200kva 3 phase isolation transformer
When system stability matters, isolation isn’t optional—it’s essential.
For integrators building multi-bay automation lines, or OEMs powering sensitive loads like CNC, drives, or medical electronics, this 200kVA isolation transformer provides what power conditioning can’t: true galvanic isolation, noise suppression, and circuit protection—all in one standardized unit.
Every Shinenergy transformer ships pre-tested, UL-labeled, and ready to deploy across facilities. We maintain consistent build specs, labeling, and enclosure formats so your team doesn’t waste time adapting layout. One part number. One wiring diagram. From Boston to Berlin.
Photovoltaics：AC output stage after string inverters
In a large-scale PV plant in Tucson, Arizona, the 200kVA isolation transformer was deployed to decouple the inverter bank from the local utility grid. This setup prevented backflow disturbances and met NEC 690.35(E) isolation requirements. For EPC firms managing solar farms across multiple states, the standardized 3-phase model streamlined procurement and site commissioning.
Energy Storage：Between battery inverters and control cabinets
A 100MWh battery energy storage system in Rotterdam, Netherlands, utilizes our 200kVA isolation units to stabilize auxiliary power channels. These transformers protect sensitive control electronics from high-frequency noise originating from bidirectional inverter operation. Integrators appreciated the consistent terminal layout across units—saving hours during multi-site deployment.
Data Centers：Between UPS and downstream IT loads
In a tier-3 colocation facility near Frankfurt, Germany, Shinenergy’s 200kVA 3-phase isolation transformer ensures galvanic separation between UPS systems and server room PDUs. By mitigating common-mode noise, it preserves signal integrity for network routers and storage arrays. Facility managers highlighted the silent operation and compact form factor as key advantages.
Wind-to-Hydrogen:Power interface for PEM electrolyzer control panels
A wind-powered hydrogen project in North Yorkshire, UK, incorporated this transformer to feed the DC rectifier and process controller safely from the wind farm’s internal grid. Isolation not only stabilized power supply but also fulfilled local electrical separation codes. For hydrogen integrators working with multiple OEMs, the transformer’s flexible mounting options made cabinet integration seamless.
Medical Systems:Shielding medical imaging equipment from upstream interference
A radiology wing at a hospital in Chicago, Illinois, replaced its legacy shielded transformer with Shinenergy’s 200kVA isolation unit. It now delivers clean, isolated 480V power to CT and MRI machines, ensuring electromagnetic compatibility and patient safety. Hospital engineers noted smoother imaging cycles and fewer equipment alarms post-installation.

Why Isolation Still Matters in Modern 3 Phase Systems
In a world of smart devices, filtered power supplies, and digital circuits, you’d think electrical isolation is overkill. But if you’re running sensitive loads—like servo drives, hospital imaging systems, or inverter-fed equipment—you still need it.
A 3 phase isolation transformer isn’t just a voltage block. It’s a system-level filter, a noise shield, and a compliance tool. It protects against upstream transients, stops circulating currents, and brings your grounding plan into order.
Whether you’re wiring a 480V 3 phase isolation transformer for a chilled water pump or dropping in a 200kVA unit at the edge of a solar BESS skid, it’s all about repeatability. You want standard wiring diagrams, clear schematics, and matched specs—so your crew isn’t wasting time figuring out how to land wires every time.
At Shinenergy, we make that easy. Every unit ships tested, labeled, and consistent—because isolation doesn’t work if your team’s installation is chaotic.
It electrically separates the primary power source from the load. Commonly used to reduce ground loops, suppress electrical noise, and provide clean, isolated power for CNC, UPS systems, or industrial controllers.
Prices vary based on capacity, voltage, and enclosure type. A standard 200kVA 480V 3 phase isolation transformer might cost between （Contact Us） depending on certification, winding material, and delivery terms. For project pricing, we quote per batch and spec.
Yes. All Shinenergy units ship with a dedicated wiring diagram and schematic showing terminal connections for both primary and secondary windings—Delta or Wye—along with grounding guidance.
No—both refer to the same function: isolating a 480V 3-phase supply from its load. Some clients use the terms interchangeably in specs and RFQs.
Our schematics include: core configuration, tap settings (if applicable), terminal identifiers, shielding info, and grounding scheme. Perfect for cabinet integration and UL/IEC inspections.
Start with your full load amps (FLA), multiply by √3 × voltage to get kVA, then add 20% safety margin. For automation systems or data centers, it’s common to standardize on 150kVA or 200kVA models for branch-level isolation.
Typically, input connects to L1-L2-L3 from utility or UPS, and output goes to load-side panel or PDU. Grounding strategy depends on whether Delta or Wye is used. For data centers, Wye secondary with grounded neutral is standard.
