A separating transformer is a device that is designed for the so-called galvanic separation of electricity consumers and their electrical network.
The main task of such a device iscall for increased safety due to the fact that equipment such as a separation transformer does not have electrical connections to the secondary circuits with earth or with voltage sources made in the form of a grounded or effectively grounded neutral at transformer substations.
In this situation, even the emergence of a possibleelectric breakdown on the housing will not cause an overload on the electrical current. The device itself will remain in perfect working order. If an individual touches a part of the device that is under emergency voltage, the leakage current will not exceed the life-threatening level for a person, and as a result of the tragedy it will be possible to avoid.
The separating transformer will not be superfluous, not only at industrial enterprises, but even at home. Especially if there is a home workshop.
At the heart of such a device as a transformerseparating, lies the so-called TS (transformer unified). Since modern household electrical appliances are of different energy intensity and power, unified transformers are also taken with the calculation for a variety of load types and load power values.
The effect of separation and lack of electrical(which leads to the so-called galvanic isolation of the voltage that feeds the device, and the voltage that is supplied from the electric supply lines) is achieved very simply. The separating transformer has in its design two windings - secondary and primary. Between them is installed reinforced (no less than double) insulation or a metal grounded valve, which allows you to guarantee the avoidance of breakdown. Since the isolation transformer is not intended for voltage conversion, its transformation ratio is usually one. In this case, the voltage at the input will differ from the output voltage.
However, what then is the use of such atransformer? This is easy to demonstrate by example, if in a damp place, for example, in the bathroom there is an electrical point without galvanic isolation. In the event that moisture gets to such a point, an insulation breakdown will occur. As a consequence, some section of the wall and ungrounded electrical appliances next to it will fall under the influence of tension.
If there is an insulation breakdown and with a separationtransformer, the same part of the wall can also be energized, but in this case the current will be the lowest. And if there is no breakdown of insulation, the calculation of such a device as a separating transformer is chosen correctly, then there will be no current or voltage at all.
Such a device is often used in medicine. It is possible to use it as an output transformer or as a binder transformer to match the resistance of the circuit.
