Introduction

Using knowledge about sources of interference and coupling mechanisms, we have the following possibilities to reduce electromagnetic effects:

• Take measures against sources of interference that reduce the transmission of disturbance

• Take measures to limit the spreading of disturbance

This chapter provides detailed descriptions about basic measures to take against sources of interference, and measures to lessen their expansion (coupling).

You will need the information given in this chapter to understand EMC measures in a system and for EMC compatible design, and also to understand installation procedures.

A prerequisite for this chapter is knowledge about the types of sources of interference, the superposition of interference and useful signals and about coupling mechanisms.
