Feedback from EPC, Oil & Gas, and Power sector engineers who completed QUECI programmes on NexUday.

★★★★★

"The Buchholz relay inspection module alone was worth the subscription. The IEC clause cross-references in every slide are something I hadn't seen in any other training."

Vikram Kulkarni

Senior Electrical Inspector · ONGC

★★★★★

"Finished CT & VT and Power Transformer in two months. The Accept/Caution/Record/Reject framework changed how I write FAT reports on site."

Priya Mehta

Electrical TPI Inspector · Bureau Veritas

★★★★★

"The GIS SF₆ handling module is the best structured content I've found for inspection engineers. Real factory scenarios, not textbook theory."
