Substation testing & equipment management
Pleng captures your transformer, switchgear and cable test results, keeps track of every piece of substation equipment, and turns years of readings into clear, confident analysis.
Built by substation testing engineers — industry practice since 2003.
Two decades of field experience
An industry practice since 2003, distilled into one platform you can trust with your most important records.
What Pleng does
Everything you record in the field, organised and ready to act on — no more scattered spreadsheets.
Record transformer, switchgear and cable tests in a structured, searchable database — with the right fields for each test type.
Keep a live inventory of all your substation equipment, across every customer and site, with full test history attached.
Turn years of readings into clear charts and trends, so you can spot equipment drifting out of spec before it fails.
Role-based logins for Admins, Engineers and Viewers keep your data secure and your customers seeing only what they should.
How it works
Carry out your routine and diagnostic tests at the substation, just like you always have.
Enter the results against the right asset — on your phone, tablet or laptop, even offline.
Review trends, compare against history, and share clean results with your team and customers.
