Power Quality Analyser
LDVRC is used to compensate the voltage disturbance that is relatively long time and shallow amplitude. When the protected equipment need a very stable voltage(≤5% of rating voltage), LDVRC is applicable. LDVRC is proposed to be used to solve the problems of short time voltage disturbance and deep sag.
