Product Description

Product Description

Potential Transformer

*1000kVA transformer with no-load loss as low as 0.35kW, Level 1 energy efficiency reduces carbon by 120t, energy-saving and eco-friendly.

*99.6% full-load efficiency, 15% lower no-load loss than national standard, ultra-efficient power conversion.

*Withstands 2g short-circuit impact, partial discharge ≤10pC, excellent insulation and mechanical performance.

*150% rated load operable for 30min, strong overload capacity, calm in face of power peaks.

*Dry-type transformer with design life ≥30 years, IP54 protection for -25℃~40℃, durable and adaptable.

Potential Transformer

*Dry-type transformer capacity increases by 40% with FA, fan air volume 800m³/h, heat dissipation efficiency surges 50%.

*1000kVA dry-type transformer noise ≤55dB(A), 8dB(A) lower than traditional ones, quieter industrial environment.

*Tap changer adjusts ±5%, voltage regulation rate ≤±2%, ultra-precise output voltage.

*Endures 15% 3rd/5th harmonics, harmonic loss increase ≤8%, suitable for new energy grid connection.

No-load closing inrush current only 3-5 times rated current, greatly reducing grid impact for more safety.

FAQ

Please enter the title here

1. Q: How to select the right transformer capacity (kVA)?
A: Calculate total connected load power, add 20%-30% margin for overload/expansion; formula: kVA ≥ total load power (kW) / load power factor.

2. Q: What's the difference between copper and aluminum windings?
A: Copper has lower resistance, higher efficiency, better heat resistance and durability, but higher cost; aluminum is cheaper but requires larger cross-section for same current.

3. Q: Can a 50Hz transformer be used with 60Hz power, or vice versa?
A: Generally not recommended. Deviation in frequency will change core loss, impedance and cooling performance, possibly causing overheating or damage.

4. Q: Why does a transformer hum? How to reduce it?
A: Mainly from magnetostriction of the core under AC. Solutions: Use low-noise core materials, improve clamping, ensure no DC in windings, and proper installation.

5. Q: What are the main losses in a transformer?
A: Iron loss (hysteresis + eddy current, constant with load) and copper loss (winding resistance loss, load-dependent).

6. Q: How to handle transformer overheating?
A: First cut off load and power; check cooling system, ventilation, loose connections, overload or internal faults, then troubleshoot and repair.
