What are Isolation Transformers?


An isolation transformer, just like typical transformers, is a non-moving device that transmits electrical energy from one circuit to another without requiring any physical contact. It works on the idea of magnetic induction, which uses a magnetic field to induce EMF in another circuit without affecting the frequency. Transformers are used in transmission and distribution networks to step up and down voltage levels. An isolation transformer is a type of transformer that provides electrical isolation between two circuits (primary and secondary) without modifying the secondary properties (voltage, current, and frequency levels).


The primary coil circuit and secondary coil circuit of the isolation transformer are electrically isolated. As a result, isolation transformers refer to all transformers used in transmission and distribution networks. An isolation transformer is a device that transfers electrical power from an alternating current source to some equipment or device. This happens while isolating the powered device from the power source, primarily for safety or to reduce transients and harmonics.

Function of an Isolation Transformer


An isolation transformer provides the physical and electrical separation between two circuits. It isolates and protects electronic circuits and people from mainline electrical shock. Magnetic coupling is used to transfer electrical energy from primary to secondary. Isolation transformers are only used with transformers with a ratio of 1:1.


An isolation transformer's main purpose is to reduce voltage spikes in the supply lines. Illumination, static electricity, or a quick voltage change can cause voltage spikes, transients, and surges in electrical power supply lines. A voltage spike is a rapid increase in voltage levels that lasts for a short time (3 nanoseconds or more).


The voltage spikes carry high voltages ranging from a few to several thousand volts. If such high voltage spikes reach the load, they might cause service interruptions or damage equipment. The voltage spikes can be reduced before they reach the load by connecting an isolation transformer between the power supply lines.


Assume a spike of high voltage and current with fast change occurs on the isolation transformer's primary side (i.e., on the supply side). When a voltage spike passes through the primary winding, it is called a voltage spike. While the inductor resists a sudden shift in current, the inductive primary winding allows for an exponential shift in current rather than an instantaneous change.


The flux rises as the current rises, causing the voltage to rise in the secondary. The spike is prevented from reproducing in the secondary due to the inductive nature of the primary and secondary. In addition, the resistance to the current is proportional to how fast it changes. Because a voltage spike involves rapidly changing voltage and current, the resistance generated will be larger. As a result, the secondary or load circuit spike is considerably decreased, avoiding negative impacts on load equipment.


Another essential feature of an isolation transformer is that it prevents load equipment or the secondary side from being grounded. As a result, an isolation transformer eliminates ground loop interference and noise effects on the load. An isolation transformer protects sensitive equipment in measurements, laboratories, medical equipment, and other applications from voltage spikes, ground loops, and other power line distortions.


An isolation transformer is built similarly to a standard core-type transformer. Electrostatic shields entirely isolate the secondary from the primary, suppressing noise. Due to the electrical connection between the two windings, an autotransformer with a common primary and secondary winding cannot be utilized as an isolation transformer.
