To Measure Mutual Reactance of The Three Phase Reactor


The mutual reactance of three phase reactor is measured by following methods.
Steps
  • Rated voltage is applied at one winding
  • Rated voltage and current is measured at one winding
  • Rated voltage is measured at all remaining winding

Mutual Reactance = V2 / I1
                                  OR
                              = V3 / I1
