  • How to ensure the transportation of DC resistance testers?

    The transformer DC resistance tester is commonly used to measure the DC resistance of large capacity transformers. It is a high-precision stable current power supply and testing part designed as a whole. The testing process is controlled by a microcomputer and automatically completes stable current judgment, data acquisition, data processing, resistance value display and printing. This instrument can complete the longitudinal test of the on load voltage regulator with one power supply, fully saving test time.

  • Development status and trends of integrated substation automation

    The substation is an indispensable and important link in the power system. It is responsible for the heavy tasks of power conversion and power redistribution, and plays a decisive role in the economic operation of the power grid. In order to improve the stable operation level of substations, reduce operation and maintenance costs, improve economic benefits, and provide high-quality electric energy services to users, comprehensive automation technology for substations has begun to emerge and has been widely used.

  • Explanation of the functional characteristics of the transformer DC resistance tester

    ​The transformer DC resistance tester is based on a high-speed microcontroller, using high-speed A/D converters and programmable current source technology to achieve measurement results and highly automated measurement functions. It has high accuracy, wide measurement range, stable data, good repeatability, strong anti-interference ability, and complete protection functions. The characteristics of fast charging and discharging speed. This instrument. Small in size, light in weight, and easy to carry, it is a new generation product for transformer DC resistance testing.

  • Common technical issues during transformer tester testing

    ​In fact, the accuracy of transformer testers is not an important indicator of the instrument. In the transformer calibration regulations, it is required that the testing error caused by the entire circuit should not exceed 20% of the level of the tested transformer, and the presented data must be true. The common technical issues during the testing process are as follows:

  • What are the operating techniques for Cable Fault Locator?

    ​1. After the cable fault tester has connected the lines on site according to the multiple pulse method, it is normal if a more ideal test waveform cannot be obtained by applying high impact voltage at one time. Because the distance to the fault is not known in advance, the electrical strength of the fault point is also unclear. If the impulse voltage is not high enough and the fault point is not broken down by the impulse high voltage to generate an arc, the fault echo cannot be collected. At this time, only the terminal open circuit waveform can be seen. The impulse voltage must be increased until fault echoes are seen.

  • The connection between transformer tester and power efficiency

    ​The ratio of the output signal power of a transformer tester to the input processing power during additional task power is called the power of a transformer parameter tester. The transformer tester may not cause any loss, but in practice, this type of transformer tester is not available. The magnetic flux of the transformer tester's iron core is related to the applied voltage.
