ENGINEERING FOR PERFORMANCE
OTC Services has an on-site design and engineering department staffed for electrical, mechanical and control engineering.
Our new transformers are designed and tested in accordance with the latest ANSI/IEEE standards and are designed to fit your required profile of existing or newly manufactured electrical systems.
​
When remanufacturing your transformer our engineers design your transformer to eliminate weaknesses found that may have caused the failure. We provide a detailed inspection report before we begin.

ELECTRICAL TOOLS
Anderson FLD12
- Calculates the impedance and simulates short circuit faults, and axial and radial forces and stresses in the winding.
​
Ansys
- Helps solve any electromagnetic field problem
- Verifies all dielectric clearances
- Calculates eddy and stray losses accurately
​
Impulse Voltage Distribution Program
- We verify our designs for impulse test by using impulse voltage distribution program developed by SGB Germany.
​
Design Calculation Sheet
- Creates the axial and radial copper and insulation distribution in the transformer core window and calculates the impedance, losses and material weights
- Program determines the most cost effective design for the customers technical specification
- Calculates the core step dimensions for the optimal fill factor
- Generates the bill of materials
- Calculates winding gradients, core gradients, winding hot spot and oil temperature rises
​
AutoCAD

MECHANICAL TOOLS
SolidWorks
- Creates complete 3D model of the transformer
- 3D model allows verification of all critical dimensions, performs mechanical calculations and creates drawings
- 3D simulation package allows checking of all mechanical stresses in the material

CONTROL TOOLS
SolidWorks Electrical and AutoCad
- Control engineer uses AutoCad to create 2D wiring diagram and SolidWorks Electrical to create complete 3D model of control system of the transformer
- SolidWorks Electrical can do all point to point wiring automatically so it reduces errors in wiring and numbering.
