When dealing with high-capacity, three-phase power, reliability and protection are non-negotiable. Our isolation transformers (up to 1500 kVA) are engineered for the demanding needs of industrial facilities, data centers, and large commercial operations, providing superior power quality, noise attenuation, and personnel safety.
Why Is 3 Phase Isolation Essential for Your Operations?
In high-power environments, disturbances from the main utility are magnified. Our 3 Phase Isolation Transformers provide Galvanic Isolation—the complete electrical separation of the source from your sensitive load. This separation is crucial for:
- Protecting Critical Infrastructure: Shielding expensive machinery, PLC systems, and data center UPS systems from severe transient voltages and surges.
- Eliminating Industrial Noise: Stopping electrical noise and ground loops generated by large motors and Variable Frequency Drives (VFDs) from disrupting control circuits.
- Uncompromising Safety: Creating a safe, isolated secondary winding that ensures personnel protection, significantly reducing the risk of shock from ground faults.
Key Operational Advantages for Industrial Buyers
This high-capacity unit is built with specifications that guarantee peak performance in rugged environments:
1. Superior Power Quality and Filtration
The high Common Mode Attenuation (80 db / 100 db) ensures that electrical interference is drastically minimized, which is essential for stable operation of sensitive industrial controls and communication equipment.
2. High-Capacity Flexibility and Reliability
We offer two critical voltage options based on your facility’s needs:
- 415V:415V (1:1 Ratio): For pure isolation and noise cleaning without altering the voltage level—ideal for data center UPS systems and main industrial distribution panels.
- 415V:220V (Step-Down Ratio): For safely supplying large 3 Phase machinery or secondary distribution circuits that require the $220\text{V}$ standard, all while maintaining full isolation.
3. Safety and Robustness
Our transformers are designed for stability and safety, featuring extremely low Leakage Current (Less than 20 Micro Amps) and a high Di-electric Strength, providing protection that meets rigorous IS 2026 construction standards.
Ideal Applications for High-Capacity 3 Phase Isolation

| Commercial Distribution | 415V:220V | Supplying clean, isolated 220 V power to large commercial distribution panels and specialized building equipment from a 415 V main line. |
| Medical/Testing Facilities | 415V:415V | Providing a highly stable and safe power source for centralized testing labs and sensitive diagnostic equipment. |
Required Customer Inputs for Exact Specifications
To ensure we configure the perfect 415 V 3-Phase Isolation Transformer (up to 1500 kVA) for your needs, please provide the following technical details when requesting a quote:
| Input Category | Key Information We Need | Determining Factor |
| Total Load Requirement | What is the maximum power requirement in kVA for all connected equipment? | Critical for determining the transformer’s capacity (e.g., 500 kVA, 1000 kVA, etc.). |
| Output Voltage | Do you require 415V (1:1 ratio) or 220V (step-down ratio)? | Dictates the final winding configuration. |
| Operating Environment | Is this an indoor or outdoor installation, and what are the ambient temperatures? | Essential for specifying the appropriate Type of Cooling (e.g., forced air-cooled vs. oil-cooled). |
| Connection Scheme | Is your source and load side configured as Delta or Star? | Ensures compatibility with the transformer’s system connections (Delta / Star). |
