Transformers are used for voltage conversion on power system lines. The purpose of the transformer converting voltage and electric energy is to transfer electric energy, which is different from the transformer converting voltage. It mainly provides electric energy for relay protection devices and measuring instruments. The voltage, energy and power of the line were measured. Transformers also play a role in protecting the line and valuable equipment, motors and transformers when a line fault occurs. Therefore, the role of the transformer is also very important
The need of current transformer tester becomes understandable to everyone when one considers the reality that current transformer failure can cause catastrophic damage. A fault causing an open circuit in the secondary can cause the primary current to exceed the insulation, causing the winding to short-circuit. With Push,China’s range of current transformer test equipment, you can develop in-depth testing and maintenance plans to prevent problems before they occur.
CT PT test
A series of routine diagnostics and tests for current transformers should include CT saturation testing to determine the knee point according to IEEE or IEC standards; CT ratio testing to determine that the voltage ratio is within expected parameters; current transformer winding resistance testing and CT insulation Resistance test.
Current transformers are saturation tested according to IEEE or IEC standards by a ct pt tester to determine the rated knee point, the point at which the transformer can no longer deliver current at the specified rate.
Ratio testing under normal load is accomplished by comparing the voltage applied to the secondary winding with the voltage developed on the primary winding. Current transformer resistance testing injects a test voltage to measure DC current and calculates the resistance value, taking into account temperature.
The ct pt tester uses high-performance DSP and ARM, advanced manufacturing technology, stable and reliable product performance, complete functions, high degree of automation, and high testing efficiency, which is at the leading level in the country. It is a professional testing instrument for transformers in the power industry.
Frequency Conversion Transformer Test
The function of the Frequency Conversion Transformer Tester (also known as the inductor volt-ampere characteristic tester) is mainly for inductors with small capacity, generally only a few volts to dozens of volts, generally no more than kilovolts. Its working principle, wiring method and ferromagnetic Resonance and other characteristics, carry out research and development design.
The functions of the Frequency Conversion Transformer Tester mainly include: testing the volt-ampere characteristics of the CT, error curves of 5%, 10% and 15%, transformation ratio, polarity and other parameters. In addition, it can also detect the secondary direct resistance, secondary load and secondary loop data of the transformer, as well as the demagnetization function of the transformer. From this we can know that the functions of the comprehensive instrument transformer tester are very comprehensive and powerful. Therefore, the Frequency Conversion Transformer Tester is not only powerful in function, but also easy to operate, which greatly improves the work efficiency of power workers!
Easy-to-operate current transformer tester from China
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, Push,China’s current transformer tester only need conductors to detect these functions of the transformer we produce. The operation of the Frequency Conversion Transformer Tester is also very simple. The ct pt tester eliminates traditional manual recording, manual pressure adjustment, manual sorting, curve description and other tasks.
The ct pt tester only needs to simply set the number of the test voltage, and the instrument can automatically increase the voltage step by step from zero. During the entire test process, the ct pt tester automatically records data and automatically draws the volt-ampere characteristic curve on the screen. The curve data can be transmitted to the computer.
