Checking your tools account…
Start with a simple experiment
- Create a tools account with your name and specialty, then use the browser simulator.
- Choose balanced currents, then a phase-to-earth example. Compare Ig and FAULT N.
- Use the relay LCD: MENU opens menus, UP/DOWN navigate, ENTER edits and saves; MENU cancels an unsaved edit. Then calculate the injection to apply the values and compute the trip.
- Try SELECT then OPEN or CLOSE. RESET clears indicators and the shot counter; records remain until you leave the page.
Training only: an independent simplified model with no live device connection. Do not use it to approve protection settings. Trip delay is calculated immediately, not measured in real time. Only NI, VI and EI curves are calculated; automatic reclosing is not implemented.
Windows includes the original application interface and menus. The web edition provides a responsive training interface for supported elements; the native phone app is deferred.
