Megger Programma ODEN AT 22,000A primary injection test set. With 208/240/480 auto transformer, the control unit has many advanced features and a powerful measurement section for example, that can display turns ratio as well as time, voltage and current. A second measurement channel can be used to measure an additional current or voltage. Current transformer turns ratio, impedance, resistance, power, power factor (cos f) and phase angle are calculated and shown in the display. Current and voltage can be presented as percentages of nominal value.
