• 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 High Voltage Main Power Transformer 400kv 500kv 750kv 120mva 100mva 200mva 120 250 200 315 500 1000 Mva Power Transformer

What voltage levels do these transformers handle?
These transformers manage high voltage electricity transmission. They work at 400kV, 500kV, and 750kV levels. These levels move power efficiently over long distances. They connect major substations and power plants.

What power capacities are available?
We offer a wide range of capacities. Common ratings include 100MVA, 120MVA, 200MVA, 250MVA, 315MVA, 500MVA, and 1000MVA. You choose the capacity matching your specific grid load requirements. Higher MVA handles more power flow.

How are these large transformers cooled?
Effective cooling is vital. Most use oil-immersed cooling systems. ONAN (Oil Natural Air Natural) is common for smaller units. Larger units often need ONAF (Oil Natural Air Forced) or OFAF (Oil Forced Air Forced). Fans force air over radiators. This keeps the transformer working safely even under heavy load. The oil gets hot. The cooling system removes this heat.
