Load balancing in a three-phase distribution board – why it is important

What is load balancing

Single-phase loads must be distributed as evenly as possible across the three phases.

What happens when one phase is overloaded

• The current in a specific phase increases.
• There is greater thermal stress.
• Voltage drops may occur.

Verification

We measure the currents in the three phases under normal operation and redistribute loads where technically feasible.
