Functional Principle of 20KV High Voltage Transformer Oil Immersed Power Transformer 100KVA-8000KVA Three Phase 380V Output

• Voltage conversion: The most basic function of a high-voltage main power transformer is to perform voltage conversion. It reduces the high voltage in the power system to the voltage level required by the user. By changing the turn ratio of the primary side (high-voltage side) and secondary side (low-voltage side) coils, voltage rise and fall can be achieved.
• Impedance matching: Transformers can also play a role in impedance matching. For different loads, their impedance values also vary. Through the transformer’s voltage transformation effect, the impedance of the load can be matched with the impedance of the power supply system, thereby ensuring stable current transmission.
• Voltage regulation: By changing the number of turns of the primary side coil or the number of turns of the secondary side coil, the output voltage can be adjusted. In the power system, transformers are used to achieve segmented voltage control to meet the electricity needs of different users and equipment.
• Filtering function: Some particular types of high-voltage main power transformers also have a filtering function, which can filter out harmonics and reactive power components in the power supply and improve the quality of the power supply.

5 FAQs of 20KV High Voltage Transformer Oil Immersed Power Transformer 100KVA-8000KVA Three Phase 380V Output

Here are key questions about our 20KV Oil-Immersed Power Transformers (100KVA-8000KVA, 3-Phase, 380V Output):

How much space does this transformer need?
Installation space varies significantly. Small units (100KVA-500KVA) fit tighter spots. Larger units (2500KVA-8000KVA) need substantial room. Always check the specific dimensions and clearance requirements in the manual before finalizing your site plan. Adequate airflow around the unit is critical.

Why is the transformer filled with oil?
The oil serves two vital jobs. It cools the transformer’s internal parts efficiently during operation. It also provides excellent electrical insulation. This prevents dangerous short circuits between high-voltage components. The oil keeps everything running safely and lasts long.

What size transformer do I actually need?
Choose based on your total electrical load. Calculate the combined power demand (in KVA) of all equipment it will supply. Add a safety margin, typically 15-20%. Avoid selecting a unit much larger than necessary. Oversized units waste energy and cost more upfront. Undersized units overload and fail. Our team helps determine the right capacity.

Are these transformers noisy?
They produce a constant humming sound. This is normal operation. Modern designs focus on minimizing this noise. Units are quieter than you’d expect. The actual noise level depends on the unit’s size and load. Review the sound pressure level (dB) specifications for the model you choose. Consider placement away from quiet zones.

What maintenance is required?
Regular checks are essential for long life and safety. Monitor the oil level consistently. Test the oil quality periodically for breakdown or contamination. Visually inspect for leaks, damage, or debris around the tank and bushings. Keep the exterior clean. Follow the detailed maintenance schedule provided. This prevents unexpected failures.
