Question

write a short note on constant voltage transformer​

Answer 1

Answer:The very best power protection comes from a special type of transformer known as a Constant Voltage Transformer ( CVT). Providing unparalleled reliability and conditioning performance, spikes and electrical noise are neutralised with attenuation as high as 75dB.

In addition the input (or primary) and output (or secondary) transformer windings are physically separated. Known as Galvanic isolation this separation ensures that there is no direct connection between the mains supply and load.

A CVT therefore provides an impenetrable barrier to spikes and high frequency electrical noise. This barrier also works in reverse mode to prevent a 'noisy' load from polluting the mains supply itself.
