Micro-Ohmmeters
-
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.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.6 handheld models: RMO-H (6) seriesThe 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.

Short Circuit Locator for Power Cables
A910
-
The A910 is a short circuit locator designed for fault location in power cables. The instrument measures the ratio of the resistances of the two sections of failed conductor using a four-wire "Kelvin" connection, thus eliminating errors associated with contact resistances of the test leads. With the A910 you can determine if the cable has more than a short and locate the first and the last fault. The instrument locates fault with an insulation resistance up to 5 Mohms in cables that have a total resistance greater than 5mohm (approximately 90 m of 300 sqmm cable) and less than 30 kohms. The distance to fault is measured as a percentage of the total length of cable and is displayed on a large LCD display.
