Article 2 U.K. Definitions

[F1 The definitions set out in the Ecodesign for Energy-Related Products Regulations 2010 apply; and for any term that is not defined in those Regulations, the definitions set out in Directive 2009/125/EC of the European Parliament and of the Council of 21 October 2009 establishing a framework for the setting of ecodesign requirements for energy-related products, as it had effect immediately before IP completion day, apply. The following definitions also apply—]

(1)

‘Power transformer’ means a static piece of apparatus with two or more windings which, by electromagnetic induction, transforms a system of alternating voltage and current into another system of alternating voltage and current usually of different values and at the same frequency for the purpose of transmitting electrical power.

(2)

‘Small power transformer’ means a power transformer with a highest voltage for equipment not exceeding 1,1 kV.

(3)

[F2 ‘medium power transformer’ means a power transformer with all windings having rated power lower than or equal to 3 150 kVA, and highest voltage for equipment greater than 1,1 kV and lower than or equal to 36 kV.

(4)

‘Large power transformer’ means a power transformer with at least one winding having either rated power greater than 3 150 kVA or highest voltage for equipment greater than 36 kV.]

(5)

‘Liquid-immersed transformer’ means a power transformer in which the magnetic circuit and windings are immersed in liquid.

(6)

‘Dry-type transformer’ means a power transformer in which the magnetic circuit and windings are not immersed in an insulating liquid.

(7)

[F2 ‘Medium power pole-mounted transformer’ means a power transformer with a rated power of up to 400 kVA suitable for outdoor service and specifically designed to be mounted on the support structures of overhead power lines.]

(8)

‘Voltage Regulation Distribution Transformer’ means a medium power transformer equipped with additional components, inside or outside of the transformer tank, to automatically control the input or output voltage of the transformer for on-load voltage regulation purposes.

(9)

‘Winding’ refers to the assembly of turns forming an electrical circuit associated with one of the voltages assigned to the transformer.

(10)

‘Rated voltage of a winding’ (U_r) is the voltage assigned to be applied, or developed at no-load, between the terminals of an untapped winding, or of a tapped winding connected on the principal tapping.

(11)

‘High-voltage winding’ refers to the winding having the highest rated voltage.

(12)

‘Highest voltage for equipment’ (U_m) applicable to a transformer winding is the highest r.m.s phase-to-phase voltage in a three-phase system for which a transformer winding is designed in respect of its insulation.

(13)

‘Rated power’ (S_r) is a conventional value of apparent power assigned to a winding which, together with the rated voltage of the winding, determines its rated current.

(14)

‘Load loss’ (P_k) means the absorbed active power at rated frequency and reference temperature associated with a pair of windings when the rated current (tapping current) is flowing through the line terminal(s) of one of the windings and the terminals of the other windings are in short-circuit with any winding fitted with tappings connected to its principal tapping, while further windings, if existing, are open-circuited.

(15)

‘No load loss’ (P_o) means the active power absorbed at rated frequency when the transformer is energised and the secondary circuit is open. The applied voltage is the rated voltage, and if the energized winding is fitted with a tapping, it is connected to its principal tapping.

(16)

‘Peak Efficiency Index’ (PEI) means the maximum value of the ratio of the transmitted apparent power of a transformer minus the electrical losses to the transmitted apparent power of the transformer.

(17)

[F3 ‘Declared value(s)’ mean the values given in the technical documentation pursuant to [F4 paragraph 1(2)(b) of Schedule 1A to the Ecodesign for Energy-Related Products Regulations 2010], and where applicable, the values used to calculate these values.

(18)

‘Dual voltage transformer’ means a transformer with one or more windings with two voltages available in order to be able to operate and supply rated power at either of two different voltage values.

(19)

‘Witnessed testing’ means actively observing the physical testing of the product under investigation by another party, to draw conclusions on the validity of the test and the test results. This may include conclusions on the compliance of testing and calculations methods used with applicable standards and legislation.

(20)

‘Factory acceptance test’ means a test on an ordered product where the customer uses witnessed testing to verify the product’s full accordance with contractual requirements, before they are accepted or put into service.

(21)

‘Equivalent model’ means a model which has the same technical characteristics relevant for the technical information to be provided, but which is placed on the market or put into service by the same manufacturer or importer as another model with a different model identifier.

(22)

‘Model identifier’ means the code, usually alphanumeric, which distinguishes a specific product model from other models with the same trade mark or the same manufacturer’s or importer’s name.]
