  • What is the open circuit voltage test?

    ​A measurement method called the open circuit voltage test is used to find the voltage that a transformer produces across its terminals when there is no load on it. There is no electricity flowing through the transformer during this test since the secondary winding is left open. Next, a voltage source equal to the transformer's rated voltage energizes the primary winding.

  • 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.

  • Evaluation of the voltage withstand capability of electrical equipment insulation.

    ​A technical means to test and evaluate the insulation withstand voltage capability of electrical equipment. Insulation structures need to be used to isolate the live parts of all electrical equipment from the grounded parts, or from other non-equipotential live bodies, to ensure the normal operation of the equipment.

  • How should insulation and voltage withstand testers be used correctly?

    The quality of products is now an issue that every manufacturer cannot ignore. Assuming that the work is not done well, it will affect the company's reputation and lead to customer distrust. Therefore, regulatory requirements have become one of the important technical specifications. The various elements of the quality application of insulation and withstand voltage testers are very important.

  • Maintenance power of transformer tester

    ​The magnetic flux of the transformer tester's iron core is related to the applied voltage. Transformer testers should be kept away from strong electric fields, magnetic fields, and high-frequency equipment. The smaller the interference of the power supply, the better. It is advisable to choose lighting lines. Assuming that the power interference is still significant, the instrument can be powered by a communication purification power supply with a capacity greater than 200VA.

  • Why Is an AC Hipot Test Kit Essential for Electrical Safety and High-Voltage Equipment Testing

    High-voltage electrical systems require reliable insulation performance to ensure operational safety, equipment longevity, and regulatory compliance. An AC Hipot Test Kit is one of the most important tools used in the power industry to verify insulation integrity and detect potential failures before they lead to dangerous accidents or costly downtime.
