Reverse power protection (REVPOW)
Reverse power protection (REVPOW) is used to save the motor from the damage by detecting
the reverse power regarding active power and reactive power. The REVPOW function consists
of reverse active power protection (RP) and reverse reactive power protection (RQ). They have
two independent stages (i.e., independent elements). To simplify the description hereafter, the
first of two stages is only discussed, but the expression is applicable to the second one.
