Automatic Voltage Regulation with On-Load Tap Changer

The 10,000 kVA three-phase oil-immersed automatic voltage regulating transformers is equipped with an on-load automatic voltage regulation system, allowing the output voltage to be adjusted while the transformer remains energized.

The 14-position tap configuration provides multiple voltage adjustment points across the specified input voltage range. This design can help maintain a more stable output voltage when the supply-side voltage changes during normal power system operation.

The automatic regulation function is particularly useful for power networks where voltage fluctuations may occur due to changes in load, transmission conditions or grid operating conditions.

Copper Winding for High-Capacity Applications

The transformer uses copper windings for both electrical performance and mechanical reliability.

Copper provides good electrical conductivity and is widely used in high-capacity power transformers. For a 10,000 kVA transformer, the winding system is designed to handle the required operating current while maintaining the electrical and mechanical characteristics specified for the project.

The winding design is manufactured according to the specified voltage, capacity, connection configuration and performance requirements.

Ya0 Connection Symbol

The transformer uses a Ya0 connection symbol, defining the specified winding connection and phase displacement characteristics of the transformer.

The connection configuration is selected according to the requirements of the power system and can be confirmed during technical design and project engineering.
