A wide range of three phase current or current and voltage sources allow testing over the complete load range.
The PPS 3.3 genX is a powerful and portable three-phase current and voltage source. All test values are generated absolutely synthetically with a high degree of accuracy and stability.
The PPS 400.3 is a powerful and portable threephase current and voltage source. All test values are generated absolutely synthetically with a high degree of accuracy and stability. Following the different demands of customers, this source is available in two versions, for the supply of transformer meters with a maximum current up to 12 A as well as wider range source up to 120 A. The PPS 400.3 portable power source may be used
The CheckSource 2.3 is a three-phase current source for currents up to 6 A. The test currents are generated with the same frequency and a user-defined phase shift to the voltages applied to the voltage inputs (phantom load). Alternatively the test currents can also be generated with a user defined frequency.
