Zhejiang Zuoao Technology Co., Ltd is a professional manufacturer of intelligent controller (PCBA) and power transformer products. Our toroidal single phase power transformer includes toroidal medical power transformers, household toroidal single-phase transformer, Lift & Elevator used toroidal transformer, toroidal transformer for audio, toroidal transformer for UPS, etc. A transformer is a very important electrical device, mainly used to help transmit current and voltage between different circuits.
A toroidal single phase power transformer operates on single-phase power and has two parts - the magnetic and the electric parts. The magnetic transformer part consists of a magnetic iron core, while the electric part consists of a copper transformer. A transformer doesn't have any moving parts; hence, there is no mechanical friction when operating a single-phase transformer. Therefore, there are few energy losses when using a single-phase transformer, making the single-phase transformer highly efficient.
Benefits of Toroidal Single Phase Power Transformer
Use less material
Single-phase transformers with the same capacity use 20% less iron than three-phase transformers. Especially when the wound core structure is adopted, the no-load loss of the transformer can be reduced by more than 15%, which will reduce the manufacturing cost and use cost of the single-phase transformer at the same time, so as to obtain the best life cycle cost.
Low line investment
Using a single-phase power supply system in the power grid can save 33% to 63% of wires. Calculated according to economic current density, it can save 42% of wire weight. Calculated according to mechanical strength, it can reduce wire consumption by 66%. Therefore, the construction investment of the entire transmission line can be reduced. This is very meaningful in terms of street lighting and residential electricity consumption in vast rural areas and towns.
Conducive to modern production
Due to its simple structure, single-phase transformers are suitable for large-scale modern production, which is conducive to improving product quality and efficiency.
Low installation requirements
The single-phase transformer is light in weight and can be flexibly installed on the pole for use. It is convenient to go deep into the load center, step down the power supply nearby, and improve the quality of power supply.
High security
Generally, single-phase transformers supply power in a small area, and the affected area of faults is small, which is conducive to improving the reliability of power supply.
Flexible use
Because single-phase transformers are light in weight and easy to install and maintain, they can be used in single-phase or three-phase transformers.
Inductance of a Toroidal Single Phase Power Transformer
Show that the inductance of a toroid of rectangular cross-section is given by:

Where (N) is the total number of turns, (a) is the inner radius, (b) is the outside radius and (H) is the height of the toroid.
Construction Of Toroidal Single Phase Power Transformer
A single phase transformer is a high-efficiency piece of electrical equipment, and its losses are very low because there isn't any mechanical friction involved in its operation. Transformers are used in almost all electrical systems from low voltage up to the highest voltage level. It operates only with alternating current (AC) because direct current (DC) does not create any electromagnetic induction. The key components of a toroidal single phase power transformer are:
Core
It is made up of grain-oriented silicon steel laminations to reduce eddy current losses. The core provides a low reluctance path for the magnetic flux.
Primary Winding
It is connected to the source of alternating supply. The number of turns in the primary winding is kept as minimum as possible to reduce copper losses.
Secondary Winding
It is connected to the load. The number of turns is adjusted to get the required output voltage value from the induced EMF.
