  • 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.

  • Common faults of High-voltage Test Transformers(AC Hipot Tester)

    High voltage test transformers can also experience faults in normal use, but small faults such as short circuits can actually be avoided. Now, let's introduce in detail the common faults and solutions of high-voltage test transformers.

  • Multiple methods for troubleshooting power equipment faults

    In daily use, power equipment is sometimes prone to malfunctions, so analyzing the phenomenon and promptly identifying the cause of the malfunction is the key to identifying power faults. The basic theory of electricians is the foundation of analysis, which combines a full understanding of the structure, principle, and performance of power devices with practical faults.

  • 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.

  • Multiple measurements of power quality

    ​Weshine's independently developed power quality analyzer is a portable product that detects and analyzes the operational quality of the power grid. It can provide harmonic analysis and power quality analysis in power operation, and is equipped with large capacity memory for long-term data collection and detection of power grid operation. At the same time, it is equipped with PC application software to upload the collected data to the computer for various analyses.

  • What types of hipot tests are there?

    Hipot Test, or withstand voltage test, can be mainly divided into the following two types according to its characteristics and applications:
