What’re Isolation Transformers and what’s their significance in fluctuating power grids networks.
✓ An isolation transformer is a transformer that isolates two circuits or systems by transferring electrical power between them without any direct connection.
✓It does this using a unique winding technique, which allows the current to flow through the primary and secondary coils of the transformer without ever connecting to each other.
✓This provides complete electrical isolation between the two circuits, which helps protect against interference and potential damage from electrical surges.
• Types of Isolation Transformers: –
Available in several different types, each designed for a specific purpose.
Here are the most common types.
1. Constant Voltage Transformers also known as CVTs, are very common type of isolation transformer used to maintain a steady voltage output over varying input voltages and current levels. They work by using an autotransformer and feedback circuit to detect changes in the output voltage and make adjustments accordingly. This helps ensure that electrical devices connected to the transformer receive a constant voltage, even when there are fluctuations in the input voltage. Some other types of isolation transformer which are used for very precise voltage level.
2. Ultra Isolation Transformers
3. Drive Isolation Transformers
4. Galvanic Isolation Transformers
5.Dry type Isolation Transformers
Followings are some benefits of isolation transformer: –
1.Better Power Quality
2. Less Noise Disruption
3. Harmonics Correction
4. Safety of Equipment
5. unwanted Power surge protection
6. Earthing failure protection Overall, isolation transformers are a type of transformer that provides complete electrical insulation between two circuits or systems. This helps to ensure the highest levels of safety and reliability by providing clean, consistent power without any interference or fluctuation in voltage. Furthermore, isolation transformers can also help to protect against potential damage caused by electrical noise or surges, reduce noise disruption, correct harmonic distortion, and prevent earthing failure.
In special industrial zone, where grid power is fully loaded and very much how injected with solar connectivity , Isolation transfers are much more relevant. Sudden loading and unloading of solar load at mass level as well as in fault conditions dip and surge in RMS voltage level is obvious and enough to create disturbance to electronics devices.
Isolation transformer are also beneficial where there’s big gap between HT and LT voltage level of power and distribution transformer.
