Introduction:
In the dynamic world of electrical engineering, the role of transformers has become more demanding and more specific. Among the plethora of transformers available, ISOLATION TRANSFORMER stand out as indispensable device for various industrial applications. With its 30 years of experience in this field, ELECTRO SERVICE INDIA has mastered the art of manufacturing of Isolation Transformers. This blog explores the nuances of Isolation Transformers, their applications and the distinctive advantages of choosing Electro Service India for your transformer needs.
What is an Isolation Transformer?
An isolation transformer is an important electrical machine/component for critical applications in the domain of electrical engineering. Like any other transformer, Isolation Transformer is also galvanically isolated and electro-magnetically coupled device. But, Isolation Transformer provide very high galvanic insulation between primary and secondary circuits. The insulation resistance between primary and secondary circuits goes beyond 1000 Meg Ohm at 1000V DC.
Isolation Transformer ensures hundred percent safety with regard to shock to the users of equipment connected in the secondary circuits.
The versatility of isolation transformers makes them indispensable in diverse applications. Electro Service India’s range of Isolation Transformers are installed in various sensitive sites.
Few important applications are:
Industrial Machinery:
- Isolation transformers play a pivotal role in safeguarding industrial machinery from electrical noise and disturbances. They ensure that sensitive equipment operates seamlessly, free from potential disruptions caused by power fluctuations.
Healthcare Facilities:
- In medical settings, precision is paramount. Isolation transformers are extensively used in healthcare facilities to protect medical equipment from electrical interference, providing a stable power supply for critical devices.
Information Technology (IT) Infrastructure:
- Isolation transformers play a pivotal role in IT setups, shielding electronic equipment from power surges and ensuring data integrity. These transformers act as a barrier against electrical noise that may create an undesirable disturbance to the sensitive IT networks and installations.
Salient Features of Electro Service Isolation Transformers:
- Reduction of Capacitive coupling: All Isolation Transformers manufactured by Electro Service India are embedded with a “Farady Shield” between Primary and Secondary for minimizing the capacitive coupling between them. This enhances the Isolation.
- Moisture Proofing: Each and every transformer manufactured at Electro Service works undergoes impregnation with high-quality Class-F Varnish in a Vacuum Impregnation Plant.
- Winding Insulation: Electro Service India uses high quality Class-F grade super-enameled copper wire and Nomex (class-H) insulated copper strips to provide best inter-turn insulation. Inter-layer insulations are provided with polyester films of high di-electric strength. Multiple insulated polyester films along with a faraday shield in between two windings provide excellent inter-winding insulation.
- Cooling: While designing the transformer coils we provide sufficient surface area for heat dissipation of coils under operation. At Electro Service India we implement ducting in larger transformers for increased airflow between windings. This technique ensures excellent thermal performance and stability.
- Core Materials: Core material is the heart of a transformer. At Electro Service India we understand its significance and use CRGO or high permeability electrical grade laminations, which minimizes core losses, reduces excitation current, and guarantees cooler, quieter operation.
- Testing and quality assurance: Electro Service India goes the extra mile to ensure the quality of its products. Every transformer undergoes routine testing as per industry standards (IS2026 or IS6297), and a manufacturer’s routine TC accompanies each supply. This commitment to quality instills confidence in client’s mind about the reliability of Electro Service India transformers.
Conclusion:
In the realm of electrical engineering, Electro Service India stands tall as a pioneer in manufacturing ISOLATION TRANSFORMERS that redefine industry benchmarks. With a focus on safety, performance and reliability company’s transformers find applications across diverse sectors, from industrial machinery to healthcare facilities and IT infrastructure. The advantages of choosing Electro Service India, as highlighted, make it clear that Electro Service India can be considered as trusted partner for Transformers in ever-growing electrical industries.
