- RMO-G series of Micro Ohmmeters (hereafter referred to as “RMO-G”) contain 7 models: RMO100G, RMO200G, RMO300G, RMO400G, RMO500G, RMO600G and RMO800G.The main difference between these models is the maximum test current that can be generated
- Ingress protection rating: IP67*with closed lid
- Application:Typical application is measuring resistance of non-inductive test objects:
- High, middle and low voltage circuit breakers (live and dead tank)
- High, middle and low voltage disconnecting switches
- Gas Isolated Switchgears (GIS)
- High-current bus bar joints
- Cable splices
- Welding joints
- Fuses
- System Overview:
- RMO-G generates a true DC ripple-free current with automatically regulated test ramps. During a test the RMO-G ramps with increasing current before measuring and decreasing current after the measurement. This eliminates magnetic transients.
- The RMO-G instrument can store internally up to 500 measurements. All measurements are time and date stamped.
- Using the DV-Win software a test can be performed from a user’s PC, and the results can be obtained directly on the PC.
- Communication between the RMO-G and a PC is through an USB (as standard) or an RS232 cable (as an option). Bluetooth communication interface is also available as an option.
- Using the DV-Win the result can be arranged as an Excel spread-sheet which can be later shown as a diagram and printed for a report.
- The set is equipped with a thermal and an overcurrent protection. The RMO-G has a very high ability to cancel electrostatic and electro-magnetic interference in HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing a proprietary hardware and software.
