Development of Automated distribution system 1

The distribution system is vastly spread in the present age with the primary circuit starting from a sub-station and ending at the customer’s home. At this moment it is known to be the secondary service.

The voltage being received by the customer is of low voltage than that starting from the sub-station as it is divided to many customers along the way.

The voltage being utilized falls within the range of 2300- 35000 volts with huge dependence on the distance it has to cover, the amount of load and the utility standard practice. This makes the voltage distribution most suitable to less far areas.

The voltage transmission is usually carried out at high voltage. The high voltage first enters a transformer which is placed in a sub-station; the voltage gets reduced and after that distributed to various locations. Overhead pole lines or underground networking both ways can be utilized for the placement of conductors to be used during distribution.

3-montage-cuivre-packshotFor more than 30 years, electrical equipment manufacturers have developed some very attractive busbar and distribution systems (standard busbar profiles & sizes, busbar supports, comb busbar, distribution systems & accessories) to distribute power inside these electrical equipments in an easy and safe way, especially when they are type-tested.
As far as I see it a lot of panel builder use partially or totally these busbar systems

When professionals want to manage an electrical system in a new installation or after retrofit or extension of an existing installation, it is important to consider the Harmonic currents emitted by the non linear loads connected to the distribution system.
The non linear loads or products producing harmonics can be as example, for industrial equipments: welding machines, battery chargers, variable speed drives for electrical motors, uninterruptible power supplies, or for office equipments or household appliances: TV sets, fluorescent lighting, light dimmers, etc…
