Analysis of the use of frequency conversion transformer tester

The voltage conversion on the power system line needs to be used in the transformer. The purpose of the transformer to convert voltage and electric energy is to transfer electric energy, which is different from the transformer to convert voltage, which mainly provides electric energy for relay protection devices and measuring instruments. The voltage, electric energy and power of the line are measured. When the line fails, the transformer also plays a role in protecting the line and valuable equipment, motors and transformers. Therefore, the role of the transformer is also very important. For the detection of the transformer, the power staff needs to use a transformer comprehensive tester, so what are the specific functions of the transformer comprehensive tester?

The function of the transformer comprehensive tester (also known as the inductor volt-ampere characteristic tester) is mainly aimed at the small capacity of the inductor, which generally only requires a few volts to tens of volts, generally not more than kilovolts, and its working principle, wiring method, and ferromagnetic resonance and other characteristics, and is developed and designed. The functions of the transformer comprehensive tester mainly include: testing the volt-ampere characteristics of the CT, 5%, 10% and 15% error curves, ratio, polarity and other parameters. In addition, the secondary direct resistance, secondary load and secondary circuit of the transformer can also be detected, as well as the demagnetization function of the transformer. From this we can know that the functions of the transformer comprehensive tester are very comprehensive and powerful. Therefore, the transformer comprehensive tester is not only powerful, but also easy to operate, which greatly improves the work efficiency of power workers!

Are the specific steps to achieve these functions very complicated? The traditional detection method has many wirings and many components to connect, which is very complicated. However, with the development of the times and science and technology, only a transformer comprehensive tester is needed to detect these functions of the transformer. The operation of the instrument is also very simple. The instrument eliminates the traditional manual recording, manual voltage adjustment, manual sorting, curve description and other work. The instrument only needs to simply set the test voltage number, and the instrument can automatically step up from zero. During the entire test process, the instrument automatically records data and automatically draws the volt-ampere characteristic curve on the screen, and the curve data can be transmitted to the computer.
