The issue of three-phase balance in UPS systems
Thread Content
According to the HG/T20509 regulations for instrument power supply design, when the UPS supplies three-phase power, attention must be paid to the balance of power consumption across the three phases. How should this balance be ensured in the design?
Just ensure even distribution when distributing the power; you’re definitely not in an electrical engineering field, right?
What will be the consequences if it’s uneven?
There are no consequences; uniformity is aimed at achieving high efficiency in energy utilization
The load on the power supply units is usually not high. The 80KVA UPS we use has a load capacity of less than 10% under normal conditions; with a little care, there will be no problems
