Under voltage ride through
In electrical power engineering, fault ride through (FRT), sometimes under-voltage ride through (UVRT), or low voltage ride through (LVRT), is the capability of electric generators to stay connected in short periods of lower electric network voltage (cf. voltage sag). It is needed at distribution level (wind parks, PV … See more Many generator designs use electric current flowing through windings to produce the magnetic field on which the motor or generator operates.
