Industrial EMC - A practical aproach
Learn how to counteract EMC disturbances in modern power grids.
EMC disturbances have increased significantly in recent years. Our old power grids cannot cope with today’s technology. This means that new design approaches and installation methods are required..
Description
As technology advances faster and faster in our grid-connected loads, the incidence of various types of grid disturbances that we were previously spared from is increasing. EMC disturbances, for example, have increased significantly.
A contributing factor to these disturbances is that the industry practice we rely on is outdated and no longer relevant for this type of load. The increased proportion of switched loads requires us to adapt our design methods and installation methods.
Many of our standards are outdated, and they offer no real support for the design of modern grids. In addition, for certain frequency ranges there is a complete lack of relevant standards.
Today’s discussions about “Smart Grid” also place new demands on how we build our grids. And today’s energy prices should have a major impact on how we handle losses when dimensioning.
So we should build robust grids for the future that minimize the disturbances that the loads can create and/or are exposed to. But to succeed in this, a holistic view of grids and loads is required.

Course Objective
The aim of the course is to provide participants with a fundamental understanding of how to build modern power grids with a high level of immunity to various Power Quality and EMC disturbances.
The course includes a range of calculation exercises for basic dimensioning of local power grids as well as industrial networks. Some exercises make use of the NETKOLL calculation software, and DranView is used to analyze measurement results.
A review is also provided of relevant standards, including their strengths and weaknesses. Here, particular emphasis is placed on the importance of clearly defined requirements from the client regarding losses and disturbance levels. Planning levels and EMC plans are the tools we use to specify these requirements.
Several examples of different types of disturbances are presented and explained.
The installation of modern loads places significant knowledge demands not only on installers but also on the inspectors responsible for approving the completed installation.
