Cvt Voltage Transformers

Our company is engaged in providing a wide assortment of CVT Voltage Transformers in Chennai, Tamil Nadu, India.

Advantages of CVT:
* No moving parts
* Overload protection
* Short circuit protection
* Spike rejection capabilities
* Faster voltage correction than servo stabilizers

Disadvantages of CVT:-
* Output voltage varies as a function of frequency unless a frequency compensating network is used. The output voltage will vary 1.6% for a variation of 1% (0.5 Hz) input frequency.
* Physical size & weight of a CVT is larger than a linear transformer of the same rating.
* There is a hum noise increases as the CVT rating increases.
* Very expensive when compared to Servo Stabilizers.

Recommendations:-
* Switch on CVT before switching ON the Load & while switching OFF switch, OFF Load first & then the CVT.
* Switch OFF CVT when not in use to save power.
* CVT cannot be used for an inductive load.
* Keep magnetic storage & display devices like diskettes, spools, monitors, etc. away from the CVT.
