In addition to charging the cost measured by the metering device, we also need to collect the basic electricity charge according to the transformer capacity. For larger users in the operation of Transformers, but also a one-time increase in capacity fees. With the development of the power industry and the increase in power consumption, self-owned Transformers and individual contracted Transformers have gradually occupied a considerable share of the blending. What follows is all kinds of fraudulent means adopted by individuals in order to achieve the goal of paying less and using more electricity(mainly changing and changing Transformer nameplates); Some users steal electricity as much as hundreds of thousands of dollars a year, and the power department suffers from no effective control.

Active Transformer character-capacity synthesizer is a high precision instrument specially developed and developed by our company to measure Transformer capacity and loss parameters. It is equipped with a high-performance rechargeable battery, which can work without external power supply, and can measure 500 consecutive times at a time. At the same time, internal digital synthesis of three-phase standard sine wave signals(by no means a simple inverse AC output, ensuring the accuracy of test data for each test item under non-rated conditions), power amplifiers can provide three-phase precision AC test sources; When measuring Transformer capacity and transformer short-circuit loss, auxiliary equipment such as three-phase test power supply and regulator, hoist, etc. are not required to be connected to simplify the wiring and greatly improve the working efficiency.

The accuracy of the capacity test results reached 100 %. One kind of equipment is equivalent to four kinds of equipment: active Transformer capacity tester + Transformer loss parameter tester + harmonic analyzer + oscilloscope. It can accurately measure a series of power frequency parameters such as capacity, empty load current, empty load loss, short circuit loss, impedance voltage, etc. of various Transformers, and can measure the voltage and electric loss true harmony wave content during the empty load test. Can also perform vector analysis.

The instrument has the advantages of small size, light weight, high measurement accuracy, good stability, and simple and easy to learn. It can completely replace the previous method of measuring Transformer loss and capacity using multi-meter method, and has simple wiring, convenient testing and recording. It has greatly improved the efficiency of the work. It uses a large-screen color liquid crystal as a display window. The menu is operated and equipped with Chinese character hints. The display interface with multiple parameters on one screen is a friendly human-machine dialogue interface. It is easy to use and fast to use. It is the preferred product for power users at all levels.
