LXinstruments GmbH
Power electronics assemblies often cannot be tested using conventional technology for their electrical performance. Due to the adaptability of the instrumentation, the OTP concept offers an ideal platform even beyond the space requirements of several control cabinets. In order to achieve high test flexibility with different assemblies, the system was equipped with three-phase AC sources and AC loads as well as a precise three-phase power meter. DC sources and loads with different current and voltage ranges cover the test of frequent DUT operating parameters. Time-dependent voltage or current signals can be stimulated by an arbitrary generator with power amplifier. General measurements such as current, voltage, frequency, resistance can be carried out flexibly at various test points using the matrix concept. An oscilloscope with RF multiplexer is available for high-frequency measurements such as residual ripple, switching processes, etc.

The Power Supply Systems are the heart of any experiment. They provide the High voltage and Low voltage required by the detectors and by the related front-end electronics. The quality of the power supply is critical to obtain the best performance from the set-up. The sensibility of modern detectors, in fact, make them susceptible to any even small variation in the power supply, and so features like low Noise, low Ripple and high stability become essential in the design of a performing power supply system. Strong of 40 years of collaboration with the most important research labs worldwide CAEN offers today sophisticated High Voltage Power Supply and Low Voltage Power Supply Systems. The demonstration of this successful long-standing tradition is the “CMS Crystal Award 2009” that CAEN received for the development and production of the power system for the CMS tracker. CAEN offers a wide selection of Power Supplies in different form factors and standards:- For smaller set-ups Standalone or modular (NIM / VME) products or are the ideal fit.- For bigger set-ups, where a high number of High voltages and Low voltages is required, the Mainframe Systems and Boards (up to 48 channels/board, up to 768 channels in a single Mainframe) are the most recommended.

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.
