This article will focus on the CT and VT testing procedure, and will also describe some specific operational details.

Although the DC withstand voltage test and leakage current measurement methods are the same, their functions are different. The former is to test the insulation's dielectric strength, and its test voltage is higher; the latter is used to check the insulation condition, and the test voltage is relatively low.

Concise guide to series resonance testing: common faults, causes, and practical fixes for resonance points, main unit resets, Q-value issues, and power trips.

Explore the importance of dielectric strength and oil chromatography in electrical systems. Learn their applications, testing methods, and benefits for system reliability and performance.

Explore generator rotor and stator principles, and learn how rotor winding short-circuit issues are detected and predicted for reliable operation.

Learn the role and purpose of lightning arresters, how they differ from surge protectors, their working principles, and tips for choosing lightning test equipment.

The article will focus on other necessary tests about transformer, such as AC withstand Voltage Test, Insulation dielectric performance test, Winding DC resistance measurement, CVT and so on.

This article will describe the necessary tests for transformers, focusing on insulation resistance measurement, dielectric loss factor and capacitance measurement, and partial discharge testing.

This article mainly introduces the relevant regulations for equipment grounding, grounding system and grounding impedance measurement.

This article will focus on the correlation and differences between VLF testing, TD testing and PD testing, and at the same time, you can find out which testing method is more suitable for your needs.
