The present invention provides means to instantaneously optimize reactive kva for an a.c. power system containing both linear and non-linear reactive loads. The preferred means utilizes a reflux transformer which is tuned for maximum energy transfer between primary and secondary windings. Each secondary winding is connected in series with a variable inductor and a fixed capacitive means, so as to continuously reflect variable reactive kva to the power system via the primary and secondary windings. The reactive kva requirements of the power system can thus be continuously optimized without destructive voltage transients associated with switching graduated units of fixed capacitive compensation or incurring the risk of conducting series resonant currents associated with non-linear loads.
