12 Conclusion
History
Explores the parameters of dc power distributions within the scope of EN 300 132-2 that significantly contribute to the energy contained by a transient, discusses ways in which the transient can be controlled to reduce its harmful effects, and suggests ways in which the immunity of an electronic unit or a substantial telecommunications installation might be tested.
