Definitions
For purposes of this document, the terms and definitions:

Network user:
Party that is supplied or supplies electricity to a distribution network.

Operation of the distribution network:
Party responsible for operating, ensuring the maintenance and, if necessary, the development of network
distribution in a given area, to ensure network capacity to meet long term demands reasonable
distribution of electricity.

Points of delivery:
Point in a distribution network so designated and fixed by contract, in which energy is exchanged
power between the parties that have signed the contract.
NOTE: This item may be different, for example, the measuring point or point of common connection.

Supply voltage:
RMS value of the voltage present at a given supply point, measured in a time interval
given.

Rated voltage (Un):
Voltage that designates or identifies a distribution network which refers to certain characteristics of
operation.

Declared voltage (Uc):
The declared voltage Uc is usually a nominal voltage distribution network. If, as
following an agreement between the operator of the distribution network and the network user, the supply voltage
applied across the terminals differs from the nominal, then the tension corresponds to the supply voltage
Uc declared.

Low Voltage (LV):
In the scope of this European standard nominal voltage whose rms maximum is 1 kV.

Medium Voltage (MV):
In the scope of this European standard voltage whose effective value of greater than 1 kV and less than 35 kV.

Normal Operation:
Conditions that may respond to the demand of the load and generation, network maneuvers and
elimination of faults with automatic protection systems in the absence of exceptional conditions due
external influence or force majeure.

Conducted Disturbance:
Electromagnetic phenomenon spread across the conductors of the lines of a distribution network. In some
cases, an electromagnetic phenomenon spreads through the windings of the transformers and, therefore, between networks of different voltage levels. These disturbances can degrade the performance of an appliance, equipment or system, or cause damage.

Frequency of the voltage supply:
Repetition rate of the fundamental component of the voltage measured during a time interval
given.

Variation of stress:
Increase or decrease in voltage, usually caused by load variations.

Rapidly varying voltage:
Variation of rms voltage maintained between two consecutive time intervals
defined but not specified (for details see EN 61000-3-3).

Voltage fluctuation:
Series of voltage variations, cyclic variation of the envelope of the stress.
[IEV 161-08-05].

Flicker (Flicker):
Impression of unsteadiness of visual sensation due to a light stimulus in which the brightness or
spectral distribution fluctuates over time. [IEV 161-08-13].

NOTE The voltage fluctuations cause variations in luminance of the lighting, which produces the phenomenon called blinking eye. Above a certain threshold, flicker becomes annoying. This discomfort increases rapidly with the amplitude of the fluctuation. For some repetition, even the weak amplitudes can be annoying.
