Normative Disclaimer

Ohmly is an open-source engineering support library, distributed under the MIT License.

It is intended to assist in the mechanical analysis of overhead conductors, but it is not a certified calculation tool and does not replace professional engineering judgment, regulatory review, or a complete project analysis.

Regulatory Scope

  • Mechanical calculations currently implemented in Ohmly follow Spanish regulation ITC-LAT 07 only.
  • No other standards or national codes are supported unless explicitly stated.
  • The user is responsible for ensuring that ITC-LAT 07 is applicable to their project and jurisdiction.

Engineering Responsibility

  • All results must be verified and validated by a qualified engineer before being used for design, construction, or regulatory submission.
  • Input data quality and correctness are the sole responsibility of the user.
  • Incorrect assumptions or misuse may result in non-compliant or unsafe designs.

Data and Assumptions

  • Built-in conductor data is based on UNE-EN 50182 standard values.
  • Actual conductor properties may differ depending on manufacturer, installation method, accessories, and service conditions.
  • Ohmly allows manual modification of properties to reflect real-world data.

License and Liability

  • Ohmly is provided “as is”, without warranty of any kind, as stated in the MIT License.
  • The authors and contributors accept no liability for damages, losses, or consequences arising from the use of this software.

Intended Use
