What function does Automatic CT PT Analyzer have ?
Voltage transformers are similar to transformers. The transformation of voltage on the power system lines requires the use of transformers. The purpose of transformer voltage conversion is to transmit electrical energy. Unlike transformers, transformers convert voltages. They are mainly used to supply relay protection devices and measuring instruments. The voltage, power and power of the lines have been measured. It functions as a protection line when a line fault occurs. Therefore, the role of transformers is also very important. For the detection of transformers, electric power workers need to use a comprehensive transformer tester, so what are the specific functions of a comprehensive transformer tester?
The function of the transformer comprehensive tester is mainly for the small capacity of the transformer. It usually only needs a few volts to tens of volts, and generally does not exceed thousand volts, and its working principle, wiring mode, and ferromagnetic resonance. Designed for R & D. The functions of the comprehensive transformer tester mainly include: testing the volt-ampere characteristics of CT, detecting the error curves of 5%, 10%, and 15%, and also detecting the transformation ratio and polarity of the transformer In addition, it can also detect the secondary direct resistance, secondary load and secondary circuit of the transformer, as well as the demagnetization function of the transformer. From this we can know that the function of the transformer integrated tester is very comprehensive and powerful.
So are the specific steps to achieve these functions very complicated?
The traditional detection method has a lot of wiring, and many components are very complicated to connect. However, according to the development of the times and science and technology, these functions of detecting transformers can be completed by only a comprehensive transformer tester. The operation of the instrument is also very simple. The instrument eliminates the traditional manual recording, manual pressure adjustment, manual finishing, and curve drawing. It only needs to perform simple digital setting of the highest test voltage on the instrument, and the instrument can automatically change from zero The voltage is increased step by step. During the entire test process, the instrument automatically records the data and automatically displays the volt-ampere characteristic curve on the screen. The curve data can be transmitted to the computer.
Therefore, the comprehensive transformer tester is not only powerful, but also easy to operate, which greatly improves the work efficiency of power workers! welcome inquiry for more information!
