Electrical PPE Mini Sim
By Excelsior College
This activity is a simulation that allows the learner to practice personal protective equipment tasks.
Three-Phase Delta Transformer Calculations
By James Bourassa
Using a memory shortcut for calculations, the learner determines line and phase values of current in a three-phase AC configuration. Practice problems complete the activity.
Three Phase Wye Transformer Calculations
In this interactive object, learners follow steps to find phase voltages in a partial three-phase power distribution circuit.
Selecting a Proper Single Phase Transformer
By Gary Lindell, Terry Bartelt
Students follow the steps that are required to select a transformer with the proper ratings. Voltage, frequency, current, and KVA are considered.
