HONDA QUALITY STANDARDS - SCOPE AND PURPOSE

Scope; this standard defines, describes and specifies the point of delivery to the network user, the main features of the voltage supplied by a global network of low voltage distribution and medium voltage under normal operating conditions. This standard describes the limits or values ​​to be expected to remain the constant voltage across the general distribution network and does not describe the typical situation is usually an individual user on the network.

This European Standard does not apply to abnormal operating situations, including the following:

- Temporary conditions designed to maintain power supply to network users after a failure or during maintenance work or construction on the network, or to limit the extent and duration of a power interruption;
- In case of non-compliance of the facility or equipment of a network user to the applicable rules or technical requirements of connecting, established, either by administration or by the operator of the distribution network, including the limits emission of conducted disturbances;

- Exceptional circumstances, in particular:
• exceptional weather conditions and other natural disasters;
• interference from third parties;
• decisions of public authorities;
• strikes (subject to legal requirements);
• force majeure;
• interruptions due to external causes.

The voltage characteristics given in this standard are not intended to be used as levels of support
(EMC) or emission limits of conducted disturbances user for general networks
of distribution.

The voltage characteristics given in this standard are not intended to be used to specify the requirements
teams in product standards and facilities.

This rule can be replaced in whole or in part by the terms of a contract between a user
individual network operator and distribution network.

Object

The purpose of this European standard is to define and describe the characteristics of the supply voltage supplied,
such as:
- The frequency;
- Size;
- The waveform;
- The symmetry of the line voltages.

These features are subject to change during the normal operation of a power system due to load changes, disturbances emitted by certain equipment, and the occurrence of faults due mainly to external causes.
Features vary randomly in time with reference to a given supply point, and randomly in space, with reference to a given instant. Because of these variations, the levels of the characteristics may be exceeded once.
Certain phenomena which have an impact on blood are particularly unpredictable which makes it very difficult to give useful values ​​corresponding definitive. The values ​​given in this standard for these phenomena, such as voltage sags and voltage interruptions are to be interpreted accordingly.
