Voltage current transformer model meaning

Capacitive voltage transformer (CVT), in 1970 developed the domestic first 330 KVCVT, 1980 and 1985, developed the first generation and second generation KVCVT 500, electric motor 12v 500w 1990 and 1995, developed the third and fourth generation KVCVT 500, more than 30 years has accumulated rich experience in scientific research, development, design and production, in the domestic developed generation after generation of CVT new products, giving impetus to the development of www.dongfeng-motor.com the domestic CVT. CVT's main features are: High - electric strength, insulation margin is large, reliable operation. - can reliable damping ferroresonance. Successful adoption of the new group phase, with strict quality control, ensure that the factory's every fan motor piece of CVT are under any ac motor of the voltage from low to high effective damping various ferromagnetic resonance frequency. - good contact response characteristics. When the second time remaining after a short circuit voltage can fall below 5% in 20 ms, especially adapted to the fast relay protection. With power grid harmonic monitoring of patent technology.
