An isolation transformer is a narrow-profile professional equipment that is used to distribute the incoming load of electrical circuits. It also carries out the process of converting electricity and provides a high level of protection against electrical injuries.
The basic principle of a standard isolation transformer does not differ at all from any other voltage-normalizing similar devices. The transformer continuously converts the incoming flow of electricity. On the main magnetic circuit of this device, two standard windings of an insulated wire with the same characteristics are installed. The power of the sinusoidal harmonic electricity first passes through the primary winding, after which, according to the principle of electromagnetic induction, it is continuously converted in the secondary winding.
Application of a standard isolation transformer
A single-phase isolation transformer is used to increase the safety level of continuously functioning high-power electrical devices, and, consequently, to reduce the level of electrical injuries. The primary condition for the use of standard models of an isolation transformer is the use of autonomous power windings for various sections of the voltage circuits of devices powered from a common power supply circuit. Isolation transformers are installed everywhere today, since it is the most efficient and affordable device that works without interruptions, has a low noise level, is compact and easy to install and easy to maintain.
Electricity consumption
The isolation transformer, like any other electrical device, loses a small part of the incoming electricity during operation. The operating losses of the isolation transformer are assessed by the efficiency level of each device individually. In various models of isolation transformers, the efficiency may slightly fluctuate within the range of 75-85%. So we can conclude that there will be no significant, visible savings in electricity passing through the transformer. In the case of isolation transformer operation, it is almost always neglected for the sake of a high level of safety.
Isolation transformers are now used in such specific areas as the power supply of highly specialized professional medical stationary and portable stations, in large industrial plants, in schools and kindergartens. In hospitals in most developed countries, isolation transformers have long been used as the main measure for increasing electrical safety.
