Orion 3.1 and Orion M1 are testing and indication devices for voltage detection, phase comparison and coupling part maintenance testing according to IEC 61243-5. They are used at LRM and HR interfaces in medium voltage switchgears. The Orion M1 features a large LCD display with backlight. It allows easy reading of the measured values, e. g. interface current, phase angle and voltage harmonics (according to EN 50160). The integrated USB interface is used to retrieve the stored data results for further evaluation.
