Rated wattage (0,1 W precision

power rating of an arc furnace transformer

three-phase medium power transformers with a power rating below 5 kVA

This value defines the power which is consumed by an LED module.

Sr is the rated power of the transformer or autotransformer on which Pk is based

Efficiency Base ballast (EBb) means the relationship between the rated lamp power (Plamp) and the ballast efficiency.

The level of losses is given for the highest possible rated power and on the basis that the rated power is the same regardless of the combination of voltages.

Pcor is the rated power measured at nominal input voltage and corrected where appropriate in accordance with Table 1.

Where PLrated is the rated lamp power and ηballast is the minimum energy efficiency limit of the respective EEI class.

maximum available power on the lower voltage of the low-voltage winding limited to 0,85 of the rated power assigned to the low-voltage winding at its higher voltage.

the possibility to set out minimum values of the Peak Efficiency Index for all medium power transformers, including those with a rated power below 3150 kVA

maximum available power on the lower voltage of the high-voltage winding limited to 0,85 of the rated power assigned to the high-voltage winding at its higher voltage.

information on rated power, load loss and no-load loss and the electrical power of any cooling system required at no load

In this part of ISO 8528, "low-power" is taken to mean rated power of a magnitude up to approximately 10 kW/50 Hz, 12 kW/60 Hz.
