentially very lossy . The coupling amplitude to the next stage is ideally the same as the previous stage signal excursion. However if a transformer is used for coupling , both large voltages & current can be handled without incurring the dissipation of a resistive load. Moreover a coupling gain of the transformer primary to secondary ratio is also a bonus. also because of the possiblity of correct impedance matching on the primary & secondary side maximum power coupling is obtained. hence transformer coupling is more efficient in such applications. in high frequency applications transformer coupling , along with tuned circuits as applicable is the choice circuit.

What is the difference between a secondary and primary coil?

The primary coil is the one with voltage applied, or the 'input'. The secondary coil is the one in which a voltage is induced by electromagnetism, or the 'output'. In a step up transformer, the secondary coil voltage is higher than the primary. In a step down transformer, the secondary coil voltage is lower than the primary. In an isolation transformer, the secondary coil voltage is the same as the primary. Here, the point of the transformer isn't to raise or lower voltage, but to keep a particular circuit electrically disconnected from another circuit, while still allowing the circuits to function together (through electromagnetism).

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.

What is the primary function of a step-down transformer that distinguishes it from a step-up transformer?

A step-down transformer reduces the voltage from a higher level to a lower level, while a step-up transformer increases the voltage from a lower level to a higher level.
