Workplace narrative
The factory is ramping up for the afternoon run and the switchboard is yours. Every machine you bring online adds current to one of the three phases - and the electrical supervisor warned that the imbalance alarm threshold is tight today. Meet the production demand, but keep the phases close. A badly balanced board means extra heating in the neutral, torque pulsation in the motors and a very unimpressed supervisor.
Why this skill matters
Phase balancing and switching judgement are core skills for industrial electricians and power engineers. Strong performance feeds the Electrical and Power/Energy pathways.
Learning objectives
- Read phase currents and calculate imbalance
- Choose which loads to run to meet demand
- Keep imbalance inside the operational limit
- Understand why balanced phases matter to motors and neutrals
Equipment and components
Three-phase switchboard (3D)Pumps, fans, crushers and heatersPhase ammeters A / B / CImbalance alarmSwitchgear and breakers
Technical principles
- Balanced three-phase loads draw equal currents and cancel neutral current
- Imbalance forces extra current through the neutral and heats machines unevenly
- Demand and balance are separate constraints - both must be satisfied
- Single-phase loads (like heaters) must be spread thoughtfully across phases
How to play
- Read the task demand and imbalance limits at the top
- Toggle machines on and off with the buttons
- Watch the phase meters and the imbalance readout update
- Press Check balance when you believe both constraints are met
Rules
- Each simulator task is worth 10 points plus streak bonuses
- Wrong attempts return you to the simulator to adjust and retry
- Pass each level with 70% or more
Formula and calculation section
Phase Imbalance
Imb% = (Imax - Imin) / Iavg x 100
The spread between highest and lowest phase current as a percent of the average.
Three-Phase Power
P = sqrt(3) x V x I x PF
Total power delivered across all three phases.

Your shift briefing
The factory is ramping up for the afternoon run and the switchboard is yours. Every machine you bring online adds current to one of the three phases - and the electrical supervisor warned that the imbalance alarm threshold is tight today. Meet the production demand, but keep the phases close. A badly balanced board means extra heating in the neutral, torque pulsation in the motors and a very unimpressed supervisor.
Feedback approach
After every attempt the meters stay visible so you can see exactly why the board passed or failed the check.
Common mistakes
- Meeting demand while ignoring imbalance
- Stacking single-phase loads onto one phase
- Expecting neutral current to stay high when phases balance
- Forgetting that turning a machine off can fix imbalance as fast as turning one on
