The area of the window and the cross-sectional area of the bracket are the main dimensions of the transformer, whose product is proportional to its size and weight.In general, the larger the product, the larger and heavier the transformer will be.
The magnetostrictive effect is one of the main causes of transformer noise. When a magnetic field is applied to ferromagnetic materials, their size changes. Power transformers have iron cores that are magnetically attracted to alternating current flowing through their coils. Creating a buzzing sound, it expands and contracts the core.
An inductor is an essential component of any circuit. To make a circuit work, it supplies the necessary voltage. It is necessary for the generation of current and the operation of power sources. Inductor structure is similar to that of a transformer, but with only one winding. The inductance of an inductor is determined by its resistance to current flow changes only.
Transformer oil and components will change in color and smell if there is a fault inside the transformer or if it is overheated. The following are some common faults:
1. A loose casing terminal or a slippery lead wire nose can seriously oxidize the contact surface, overheat the contact, cause the color to darken, tarnish, and damage the surface coating.

Transformers are static electrical devices.An electromagnetic induction device converts a certain level of AC voltage and current into another level of voltage and current at the same frequency. Transforming AC voltage, exchanging AC current, and transforming impedance is its main function. Leakage current is the tiny induced current generated around the insulating material by the electric field force, and it is commonly expressed in microamps.
Current transformer measurement or protection system can convert a high voltage into a low voltage and a large current into a small current. Basically, it is used to convert high voltage or high current into standard low voltage (100V) or standard low current (5A or 1A, all in proportion to the rated value) in order to standardize and reduce the size of measuring instruments, protection equipment, and automatic control devices.
For voltage transformation, transformers use the electromagnetic principle of “electricity generates magnetism, and magnetism generates electricity.”
Power transformers are electromagnetic components that transmit power, convert voltage, and isolate insulation, and are widely used in power supply and power electronics applications. Power transformers can be divided into several stages based on the size of the transmission power.
Inductors and transformers are electromagnetic induction components that are wound with insulated wires and are also commonly used in electronic circuits. In spite of the fact that they look similar, they actually function differently.
