You can configure three Calibrators to calibrate a three-phase power meter. This example
uses the assumption that you want to apply a perfectly balanced calibration output with a
unity power factor. By changing the phase relationships, you can apply other test
stimulus. The figure shows the phase relationship of each Calibrator. By changing the
phase relationships, you can apply other test stimulus.
