Product Overview

The Orion M1 phase comparator and mobile test and display unit from HORSTMANN is designed for voltage testing, phase comparison, and coupling part testing according to IEC 61243-5 on LRM and HR interfaces for medium-voltage switchgear. The Orion M1 features a high-contrast illuminated LCD screen, an integrated USB interface for reading stored measurements, and built-in safety functions such as automatic self-testing and visual/audible signaling.

Main Functions

  • Mobile test and display unit for voltage testing, phase comparison, and coupling part testing.
  • Illuminated LCD display for reading interface current, phase angle, and harmonics in accordance with EN 50160.
  • Measurement functions include FFT, total harmonic distortion (THD), and harmonics up to the 40th. Rotating field indicator with status RGB-LED.
  • Storage of measurement results and data transfer via integrated USB interface.
  • Selectable mains frequency (16.7 Hz / 50 Hz / 60 Hz) and language selection (German/English) in the menu.

Typical Applications

  • Voltage testing on LRM and HR interfaces for medium-voltage switchgear.
  • Phase comparison including display of phase difference and phase equality symbol.
  • Coupling-part testing in accordance with IEC 61243-5.
