Among other things, solar array simulators are required for testing satellite power supplies. An SAS (Solar Array Simulator), consisting of an interconnection of several Solar Array Simulator modules, maps the solar panels and displays the individual strings connected in parallel. Optionally, the individual SAS modules are monitored by a Second Level Protection, so that the test object is not damaged in case of errors with the voltage sources. Additional circuitry is implemented via project-specific test modules. The signal path to the DUT can be separated, e.g. for dynamic current measurements.The Keysight Solar Array Simulators used were specially developed for satellite applications and cover the significantly higher requirements regarding the control speed of MPP tracking compared to terrestrial applications.

TRT Standard Series -
IBEKO Power AB
When it comes to choosing a transformer turns ratio tester, TRT Standard series offers some of the most advanced instruments with LCD display out in the market. Each model measures transformer excitation current and phase shift performs automatic vector group detection and magnetic balance on three-phase transformers and three-phase autotransformers. Furthermore, they have a built-in true three-phase power source. Because of that, TRT Standard instruments can test transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.The instruments can output test voltages from 1 V AC to 250 V AC, depending on the chosen model. High test voltage of 250 V AC provides more accurate turns ratio testing compared to other turns ratio testers on the market and extremely low test voltage of 1 V AC enables turns ratio verification of current transformers.TRT Standard series consists of:TRT03 Models (TRT03A, TRT03B, TRT03C) – single-phase voltage up to 100 VTRT3x Models (TRT30A, TRT30B, TRT30C, TRT33A, TRT33B, TRT33C) – single and true three-phase voltage up to 100 VTRT63 Models (TRT63A, TRT63B, TRT63C) – single and true three-phase voltage up to 250 VMore about models differences can be found under the downloads tab, in brochures and comparison sheets.A user can create test templates using the DV Win software and store them in the PC’s memory for later use when in the field.TRT Standard series models have a built-in tap changer control unit. Consequently, it enables remote control of an on-load tap changer (OLTC) directly from the tester. In order to make the most out of this feature, the DV-Win software can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions and saving results. This option, especially in combination with test templates, significantly facilitates and shortens the turns ratio testing time.

Transformer turns ratio testers from TRT series are DV Power instruments mainly designed for the measurement of power transformer turns ratio. Also, they measure transformer excitation current and phase shift. Special tests, such as automatic vector group detection and magnetic balance, can be performed on three-phase transformers and three-phase autotransformers.All models, except TRT03 series, have a built-in true three-phase power source, which is necessary for testing turns ratio of transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.DV Power turns ratio testers can output various test voltages for different applications. From the extremely low test voltage of 1 V AC that enables turns ratio verification of the majority of current transformers, up to the highest test voltage of 500 V AC that provides the most accurate turns ratio testing of power transformers used in power generation and transmission. By using the external booster, test voltage increases up to 5 kV AC in order to successfully test capacitive voltage transformers.All DV Power turns ratio testers have a built-in tap changer control unit. Because of that, it is possible to control the on-load tap changer (OLTC) directly from the device. In order to make the most out of this feature, the instrument and included DV-Win software can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions, and saving results. This option significantly facilitates and shortens the turns ratio testing time.TRT turns ratio testers use the same set of cables as three-phase winding ohmmeter & tap changer analyzers from the TWA series. Consequently, it enables one-time cable setup for performing eight tests:turns ratioexcitation currentphase anglemagnetic balancevector group detectionwinding resistanceon-load tap changer DVtestand demagnetization.

Making a product “safe” requires an understanding of “hazards” that exist in each electrical product. Electrical shock is one of the four fundamental hazards. Because of that, it must be a part of any product electrical safety evaluation. Even though a product requires an electrical power source and uses electrical or electronic components, it should not present an electrical shock hazard to the user.Ground bond or earth continuity testing prevents electrical shock hazards. Similarly to a fault to earth, test instruments generate a high current. The standard requires that the resistance between protective earth and any conductive surface on the equipment does not exceed 0,1 Ohm. The test is performed by applying a DC current between the conductive surface and protective earth. By measuring the voltage drop, it calculates the resistance.RMO-E instruments are ideal for testing the protective bonding (grounding) of equipment following the standard IEC 61010-1. Applying current up to the value of 100 A and the ability to provide in the Contin menu (continuous operation) test current for the pre-set test duration (equal or exceeding 1 min) gives a user a possibility to easily check the protective bonding/grounding of the equipment. The full load voltage of 12 V assures proper measurement and accurate result. Finally, an instrument displays pass/fail classification according to user-preset parameters.

Over 135 different sensors are available in a variety of packages to fit any environment, from indoor clean rooms to harsh locations outdoors to 100 meters under water. Please note that Solar Light offers both Digital Sensors and Analog Sensors in the PMA-Series lineup. Select these Analog Sensors if you don’t need a digital display output of the reading, if you will be connecting to your own datalogger, or if you plan to use a voltage source to provide excitation voltage to the sensor and a digital volt or amp meter to read and convert the results. Analog Sensors are typically used as process sensors that are permanently installed to provide ongoing information. Typical current draw is under 1mA. (By contrast, Digital models are typically used as discrete sensors that are portable and located to provide short term information.)
