3 Phase Transformers
3 phase transformers are important components in 3 phase electric power transmission. 3 phase transmission is among the most common power transmission methods worldwide. It is one of several polyphase current transmission methods utilized by electric power companies and utility operators; the main advantage of polyphase transmission over single phase transmission is the increased electrical transmission capacity despite a lower requirement for transmission wires.
In order to manage a 3 phase electricity transmission system, 3 phase transformers are necessary to transform and direct electrical current away from power lines and into homes and places of business. A current transformer adjusts the current that flows from an electrical utility line into the systems that will make use of it.
Power transformers are essential to the safe and effective operation of electrical systems as well as individual appliances. In the case of 3 phase transformers, the transformer receives and distributes the power input at the appropriate voltage for equipment that requires 3 phase electricity. Large industrial equipment tends to require 3 phase electricity in order to function properly. 3 phase transformers are necessary for the distribution of power to such equipment. Less demanding equipment is usually equipped to two phase or single phase transformers.
A phase transformer is essential for the safe and effective distribution of power to homes and places of business. Every country has adopted a standard power outlet voltage output. The two most commonly used outputs are 120V and 220V. In order for outlets to provide appropriate voltages, a voltage transformer is necessary. Voltage transformers are also important parts of most electronic devices. Portable music players, telephones, video entertainment equipment and most everything else that is plugged into a wall outlet is equipped with its own individual voltage transformer. Once a transformer has reduced the amount of voltage available at individual outlets, that voltage must again be reduced by another transformer to levels appropriate for use by small electronic devices.
Small toroidal transformers can fit inside device power cables and even within the devices themselves, in some cases. It is important to always match input voltage with the instructions printed on an electrical device. A voltage mismatch, whether excessive or inadequate, can cause impaired function or damage to an electronic device.
