Introduction DBBR-IV Active transformer features - Capacity Tester is I plant specially developed for this problem, developed specifically for transformer capacity, loss parameter measurements of high precision instruments. It comes with high-performance rechargeable battery, no external power supply to work, charging time can be continuously measured 100 times; at the same time, internal standard three-phase sine wave signal digital synthesis (by no means simple inverter AC output, to ensure that the non-rated conditions The accuracy of each test item under test data), the amplifier can provide accurate three-phase AC test source; no external power supply and three-phase test regulator in short circuit loss measurement transformers and transformer capacity, up-flow and other auxiliary equipment simplify the wiring, greatly improving the work efficiency; capacity test results 100% accuracy. It is a device that is equivalent to two kinds of devices: an active transformer capacity tester + transformer loss parameter tester. It can be for a variety of transformer capacity, load current, load loss, short-circuit loss, impedance voltage and a series of frequency parameters can be precisely measured. The instrument has a small size, light weight, measurement accuracy, good stability, easy to learn and easy to operate, etc., completely replace the use of multi-table method measuring transformer losses and capacity ever, wiring, easy test, record, greatly improving work efficiency. It to the big screen as a graphical LCD display window, graphical menu operation and with a character prompt, set multiple parameters in one screen display interface, interactive user-friendly, easy to use, fast, is the product of choice for power users at all levels . Product Features? Can accurately measure capacity, passive measurement of various distribution transformers, convenient and accurate. ? Measure various types of transformer no-load current, load loss, short-circuit voltage, short-circuit loss, zero sequence impedance. ? Automatic waveform distortion correction, temperature correction, voltage correction (non-load test at rated voltage), the current correction (non-rated short-circuit test current condition), the operator simply based on the type of input transformer can be corrected index instrument automatically calculate the corrected results, it did not do much for a slightly larger unit transformer short-circuit test conditions. ? Allow external voltage transformer and current transformer extended range measure, measure any parameter of the test product. ? Wide voltage circuit quantity is limited: maximum measurable voltage to 750V, without switching gear to ensure accuracy. The voltage level will not be wrong and damage to the instrument itself. ? Large screen, high brightness LCD display, full Chinese menu and operation tips to achieve a friendly man-machine dialogue, touch buttons make operation easier, wide LCD with brightness adjustment, can be adapted to winter and summer seasons. ? Users can keep the test data via a mini printer will print out the results. Technical Specifications 1.
