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

Rated Standard Voltage	Rated Voltage Winding 1	Rated Current Winding 1	Rated Voltage Winding 2	Rated Voltage Winding 3
Applied	Measured	Measured	Measured	Measured
Rated AC Voltage	V1	I1	V2	V3

Mutual Reactance = V₂ / I₁

                                  OR

                              = V₃ / I₁
