Orion 3.1 — Phase Comparator and Voltage Tester
The Orion 3.1 from HORSTMANN is a mobile testing and display unit for voltage testing, phase comparison, and coupling part testing on LRM and HR interfaces for medium-voltage switchgear in accordance with IEC 61243-5. The unit provides voltage display and rotating field direction, and includes visual and acoustic signals and automatic self-testing for operational safety.
Function and Design
The Orion 3.1 is designed as a handheld measuring device with a compact housing and ergonomic design. It supports nominal frequencies of 16.7 Hz, 50 Hz, and 60 Hz, and the input impedance is specified at 2.0 MΩ (±2 %). The unit is powered by four AA (LR6) cells.
Typical Applications
- Used for voltage testing on LRM and HR interfaces in medium-voltage switchgear.
- Used for phase comparison (rotating field direction) on the specified interfaces.
- Used for coupling part testing on LRM/HR interfaces.
