How is the insulation level of a transformer assessed and...
How is the insulation level of a transformer assessed and defined? Today, we will explain how to judge the insulation level of a transformer. This is because the insulation level is a standard for assessing transformer quality, and as a transformer manufacturer, we feel it’s necessary to ex...Read More -

What causes thermal failures in the core of an oil-immersed transformer? Previously, based on statistical data, our manufacturer analyzed the principles and formation processes of common transformer fault types. Yesterday, we also provided some examples to reinforce the concepts and provide a mor...Read More -

What are the differences between three-phase and single-phase transformers? Today, we will mainly compare three-phase and single-phase transformers. Firstly, single-phase transformers were invented first, and three-phase transformers were developed later. This is basic historical knowledge that o...Read More -
Disconnecting Switch
Disconnecting Switch A disconnecting switch (or disconnector) is a switching device that, when in the open position, has a specified insulation distance between its contacts and a clear disconnection mark; when in the closed position, it can carry current under normal circuit conditions and curre...Read More -
Single-phase transformers: a new energy-saving system for...
Single-phase transformers: a new energy-saving system for urban lighting Three-phase systems are commonly used in my country’s low-voltage power distribution systems. Currently, the power supply method in low-voltage distribution networks is characterized by “small capacity, dense dis...Read More -
Common Electrical Knowledge in Daily Life
Three-phase alternating current is a combination of three alternating currents, with the same frequency, but the phases are offset by 120 degrees. The voltage between the live wire and the neutral wire is called the phase voltage (between the live wire and the neutral wire). The voltage between t...Read More -
Amorphous Solid Core For Transformer
Amorphous Solid Core For thousands of years, the metals and alloys used by humankind have been materials with crystalline structures, in which atoms are arranged in a three-dimensional, ordered manner, forming a periodic crystal lattice structure. When amorphous alloys are rapidly cooled from a l...Read More -
Silicon steel core for dry-type transformers
Silicon steel core for dry-type transformers Silicon steel sheets are an indispensable soft magnetic alloy in the power, electronics, and military industries, and are also the most widely used functional metallic material, primarily used as the core of various motors, generators, and transformers...Read More -

Silicon steel sheets are an indispensable soft magnetic alloy in the power, electronics, and military industries, and are also the most widely used functional metallic material, primarily used as the cores of various motors, genera...Read More -
How to Diagnose Faults in Dry-Type Transformers by Sound
How to Diagnose Faults in Dry-Type Transformers by Sound Dry-type transformers typically operate without any noise, which is normal. However, some processes may produce significant noise, indicating that the sound can help identify potential faults. In fact, the sound of a dry-type transformer ca...Read More -
Reasons for Overheating of Dry-Type Transformer Cores
Reasons for Overheating of Dry-Type Transformer Cores When a dry-type transformer is working, the magnetic field of the current in the electromagnetic coil causes the magnetic flux to change alternately. This changing magnetic flux induces an electromotive force (EMF) in the core. This induced EM...Read More -
Handling Fires in Dry-Type Transformers
Handling Fires in Dry-Type Transformers 1. Fires Caused by Insulation Aging (Fire faults in dry-type transformers are relatively common during operation) Statistical analysis shows that 50% of burnt dry-type transformers are caused by insulation aging leading to breakdown. During operation, dry-t...Read More
