GGT Series -
IBEKO Power AB
The GGT500 ground grid integrity tester is designed for inspection of the substation ground grid. It can also be used as a portable micro-ohmmeter with Both Sides Grounded and Remote Control functionalities. It is intended to inspection the conditions of a grounding system beneath substations, testing of medium- and high-voltage circuit breakers, disconnecting switches, high-current bus bar joints, cable splices, and different high-current links.In the United States when inspecting the quality of the grounding systems beneath a substation, the proper procedure is to inject 300 A DC during a time period of 60 s. This is what the GGT500 will do, and in that time period, the current path and voltage drop are checked. Also acting as a micro-ohmmeter, the GGT500 can test low resistance values by producing high test currents of up to 500 A.The instrument is placed in an unbreakable, plastic case with IP67 protective rating (with closed lid). Although very portable and lightweight, micro-ohmmeters have very high output power capabilities. High output voltage enables a wider measurement range at higher test currents, as well as the use of thinner/longer test cables. GGT500 ground grid integrity tester generates a true DC ripple-free (less than 1 % ripple) current with automatically regulated test ramps. This significantly decreases magnetic transients and ensures great accuracy.When used for testing in Both Sides Grounded conditions, a special current clamp powered from the ground grid integrity tester is used for measuring a current through groundings. If even a higher safety level is required, the remote control feature enables the operator to perform measurements from a distant location, away from the instrument and test object.

IBEKO Power AB
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.

RMO-E Series -
IBEKO Power AB
The RMO-E instruments are designed and ideal for testing protective bonding (grounding) of equipment following the standard IEC 61010-1. Also, they can measure the resistance of high, middle and low voltage circuit breakers, high-current bus bar joints, cable splices, and welding joints. The instruments accurately measure not only in factory environments but also in high-induction fields and substations.Both models generate a true DC ripple-free (less than 1 %) current with automatically regulated test ramps. During a test, the protective bonding testers automatically generate increasing current before measuring and decreasing current after the measurement. Consequently, this significantly decreases magnetic transients and ensures great accuracy.These instruments can store up to 500 measurements in the internal memory and have a built-in thermal printer available as an option.DV Win software communicates with the RMO-E earth resistance meter via USB or RS232 interface. It allows a user to run the test remotely from PC, as well as to download test results, analyze and generate fully configurable test reports.The RMO-E series contains two models, RMO60E and RMO100E. The main difference between these two models is in the maximal test current:60 A DC for RMO60E100 A DC for RMO100E
