How cvt works and its applications with some technical reference

RE: CVT APPLICATIONS

A CVT is basically a voltage transformer, that uses a capacitive voltage divider to step the voltage down to 6-15 kV and then uses a conventional core/coil xfmr to further reduce the voltage to the normal 115/69 V (110/sqrt3 V for IEC).

The official name is CCVT, which stands for coupling capcitor voltage transformer. The capacitance to ground inherent in the device can also be used to couple power line carrier signals to transmission line voltages.

Refer to instrument transformer manufacturer's web sites for more information. One good one is www.ritzusa.com. They post all of their technical information in their catalog section.

RE: CVT APPLICATIONS

There is a saying that goes "If you give a man a fish, you feed him for one day.  If you teach him to fish, you feed him for a lifetime".  Here's a fishing lesson -

- Go to the search function on your internet browser.
- Enter the keywords that you want information on (in this case, CAPACITIVE+VOLTAGE+TRANSFORMER)
- Submit the search and browse the results to find what you are looking for

Alternatively, pay attention in class.

RE: CVT APPLICATIONS

CVT can also stand for constant voltage transformer.
(like a sola or ferroresonant).

Searching will work in that case also.

RE: CVT APPLICATIONS

electricpete is right...constant voltage transformer..or ferroresonant..

SOLA is one of the most popular manufacturer..

it is a combination of AC capacitors and inductors and by cleverly connecting them becomes a "voltage regulator" at resonant frequency...say 60 hertz...very rugged although a bit expensive..

...an unintentional short on the output creates overcurrent on the line side which eventually opens the protection but no severe damage on the CVT itself...i did lots of test like this years ago...500VA to 5 kva.
