What causes thermal failures in the core of an oil-immersed transformer? Today we’ll discuss some types of thermal failures in oil-immersed transformers, specifically core failures. Core failures account for about 3% of all overheating failures, a proportion that warrants our attention. So,...Read More -
Transformer Protection System
Transformer Protection System Now we will explain the components and systems of the protection section. First, we need to classify the emergency protection system: Classification: (1) Power Disconnection Device: Disconnects the faulty transformer from the power grid. (2) Pressure Relief Device: D...Read More -

How to select a transformer based on its no-load current and no-load loss? In the previous section, we explained the characteristics and meanings of no-load current and no-load loss to provide a reference for reasonable selection. Regarding parameter selection, each manufacturer will provide a de...Read More -
Transformer Load Loss
Transformer Load Loss: An Introduction from a Transformer Selection Perspective Transformer load loss is a crucial parameter among transformer parameters. To help users better understand this parameter, we will introduce it today, covering its meaning and characteristics, along with some simple e...Read More -
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-p...
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 -
