10kV Oil Immersed Distribution transformer energy efficiency grade table

Oil-immersed transformer is a common power equipment. Its important parameters and related interpretations are as follows:

Rated capacity (kVA or MVA)

• Refers to the maximum power that the transformer can output when it is continuously running at rated voltage and rated current.
• For example, a 1000kVA transformer means that it can output 1000kVA of power under rated conditions.

Rated voltage (kV)

• The rated voltage value of the primary and secondary sides of the transformer. For example, a 10kV/0.4kV transformer means that the primary voltage is 10kV and the secondary voltage is 0.4kV.

Rated current (A)

• The maximum current allowed to pass through the transformer for a long time at rated capacity.

Winding connection group

• Indicates the connection method of the transformer winding, such as star (Y) or triangle (Δ). For example, Y, yn0 means that the high-voltage side is star-connected, the low-voltage side is star-connected and the neutral point is grounded.

Impedance voltage (%)

• When the secondary winding of the transformer is short-circuited and the primary winding is voltaged so that the current of the secondary winding reaches the rated value, the percentage of the voltage applied on the primary side to the rated voltage. The smaller the impedance voltage, the greater the short-circuit current of the transformer, and the higher the requirement for system stability.

No-load current (%)

• When the transformer is running at no-load at rated voltage, the current passing through the primary winding is usually expressed as a percentage of the rated current.

No-load loss (kW)

• The active power consumed by the transformer due to core hysteresis and eddy current loss when it is no-load.

Load loss (kW)

• The active power consumed by the winding due to resistance loss when the transformer is under rated load.
• Insulation and cooling parameters
