RAGNAR is suited for relay testing in situations where current, voltage and phase angle must be varied independently
Programmauited for relay testing in situations where current, voltage and phase angle must be varied independently. It extends the application range of the company's relay testing units SVERKER 750 and SVERKER 650. When the shifter is used with either of these, users can test both directional overcurrent protections and impedance protections. The relay testing unit's variable current passes through the shifter, where it provides an accurate voltage phase-angle reference. The voltage can then be varied up to 105 V, and the phase angle can be varied from 0 to 360°.
