Prompt
**“Create an extremely detailed, photorealistic, PBR-ready 3D model of a large 440 kW high-voltage substation power transformer. The model must include accurate industrial geometry, clean topology, and full 360° detail. The transformer should be based on real heavy-duty ONAN/ONAF cooled power transformers with both forced air cooling and radiators. MAIN STRUCTURE (FULL DETAIL) – Large rectangular transformer tank with reinforced welding seams, bolt flanges, lifting lugs, base beams, and support legs – Radiator fins on the right side with multiple banks of cooling fans (3–8 fans), realistic brackets, wiring conduits, and motor housings – Conservator oil tank mounted on top with end caps, support brackets, sight glass, oil level gauge, and breather connection – HV & LV bushings on the top: tall porcelain/epoxy bushings, metallic terminals, nuts, connectors, and arcing horns – Cooling oil piping network: inlet/outlet pipes, isolating valves, bends, clamps, and welded joints – Realistic cable trenches, thick power cables, and flexible conduits entering the control cabinet CONTROL & PROTECTION DEVICES (MANDATORY) Integrate all standard transformer monitoring & diagnostic sensors: Winding Temperature Indicator (°C) – Analog dial or digital display – Mounted on the control cabinet – Include capillary tube or RTD connection Top Oil Temperature Indicator (°C) – Mounted near upper tank or control panel – With sensor bulb and protective piping Oil Level Indicator – Transparent gauge on conservator – Markings for MIN / MAX – Realistic oil inside Oil Moisture Sensor (ppm) – Installed on lower oil pipe – Show wiring connector and sensor body DGA (Dissolved Gas Analysis) Sensors – Gas manifold attachment with valves – Individual labeled sensors for: – Hydrogen (H₂) – early fault detection – Acetylene (C₂H₂) – arcing indicator – Carbon Monoxide (CO) – cellulose insulation failure OLTC (On Load Tap Changer) – Dedicated OLTC chamber on the side – Tap position indicator (digital/analog) – OLTC motor drive mechanism with wiring box – Include motor current monitoring unit Buchholz Relay (Mandatory) – Installed between main tank & conservator – Add float mechanism, alarm & trip pipe connections – Transparent or semi-transparent casing ADDITIONAL HIGH-DETAIL COMPONENTS – Silica gel breather with color-changing desiccant (blue/pink) – Pressure relief valve on top – Nitrogen release valves – Nameplate with engraved details (voltage, rating, serial no., manufacturer) – Earthing terminals & copper straps – Anti-vibration pads under base – Cooling fan junction box – Cable glanding plates – Ladder / maintenance steps (if applicable) PBR TEXTURING REQUIREMENTS – Painted steel surface (grey/blue industrial finish) – Slight wear: dust buildup, subtle rust at edges, oil stains near pipes – Realistic metal roughness, weld bead normal maps, bolt head details – Radiator fins must have micro-shadows and depth – Fans must have metallic shadows, reflections, and realistic blades OPTIONAL ADVANCED ADD-ONS (INCLUDE ALL) Internal Cutaway Model (Optional Layer) – Show transformer core (3-leg laminated core) – HV & LV windings (cylindrical, layered) – Insulation barriers – Oil flow channels Animated Parts Support – Cooling fans rotatable – OLTC tap changer motor animatable – Oil level movement Engineering-Accurate Scaling – Realistic dimensions (3–4 m long, 2–3 m high, heavy industrial scale) Clean Quad Topology – No mesh noise, no artifacts – Suitable for Blender, Unreal, Unity Export Format Requirements – Output in GLB or OBJ with full PBR textures: – BaseColor – Metallic – Roughness – Normal – Height / AO (optional) FINAL REQUIREMENT – Produce a complete, realistic 360° 3D model with all components, sensors, wiring, piping, structural detailing, industrial materials, and operation-accurate accessories.”**
