Model 40/15 -
TREK, INC.
The Model 40/15 is a DC-stable, high-voltage power amplifier featuring an all solid-state design for high slewrate, wide bandwidth, and low-noise operation. It is configured as noninverting with a fixed gain of 4000 V/V and is protected against overvoltage and overcurrent conditions that may be generated by active loads or by output short circuits to ground. Precision voltage and current monitors provide low-voltage representations of the high-voltage output and load current for monitoring purposes or for use as feedback signals in a closed-loop system.

FTL testblock with dust cover and current disconnect pinThe FTL is a test block for interfacing substation devices (protection relays, fault recorders, revenue meters, ... ) to the voltage and current transformers and to other equipment on the system side of a power grid. The FTL test block uses disconnect pins to isolate the substation devices from the system side equipment. Once isolated, secondary injection can be performed using banana jacks on the front side of the test block.

RMO-A Series -
IBEKO Power AB
The RMO-A is a portable micro-ohmmeter designed for contact resistance measurements of switchgear during manufacturing, commissioning and maintenance stages. This micro-ohmmeter is widely used by medium and high-voltage circuit breakers manufacturers. Other typical applications are testing of disconnecting switches, high-current bus bar joints, cable splices, and different high-current links. It accurately measures not only in factory environments but also in high-induction fields and substationsThe RMO-A series contains 6 models, rated from 100 A (RMO100A) to 600 A (RMO600A). The RMO500A (formerly CPM500) is our best seller, with 500 A ripple-free current and weighs only 8 kg.Although placed in a very portable and lightweight metal housing, RMO-A micro-ohmmeters have very high output power capabilities. They can generate 600 A test current continuously for up to 20 s. You can test with current up to 100 A without rest time. High output voltage enables a wider measurement range at the highest test currents, as well as the use of thinner/longer test cables. For testing with 100 A, 20 m test leads can be provided with only 16 mm2 cross-section.RMO-A micro-ohmmeter generates a true DC ripple-free (less than 1 %) current with automatically regulated test ramps. During a test, the RMO-A ramps up with increasing current before measuring and decreasing current after the measurement. This significantly decreases magnetic transients and ensures great accuracy.An additional option is a built-in High Precision module suitable for measurement of very low resistances, ranges from 1 to 30 µΩ, with 0,01 µΩ resolution.These instruments can store up to 500 measurements in internal memory. A built-in thermal printer is available as an option.Our free DV Win software communicates with the RMO-A micro-ohmmeters via USB or RS232 interface. It allows you to run the test remotely from PC, as well as to download test results, analyze and generate fully configurable test reports.

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.
