This field shall be the measured value for the given harmonic order.
For the Harmonic Currents attribute, this value is the most recently measured harmonic current reading in milliamps (mA). A positive value indicates that the measured harmonic current is positive, and a negative value indicates that the measured harmonic current is negative.
For the Harmonic Phases attribute, this value is the most recent phase of the given harmonic order
in millidegrees (mDeg). A positive value indicates that the measured phase is leading, and a negative value indicates that the measured phase is lagging.
If this measurement is not currently available, a value of null shall be returned.
This field shall be the order of the harmonic being measured. Typically this is an odd number, but servers may choose to report even harmonics.
