RMO-G Series

Contact resistance measurement is one of the most important and common tests during switchgear manufacturing, commissioning and maintenance stages. Besides switchgear testing, the RMO digital micro-ohmmeters are designed for simple, safe and efficient testing of:

  • disconnecting switches,
  • high-current bus bar joints,
  • cable splices,
  • welding joints,
  • and different high-current links in factory and high-induction field environments.

Description

RMO_G Series is a micro ohmmeter that is used for contact resistance measurement in the following condition.

  • disconnecting switches,
  • high-current bus bar joints,
  • cable splices,
  • welding joints,
  • and different high-current links in factory and high-induction field environments.

All DV Power RMO micro-ohmmeters use Kelvin’s 4-point measurement principle which is the most convenient for very small resistance measurements. The measurements are accurate and in accordance with international standards for AC high-voltage circuit breakers testing (IEEE C37.09 and IEC 62271-100).

Starting from 2003, DV Power has been a trend-setter on the market when our first 500 A micro-ohmmeter weighing only 8 kg (RMO500A / CPM500) was released.

Currently, DV Power products portfolio includes 16 models, divided into 3 series:

  • 13 portable models: RMO-A (6) and RMO-G (7) series.
  • 3 handheld models: RMO-H (3) series

The instruments generate a user-selectable and ripple-free test current up to 800 A in an automatically regulated test ramp. Test current ramping significantly decreases the influence of the magnetic transients to measurement.
