 7.3.5.1  RVC, Ripple control

The RVC threshold (or thresholds) and the RVC hysteresis are both set by the user according to the use.
Mains signaling voltage, called “ripple control signal” in certain applications, is a burst of signals, often applied at a
non-harmonic frequency, that remotely control industrial equipment, revenue meters, and other devices.
