Types of Electrical Transformers
Types of Electrical Transformers Besides varying in size, transformers can be categorized into different types to meet energy needs. Voltage Transformers Voltage transformers can also be called “potential transformers.” They step down a large voltage and operate in parallel with the i...Read More -
How do power transformers work?
How do power transformers work? Power transformers operate based on Faraday’s law. Simply put, they use electromagnetic induction to connect two circuits, transferring current from one circuit to the other. As mentioned earlier, the voltage may sometimes increase or decrease during the tran...Read More -

Correct use of high-voltage switchgear grounding switch
The grounding switch in high-voltage switchgear is a mechanical grounding device used for safety maintenance. During electrical equipment maintenance, it grounds potentially energized circuit breakers or busbars to prevent induced voltage from harming maintenance personnel. The typical operation ...Read More -
High-voltage electrical testing and testing equipment
High-voltage electrical testing equipment is a specialized tool used to inspect, measure, and diagnose the performance and safety status of high-voltage electrical equipment (such as power transformers, circuit breakers, cables, and lightning arresters). The following are common categories and ty...Read More -
The main function of a transformer
The main function of a transformer is to step up and down the voltage, changing the AC voltage without changing the frequency of the AC power through the principle of electromagnetic induction. It also converts current, provides electrical isolation, protects circuits, and performs impedance matc...Read More -
