We know that a good discrimination study allows the coordination of different protections at different levels of the installation, to guarantee the continuity of supply in the critical installations, in case of failure short circuits and overloads. What is a discrimination selectivity study? Discrimination selectivity is the selection of protective devices — so that the device nearest to a fault will trip rather than any device further ahead of it.
This is due to the system being coordinated to discriminate between incoming and outgoing devices and prevent any further outgoing fault current from affecting the entire system. Electrical engineers are often produce a discrimination selectivity study at various stages within a project.
The main point of the discrimination study is to demonstrate that:. Partial discrimination: selectivity is partial if the above condition is not fulfilled up to the bolted short-circuit current but only up to a lower value. This value is referred to as the selectivity limit. Total discrimination: for all fault values from overload to bolted short-circuits, distribution is totally selective if only the circuit breaker immediately upstream located above the fault opens.
Why a discrimination selectivity study? Carrying out a discrimination study is critical to ensure the correct functioning of the electrical system in the event of possible faults. To guarantee project design calculation, quality, safety and power supply, companies must comply with strict design rules. Domestic-type circuit-breakers must comply with IEC standard , or an equivalent national standard.
Defines the behaviour of a circuit breaker in relation to AC. The standard states that the top-rated current is A, while the lowest is 6A and maximum value of rated short-circuit capacity Icn is 25kA. These basic tech specifications tell us how different the use of circuit breakers defined by our two standards are.
Industrial circuit-breakers must comply with IEC and or other equivalent standards. They protect electrical power distribution of up to volts AC and volts DC with whole spectrum of rated current from 0,5 to A.
It is an especially important point for high-powered equipment, since this is generally located at the head of the installation and therefore has even greater consequences in the event of false tripping. All these factors are vital within the sector for energy production, energy transformation or energy distribution.
That is why the correct type of discrimination study is essential. For each type of fault there is a specific protective device protection against overload, short-circuit or earth fault currents, or against loss of voltage, etc. Each of these faults can cause a loss of discrimination if coordination of the protective devices has not been considered.

The reality of the Building Information Modelling BIM has become a necessary tool in the building industry and Trace-Software is at the leading-edge by combining electrical calculation and sizing with BIM.
The architecture, engineering, and construction AEC industry has always pursued techniques to reduce-costs of projects while at the same time, increase-productivity , quality, and reduce-delivery -time. The building information modelling BIM has increased in use over the last 6 years as an innovative way to design and manage projects. By adopting BIM, it can improve building performance and operations due to its collaborative approach. As the use of BIM globally grows, collaboration within project teams will also increase, which will lead to improved profitability, reduced costs and better management of time.
BIM simulates the construction project in a virtual setting. With BIM technology, an accurate model of a building, known as a building information model, is digitally produced. The building information model contains precise geometry and relevant data needed to support the design, procurement, fabrication, and construction activities required to realize the building.
A building information model characterizes the geometry, spatial relationships, geographic-information, quantities and properties of building elements, cost estimates, material inventories, and project schedule. The concept of BIM and its implementation is quickly becoming compulsory on all centrally procured public sector and private sector projects in many countries around the world. The USA was perhaps one of the first countries to adopt the use of BIM and has taken significant steps in this regard.
Below are some of the countries already using or aiming to implement BIM standards. The way of designing the construction of buildings is changing with the utilisation of BIM.
It is now becoming a legal standard for most countries and those not using it are working towards using it. There are potential risks associated with BIM that can be separated into two broad categories: legal or contractual and technical.
The need to protect BIM-data through copyright laws and other channels can cause issues if it is not property set-out. This will help assist stakeholders define the model management, frameworks and ensure traceability. The technology to implement BIM is available and rapidly growing, ensuring the growth of the concept. With a standardisation of Levels and more and more countries adhering to the standard, BIM is here to stay.
BIM is the digital revolution within the construction world. A revolution ready to disrupt the industry, automate and revolutionize it, as well as bringing significant saving in time and costs and quality.
The Building Information Model — the digital description of each aspect of the building process, is one of the key elemental outputs of the process, aimed to create a more efficient construction sector.
The concept of BIM and its practicalities have been taken up at different rates by different countries and different professional levels. At this stage of the BIM official implementation is fundamental to create a principle framework.
BIM is not something new, it existed for a long time even if many countries are just starting to consider it now driven by several economic and environmental factors.

This a module that integrates calculation software in BIM with the following iterative processes: Facilitating the flow between a 3D model and the electrical sizing and calculation that all meet the IFC format standards. Based on this information, the full life-cycle of a building, from initial conception to project completion, can be managed effectively. BIM refers to a collaborative method of working which is based on the generation and exchange of data between various project parties on the same project.
It provides a powerful way to access the BIM objects and stay current with this growing trend in construction design. Architecture, engineering, and construction AEC , for a long time these industries have sought out to increase productivity and quality, while at the same time decrease costs as well as project delivery time, hence using BIM gives the best potential in reaching these goals. BIM simulates the construction project in a virtual environment. The key benefit of a BIM is its accurate geometrical representation of the parts of a building, in an integrated data environment.
The BIM maturity model describes levels of maturity with regards to the ability of the construction supply chain to operate and exchange information. The BIM model levels are applied to the entirety of the project scenario however a company may claim to operate at Level 2 but, can only operate at Level 1 which is very normal as companies or organisation mature on different timescales.
