• CVT'S response to input variation is much faster than that of servo stabilizer.Around 10msec. 
• CVT does not pass on the surges to the output side which are present on the input side. 
• CVT has no moving parts at all, thus bringing maintenance cost to almost zero. 
• CVT combines all the features of an isolation transformer, surge supressor &RFI-EMI Fliter, thus bringing down the cost. 
• CVT has inbuilt instantaneous short circuit protection. 
• CVT us highly reliable. 

Working Principle of a CVT

CVT uses the principle of ferro-resonance in which ouput winding is resonated with the help of select value of high stability capacitors. This resonating circuit gives rise to saturation of the core which prevents variation in the output against changes in the input voltage.
