Potential Transformer is designed for monitoring single-
phase and three-phase power line voltages in power metering
applications.
The primary terminals can be connected either in line-to-
line or in line-to-neutral configuration. Fused transformer
models are designated by a suffix of "F" for one fuse
or "FF" for two fuses.
A capacitor voltage transformer (CVT), or capacitance
coupled voltage transformer (CCVT) is a transformer used in
power systems to step down extra high voltage signals and
provide a low voltage signal, for measurement or to operate
a protective relay.
