About 3 Phase Isolation Transformer

3 Phase Isolation Transformer

We have reached the pinnacle of success and earned a name as an eminent manufacturer and supplier of 3 Phase Isolation Transformer. At our sound production unit, we manufacture this transformer using high quality materials and components. This transformer is used in power plant, substation and mining enterprise. We make this 3 Phase Isolation Transformer available for clients in different technical specifications as per their requirements.

We manufacture Isolation Transformers, Step up Transformer, Step down Transformer which reduce the effects of power Line problems like noise, spikes, surges, transients and neutral, to a minimum. Isolation transformer is one that contains two windings: Primary and Secondary winding, that are separated from each othe but wound on the same Iron core. The secondary that governs the output is, in this manner, separated from the input. Input and output are totally independent of each other except for the magnetic linkage between the two.

RATING : 1 KVA 500 KVA (Single / Three Phases)

key Features:

This transformer are rugged in construction, free standing and floor mounting
The transformer is housed in sturdy metal casing with sufficient ventilation
Isolates the equipment from noisy power line

FAQ's of 3 Phase Isolation Transformer:

Q: How does the 3 Phase Isolation Transformer enhance safety in power systems?

A: By providing galvanic isolation between input and output, the transformer prevents electrical noise and surges from reaching sensitive equipment, thereby safeguarding both equipment and personnel against electrical faults.

Q: What are the available winding configurations and how do they impact installation?

A: The transformer supports both Delta and Star (Wye) winding configurations as per requirements. This flexibility allows compatibility with various three-phase systems and facilitates easier adaptation during installation.

Q: When should I choose air-cooled versus oil-cooled models?

A: Air-cooled (AN) transformers are ideal for environments with standard cooling needs, while oil-cooled (ONAN) units are preferred in high-load or harsher settings, offering enhanced thermal management for prolonged operation.

Q: Where can this transformer be installed and what are the enclosure options?

A: Designed for floor mounting, it can be placed in indoor or moderate outdoor settings. Enclosures are available in IP23 (for dry, protected spaces) or IP54 (for environments exposed to dust and moisture), ensuring adaptability to site conditions.

Q: What is the process for customizing voltage ratings or configurations?

A: Customization is available for rated voltages (380V/415V/440V) and winding materials. Discuss your requirements with the manufacturer or supplier, who will tailor the transformer's design to fit your specific application.

Q: How is noise level managed and why is it important?

A: Noise levels are kept under 65 dB at 1 meter, ensuring a quieter workplace and complying with industrial noise standards, which is important for employee comfort and meeting local regulations.

Q: What are the key benefits of using this isolation transformer?

A: Key benefits include high efficiency (>98%), strong safety features, versatility across industries, low maintenance, and reliable voltage regulation, making it a preferred solution for modern three-phase power distribution systems.
