P&C FIELDCHECK / SETTINGS & COMMISSIONING
From the drawing.
To the field.
With understanding.
Engineering tools for the people who protect the power system. Bring calculations, nameplates, and field references into one place.
A second check for the engineer and technician.
YOUR DIGITAL WORKBENCH
The app's tools.
Room to work.
Open a calculator at your desk or bring your field references along on your phone. Your inputs remain yours to review.
Start with the nameplate.
Read a photo, review the values, then explore winding connections, phase shift, CT polarity, and compensation.
Keep the field in context.
Scan the substation sign. Organize equipment photos, compare conditions, and record a second-look observation.

USING THE WEBSITE
Ready for your review.
How do I start?
Choose a calculator above, or open the equipment workspace. The transformer tool includes separate Learning and Commissioning modes. Review extracted nameplate values before applying them.
Can I move work to another computer?
Download a calculation-case backup, then import it on the other computer. Equipment ZIP exports include reports and photos for external reference; equipment ZIP import and automatic cloud synchronization are not implemented.
What needs a real-device check?
Camera capture and OCR accuracy depend on your phone, browser, image quality, and nameplate. The web reader uses bundled Tesseract; it is not Apple's native Vision reader or the desktop enhanced reader.
Where is my work saved?
Your records are saved in this browser on pandcfieldcheck.com. Export backups regularly. Moving from another website address does not automatically move its saved records.
