Industrial Electrical Symbols With Technical Metadata

33,502 PNG images depict industrial electrical symbols from standards including EPLAN IEC, NFPA, and GB. The dataset was curated by Covaga and includes complete technical metadata and AI-generated visual descriptions for each symbol. It was last updated on April 3, 2026.

Use Cases

• Train a symbol classifier model using the 33,502 PNG images and their associated standard labels (EPLAN IEC, NFPA, GB).
• Develop an industrial schematic OCR system by leveraging the AI-generated visual descriptions for each electrical symbol.
• Build a vision RAG system for automation engineering using the dataset's complete technical metadata associated with each symbol image.
• Fine-tune object detection models to locate and identify specific electrical symbols within larger engineering schematics.

Strengths

• Contains 33,502 individual symbol images for model training.
• Includes symbols from multiple international standards (EPLAN IEC, NFPA, GB).
• Each image is paired with complete technical metadata and an AI-generated description.

Limitations

• No column or sample data is provided to verify the structure of the technical metadata.
• The dataset's license, file formats, and exact size are unknown.
