01
Oilfield transformer selection
For oil production, gathering stations and ESP systems, selection begins with the motor load, drive output, cable voltage drop, duty cycle and field environment.
SHENYANG TEDA TRANSFORMER FACTORY / ENGINEERING
Industrial transformer engineering selection
Start with the actual application, load, system voltage, operating environment and interfaces. Shenyang Teda Transformer Factory turns project data into a practical transformer specification for new, replacement and retrofit projects.
01 / APPLICATION
Select the transformer around its duty
A transformer used in an oilfield drive, refinery process unit or plant distribution system may share a voltage class yet require a different electrical and mechanical design.
02
Refinery transformer selection
For crude-oil desalting and dehydration, the high-voltage power unit is coordinated with the process vessel, electrostatic field, regulation method and plant control interfaces.
03
Industrial power transformer selection
For plant distribution and dedicated industrial loads, we review system voltage, load behaviour, cooling, protection and installation constraints as one engineering task.
02 / PROJECT STAGE
New build, replacement or retrofit?
The project stage changes which documents matter most and how the transformer specification should be verified.
New installation
Start from the application, load list, system voltage and site conditions to establish the transformer specification and supply boundary.
Replacement transformer
Use the existing nameplate, drawings, mounting footprint and terminal arrangement to review a compatible drop-in replacement.
System retrofit
Recheck ratings, controls and interfaces when capacity, process duty, connected loads or the plant control philosophy changes.
03 / TECHNICAL INPUT
Six inputs define the transformer specification
Rated power and voltage are the starting point. Load behaviour, interfaces and site constraints determine whether the proposed transformer will fit the complete system.
Application and duty
Process equipment, operating cycle, expected loading and redundancy requirements.
Power and load profile
Rated power, continuous or cyclic load, overload duty, harmonics and starting conditions.
System voltage
Primary and secondary voltage, frequency, grid variation, taps and regulation range.
Control interfaces
VFD output, control cabinet, protection, interlocks, monitoring and remote signals.
Site environment
Ambient temperature, altitude, humidity, salt mist, dust and hazardous-area classification.
Installation boundary
Footprint, terminal direction, cooling, cable routing, transport limits and delivery scope.

06 / FAQ
Transformer selection questions
01What information is needed for transformer selection?
Application, rated power, primary and secondary voltage, load profile, operating environment and system interfaces form the basic selection input. The exact list depends on the transformer duty.
02How is a replacement transformer specified?
Begin with the existing nameplate and drawings, then verify the actual load, footprint, terminals, cooling, protection and any operating problems before freezing the replacement specification.
03Can Shenyang Teda Transformer Factory start without a complete transformer datasheet?
Yes. A single-line diagram, nameplate, load data or site photographs are enough to begin. Missing technical inputs can be identified during the engineering review.
