V. FAQs
Q1: How should I choose a transformer for different production modes?
A: Choose based on production intensity:
– Single-shift production: 125kVA
– Double-shift production: 160kVA
– Continuous production: 200kVA
Q2: What are the effects of grid voltage fluctuations?
A: When the voltage fluctuates by ±10%:
– A 125kVA transformer may be overloaded
– A 160kVA transformer can still operate stably
– It is recommended to install a voltage stabilizer
