RMO-TD Series -
IBEKO Power AB
Using the most advanced switch-mode technology available today, the RMO-TD series is ideal for winding resistance measurements of inductive objects. Transformer resistance meters and tap changer analyzers are perfect for testing:transformer windings (power transformers, distribution, autotransformers),all types of tap changers,generators,electrical motors,high-current busbar joints,cable splices,and welding joints.In addition, transformer demagnetization can also be done with all RMO-TD instruments.The RMO-TD series contains 3 models, with maximal test currents from 25 A (RMO25TD) to 60 A (RMO60TD).The three independent voltage sense channels enable testing of three windings in series. This enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.All RMO-TD transformer resistance meters have a built-in tap changer control unit. It enables remote control of on-load tap changer (OLTC) directly from the device. In order to make the most out of this feature, DV-Win software is included which can be programmed to do everything automatically – running winding resistance tests and changing OLTC tap positions.The DV-Win software also enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test.All results can be exported in the report format.

Hawk® EMS -
International Medcom
The Hawk® EMS is a wall or tripod-mounted radiation monitoring and alarm system designed for use with the Hawk® Radius dual sensor radiation probe. Each EMS System comes with a Hawk Radius Probe. The system is extremely energy efficient and can run for weeks on an internal 9 volt back-up battery if power fails. It is well suited for operating on a small solar panel, which is an optional accessory. The Hawk® EMS features two displays that show the radiation levels measured by each of the probe’s two detectors: the weatherized “pancake-style” Geiger-Mueller tube — which measures alpha (if configured for it), beta, low energy gamma, and x-radiation — and the energy-compensated gamma tube which measures penetrating gamma dose rate. The probe can be mounted next to the EMS system or outdoors, or in adjacent rooms on cables up to 100 ft in length. Standard cable is 3 meters in length. Optional signal booster can support cable lengths longer than 100 feet. Optionally the system can also be configured to share data on ethernet or wireless networks.

PSE Instruments GmbH
A comprehensive analysis of PV modules includes many different parameters. Determining the normal module operating temperature (NMOT), incidence angle effects and comparing soiling effects on different modules up to the initial degradation of PV modules are all parameters that can be analyzed with our outdoor exposure tester. The tester comes with up to twelve electronic loads installed in a 19" rack. The loads have two main functions: maximum power point tracking (MPPT) and IV curve tracing. For the advanced analysis, it is possible to change between these two modes within one test. In the normal operation mode, the electronic load keeps the module under MPP and each predefined interval an IV curve is traced. The entire tester comes with all necessary sensors such as temperature sensor, which can be attached to the module to determine the NMOT temperature like defined in IEC 61215 (MQT 05) and IEC 61853-2. The irradiation sensor is also included. In combination with our tracking system P2, it is also possible to determine incident angle effects of the PV module. It is also possible to connect other irradiation sensors for diffuse and direct irradiation, which helps to understand the behavior of the module in different irradiation conditions. An optional albedo meter is a powerful tool for the analysis of bifacial modules. The entire graphical user interface is web based and offers the possibility to access the system from the all computers in the network.
