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.

There is nothing worse than running your drops only to learn that you have a fault in one of the cable runs. Get it right the first time, get it right by choosing and using the right LAN Cable Testers. We offer a variety of cable testers, which are a must have to quickly and easily verify the integrity of Ethernet twisted pair cables. Our LAN testers will test twisted pair cables for open pairs, shorted pairs, reversed pairs, crossed pairs and split pairs. Network cable testers vary in complexity and price, but a basic tester consists of a source of electrical current and a measuring device. After that, cable testers vary in complexity and ability to do various testing.

DEM60C -
IBEKO Power AB
After a DC current test, such as winding resistance measurement, the magnetic core of a power or instrument transformer may be magnetized (remnant magnetism). It can cause various problems such as wrong diagnostics, inaccurate measurements on a transformer, inrush current at the start-up of a power transformer, or incorrect operation of protective relays due to magnetized CT cores. The best way to eliminate this source of potential problems is to use demagnetizer on the power or instrument transformer.The DEM60C is a fully automatic test instrument which performs three-phase transformer demagnetization. Transformer magnetic core demagnetization requires the application of AC current with magnitude decreasing to zero. DEM60C provides this AC current by internally changing the polarity of a controlled DC current. During the demagnetization process, the instrument supplies the current at decreasing magnitude for each step, following a proprietary algorithm. It can demagnetize single-phase and three-phase power transformers.The instrument can be connected to all three phases of a power transformer to be demagnetized, on either the primary or the secondary side. If a user selects specific vector diagrams for different types of transformers, DEM60C will run a specific demagnetization procedure for each transformer type (i.e., single phase, delta, wye/star, zig-zag.) without switching the test leads.DEM60C enables safe and efficient power transformer demagnetization. The instrument automatically regulates the injection of current and discharging energy from the inductance. During and after the operation, an intrinsically safe discharge circuit with an indicator rapidly dissipates the stored magnetic energy. The discharging circuit is independent of the power supply, which improves its reliability in case of loss of power.Test currents of up to 60 A DC enable efficient demagnetization of even the largest power transformers. Using a DV Win software, it is possible to control DEM60C externally.
