Voltage transformer is similar to transformer, the transformation of voltage on power system line needs to use transformer. The purpose of transformer transformation voltage is to transmit electric energy. Unlike transformer, transformer transformation voltage is mainly used to supply power for relay protection device and measuring instrument. The voltage, electric energy and power of the line have been measured. The transformer also functions as a protection line, valuable equipment, motor and transformer in case of line fault. Therefore, the role of transformer is also very important. For the detection of transformer, power workers need to use the transformer comprehensive tester, so what is the specific function of the transformer comprehensive tester?
The function of the instrument is mainly aimed at the small capacity of the instrument transformer, which usually only needs a few to dozens of VA, generally no more than KVA, as well as its working principle, wiring mode, ferromagnetic resonance and other characteristics. The functions of the instrument transformer comprehensive tester mainly include: testing the volt ampere characteristics of CT, testing the error curves of 5%, 10% and 15%, and testing the transformation ratio, polarity and other parameters of the instrument transformer. In addition, it can also detect the secondary direct resistance, secondary load, secondary circuit and other data of the instrument transformer, as well as the demagnetization function of the instrument transformer. From this we can know that the function of transformer comprehensive tester is very comprehensive and powerful.
Are the steps to implement these functions very complicated? The traditional detection method has many wiring, many parts to connect, is very complex. However, according to the development of the times and science and technology, these functions of the detection transformer can be completed only by a comprehensive tester. The operation of the instrument is also very simple. The traditional manual recording, manual voltage regulation, manual sorting, curve tracing and other work are omitted. Only a simple digital setting of the highest test voltage is required for the instrument, and the instrument can automatically step up from zero to one. The instrument automatically records the data during the whole test process, and automatically describes and displays the volt ampere characteristic curve. On the screen, and the curve data can be transmitted with the computer.
Therefore, the transformer comprehensive tester is not only powerful, but also easy to operate, which greatly improves the work efficiency of power workers!
