The Megger 550050 calibration reference transformer is used to help ensure the accuracy of a Megger 550005B single-phase hand-cranked transformer turns ratio set (sold separately). The transformer provides a reference standard for periodic calibration checks of the transformer turns ratio set to increase the accuracy of the TTR. The 550050 is used by electricians and electrical contractors to test the accuracy of a 550005B.
