The isolation transformer manufacturer supplies the market with many models with different characteristics. For practical purposes, it is sufficient to know the basic parameters of the transformer. Usually, these parameters are specified in the device passport. If you are looking for an isolation transformer at a good price, you have several options, one of the most popular of which is to search for it on the Shakti Transformer.

1. HOW ISOLATION TRANSFORMERWORK
Voltage 220 V is not safe for humans. Accidental contact with a live
wire or live instrument case can be fatal if the person is standing on
the ground or on a grounded surface. Of particular danger are the
mains current in wet rooms. An isolation transformer ensures the
safe operation of the equipment. It is used to decouple the galvanic
connection of the power supply with the mains voltage, which
reduces the likelihood of electric shock to zero.
What is Isolation Transformer?
In reality, a safety transformer or isolation transformer is referred to
very specific transformer with a 1:1ratio, i.e., with the same winding in
both coils (same number of turns), so as not to transform the servo
voltage stabilizer and thus, the output and input will be equal.
Isolation Transformer: Varieties
In electrical engineering, a step-down transformer offered by a step
down transformer manufacturer in jaipur with galvanic separation of
the circuits of the primary winding and the secondary coil is often
used.
The power transformer family includes a series of single-phase
transformers with different power ratings. Industrial power units are
usually of impressive size and are installed permanently in special
boxes.

2. The use of portable transformers is convenient in cases where
electrical equipment cannot be installed permanently but is used
periodically. At rated primary voltages, these devices work stably.
They are well protected from moisture and other environmental
influences.
In input signal blocks, as well as in other circuits of electronic
equipment, small-sized, high-frequency pulse booster transformers
are used. According to the design of the core, the network
transformer is most often of the rod type. There are also toroidal
models.
Isolation Transformer: Construction And
Principle Of Action
The main difference between the isolation transformer is the
absence of galvanic coupling between the coils, which are reliably
separated by galvanic isolation. Usually, the winding forming the
primary circuit of the transformer are identical in parameters to the
winding in the secondary circuits. In this case, the transformation
ratio for this isolating transformer is 1.That is, the device is used
exclusively for galvanic isolation.
A characteristic feature of transformers of this type is that the
circuits of the secondary winding in the dividing transformation are
not equipped with protective grounding. In order to ensure the
reliability of galvanic isolation, additional insulation is used between
the coils. In some cases, the turns of the primary windings are
separated by a protective screen from the secondary winding, or
they are physically separated into different parts of the magnetic
circuit.

3. Otherwise, the design and principle of operation do not differ from
other types of transformers:
Voltage is supplied to the primary winding from the network;
The resulting magnetic induction propagates throughout the
magnetic circuit.
The induction emf excites an electric current in the secondary
coil turns.
There is a relationship between the voltages in the coils and the
currents: the magnitudes of the secondary voltages are directly
proportional to the primary voltages, with a proportionality factor
k=W 2 /W 1,and the output current is inversely proportional to the
current in the primary winding.
Due to the absence of a galvanic connection between the coils and
the separation from the ground circuit of the primary winding,
accidental contact with any terminal of the secondary coil does not
lead to electric shock. It is only necessary to beware of touching
different terminals of the transformer at the same time.
Thus, in case of electrical contact with the current-carrying parts of
equipment powered by an isolation transformer, an electrical circuit
with the ground is not formed, which eliminates the possibility of
electric shock. Isolating transformers also provide protection for
connected electrical appliances in case of single-phase faults.
However, for complete protection, connect an RCD to the primary
circuit.

4. Isolation Transformer: Specifications
The isolation transformer manufacturer supplies the market with
many models with different characteristics. For practical purposes, it
is sufficient to know the basic parameters of the transformer.
Usually, these parameters are specified in the device passport.
When choosing an isolating transformer, pay attention to the
following main characteristics:
Rated power;
Current frequency;
Primary voltage;
Output (secondary) voltage;
Symbol of the winding connection scheme;
Voltage in short circuit mode;
Thermal losses during short circuits;
Current in idle mode;
Heat losses during idling;
Dimensions.
The rated power must match or slightly exceed the load power. The
primary voltage must correspond to the parameters of the primary
network, and the secondary voltage must correspond to the supply
voltage of the connected electrical appliances. When choosing pulse
transformers, pay attention to the frequency of the current.
If you are looking for an isolation transformer at a good price, you
have several options, one of the most popular of which is to search
for it on the Shakti Transformer.
