Isolation Transformers Canada

Generally used for isolating a section of the current flow, Isolation transformer, as the name suggests, transfers power to a device that is isolated from the power source for safety reasons. They transfer power from one voltage level to a different level while keeping the same frequency.

What is Isolation Transformers?

The isolated power transformer has a secondary winding that is physically separated from the primary winding. They are coupled magnetically but never linked with each other.

The biggest advantage of an isolated auto transformer is that it blocks the DC signals while letting the alternating current pass to the device. Isolation and power transformer manufacturers develop them with 1:1 ratio between primary and secondary windings. It safeguards them from electric shocks that might occur in the ground and electric conductors.

This article will highlight a few benefits of the isolation transformer and why it is used widely for transferring AC to powered devices. Let’s see how the isolation power transformer manages to bear voltages between 1000 to 4000 volts.

Benefits of Isolation transformers

Today, isolation power transformers are widely used to regulate the voltage capacities of alternating current. Power transformer manufacturers provide isolation transformers for different types of businesses and industries, depending upon their usage.

Here are a few benefits of an isolation transformer

  • Facilitate DC isolation

Isolation transformers are excellent at facilitating DC isolation. In devices that require amplification at regular intervals, it is necessary to isolate direct current. They separate the DC components and let the current flow in the direction of the usage. It helps in controlling the signal of each and every amplifier that is used in the device.

  • Reduction in surges

Since the DC components are separated with the help of isolation auto transformer, they reduce power surges. Any electrical equipment can run efficiently without the risk of current overload that might occur due to DC signal. It means that the device can perform at a higher level even when there is a power malfunction because the components are sorted.

  • Safety

Any defective equipment and live wires can lead to electric shock and great hazards. Isolation transformers are necessary in places like hospitals and industries to keep the wiring safe and risk-free. They are used to isolate the components and provide the utmost level of safety. It also provides reliable and accurate measurements in every aspect.

  • Less noise

Isolation transformer is the perfect choice because it leads to less noise in the electrical system. There are Faraday shields that filter the noise through the power lines. These shields block the electric field from blocking the power flow. So when there is less magnetic interruption, it automatically leads to reduction in noise while the transformer is in operation.

  • Enhanced power quality

The Faraday shields help in reducing the chances of potential power leakage. They keep the current flow intact, and that’s why the isolation power transformer is mostly used in industrial places. They keep the power quality high by constantly delivering the right amount of voltage level. Therefore, essential electrical equipment can operate at the optimum level.

  • Diverse applications

An isolation transformer has a wide variety of applications. It is used for isolation of pulse circuits, providing electrical isolation in medical equipment, in devices that are not at ground supply, and for electronics testing and safety purposes. They ensure that a live part of the circuit doesn’t touch with the other and keep potential hazards at bay.

Isolation transformers are highly useful in places where there is a heavy requirement of controlling and separating the direct current components. In managing the voltage level, an isolation power transformer is a useful piece of equipment.
