DV Power RMO-H3 Micro Ohmmeter

Current transformer testing, calibration and assessment

The DV Power RMO-H3 Micro Ohmmeter generates up to 300 A DC (ripple-free) test current, user selectable and generated in an automatic regulated test ramp. This revolution in handheld micro ohmmeters technology is enabled by use of Li-Po batteries.

Ratings and Specifications

• Maximum test current rating: up to 300 A DC
• Intended for use with short type cables (e.g. 1,3 m)
• Li-Po (User-replaceable) 1-cell battery, 8800 mAh
• Applications

Typical application is accurate low resistance measurement during manufacturing, commissioning and maintenance inspections on:

• High and medium voltage Switchgears and Circuit Breakers (as per IEC 62271-100 standards)
• High and medium voltage Disconnecting Switches (as per IEC 62271-100 standards)
• High-current Busbar joints
• Terminals of the conductors on HV power lines
• Bonding of Lighting conductors

RMO-H instruments are also ideal testing tools for quality control checking during the production process of high-voltage equipment and equipment used in railway and aircraft industry:

• Welding joints
• Cable splices and cable resistance
• OLTC contacts checking (off-line, not connected to transformer)
• Railway joints, lines and conductor rails
• Bonds and joints checking in aircraft manufacturing industry
