Product introduction:
Short circuit impedance is an important parameter of transformer, and the method of short circuit impedance is the traditional method to judge the winding deformation. According to the provisions of gb1094.5-2003 and iec60076-5:2000, the change of short-circuit reactance is the only criterion to judge whether the transformer winding has deformation. This instrument circuit design is exquisite, the thought is unique, the performance is superior, the volume is small, the weight is light, the spot use is convenient. The instrument adopts advanced double A/D synchronous ac sampling and digital signal processing technology, the measurement data is accurate and reliable, and it is an effective tool for transformer detection and analysis.
Functional description:
1. Can measure transformer short circuit impedance, short circuit reactance, short circuit resistance, three phase impedance voltage.
2. Can display the voltage, current, power, frequency and other parameters of each test.
Only 220V single-phase ac power supply can be used to complete the measurement. In the absence of ac power supply, low-power UPS can be used
3. Source power supply (online 500VA).
4. Wiring operation is simple and convenient, one wiring, one start can automatically complete the three-phase measurement, directly display the measurement results.
5. Internal automatic control of output voltage and output current, without any external auxiliary equipment.
6. Automatic frequency correction can eliminate the error caused by frequency fluctuation.
7. It can store the results of 90 times of measurement. The instrument has no built-in electric memory, which can store the measurement data for a long time.
8. Large blue screen LCD display, all Chinese menu and operation tips, intuitive and convenient.
9. No power off calendar, clock function.
