  • How to judge transformer fault casting by transformer oil

    Common faults that can easily occur in transformers can be divided into two categories: common faults for charging and common faults for heat. From the development process

  • Transformer DC resistance tester maintenance skills

    According to the division of labor of the management personnel in Taiwan, in addition to regular transformer work.

  • What Is a Voltage Withstand Test and Why Is It Critical for Electrical Safety

    A Voltage Withstand Test, often referred to as a dielectric strength test or hi-pot test, is a fundamental procedure used to verify the electrical insulation integrity of equipment, components, and systems. This comprehensive guide explains what a voltage withstand test is, how it works, why it is essential for electrical safety, and how manufacturers such as Weshine apply it to meet global compliance standards. The article also covers test procedures, standards, common failures, comparison with related tests, and best practices, helping engineers, quality managers, and procurement professionals make informed decisions.

  • What Is a Partial Discharge Test and Why Is It Essential for Electrical Asset Integrity

    Partial Discharge Test plays a pivotal role in high-voltage insulation diagnostics and predictive maintenance. In this comprehensive article, we explore what partial discharge (PD) is, how PD testing equipment works, and why high-quality testing systems — such as the Weshine Partial Discharge Test solutions — are essential in preventing costly electrical failures.

  • What Are the Latest Technologies in Portable Gas Analyzers

    As a professional working in environmental monitoring and industrial safety, I often hear one pressing question from my peers and clients what are the latest technologies in portable gas analyzers that can address our real-world challenges. Rapid, accurate, and reliable Gas Analysis is no longer a luxury—it’s a critical necessity. At the heart of this evolution is our commitment at Weshine to integrate cutting-edge innovations that directly solve field operation pain points. Let’s delve into the advancements that are redefining portable Gas Analysis.

  • What is High Potential Ability Test (HIPOT)?

    Voltage withstand test is the abbreviation for high potential (high voltage) test, also known as insulation voltage withstand test. Hipot testing checks for 'good isolation'. The Hilbert test ensures that no current flows from one point to another. The Hilbert test is the opposite of the continuity test. The continuity test checks whether the current easily flows from one point to another, while the Hipot test checks the guarantee that the current will not flow from one point to another (and adjusts the voltage very high to ensure that no current flows)
