        Energy Storage on LV Grids

        Planning, Installation and Operation of Battery Storage Systems

        by Marc Fengel

        To ensure availability in future decentralized energy generation and consumption, electrical energy storage systems are inevitable. They store electrical energy of generation plants (e.g. the photovoltaic system) when sun is shining and make energy available again at any time. That means that energy is consumed where it is generated, reducing grid losses and creating self-sufficiency. However, this also increases the complexity of systems. Which makes it more difficult for planners, installers and operators to construct such systems safely and in accordance with the recognized rules of technology, to integrate them into existing systems and to operate them safely. This book deals with the various storage concepts, taking into account the currently valid installation regulations. It serves as a guide for planners, installers and operators on the complex topic of storage systems. The following topics are included: Terms and definitions Application of technical regulations VDE-AR-E 2510-2 Operating modes Protective measures in electrical plants with storage Erection of generating plants Requirements for grid connection Installation of storage tanks Testing of storage tanks

        Compliant Installation of Photovoltaics

        by Heinz-Dieter Fröse

        The number of installed photovoltaic systems is constantly increasing; the trend is clearly upward. However, inspectors of these systems repeatedly find a large number of defects that impair the systems' functionality. Consequences are considerable damage during natural events or through many years of operation. This book provides installers with comprehensive information on: Preparatory measures for the installation of a photovoltaic system, Selection of products, Installation regulations, Electrotechnical installation guidelines, Regular inspections, Work safety, Important aspects of practical implementation, Electrotechnical testing and documentation of photovoltaic systems, and Maintenance of photovoltaic systems. The updated 4th edition taks all current standards, regulations and guidelines into account.

        Voice over IP

        An Introduction to Techniques with SIP

        by Thomas Wübbe

        Since the switch-off of classic telephony technology in 2019, the Session Initiation Protocol (SIP) dominates providers' telephony solutions. This book gives an introduction to this technology. It shows principles as well as the common architecture of Voice over IP with SIP. In addition to differences and changes to the "old" telephone technology, step-by-step methods and requirements for Voice over IP are discussed.Many protocol examples show how SIP works. They help troubleshooting when something does not work. A special practical chapter shows how to do analyses via Wireshark and explains logging in detail. These topics are included: Fundamentals of packet switching and standardization, Internet Protocol (IP) VoIP principle, Architecture of SIP SIP signaling Session Description Protocol (SDP) VoIP and NAT Quality of Service (QoS) Introduction to packet analysis with Wireshark, and Practical exercises.

        Emergency Lighting

        by Bruno Weis, Hans Finke

        Our reference book on emergency lighting! Focus is on the lighting and electrotechnical requirements for emergency and safety lighting. A large area is taken up by the diverse European and national standards, regulations, and laws.Due to the massive changes in emergency lighting since the previous edition (2017), the book has been completely revised. Extensive changes are made in particular by new possibilities and their implementation by LED technology, which today is used almost exclusively within. "Lighting Requirements" have also been completely revised. New aspects have also been added, such as assembly points, escape routes in outdoor areas, escape route marking for people with mobility impairments, and escape and rescue plans. All current standards, regulations and guidelines have been taken into account. This book covers  - which European and national requirements from product law, occupational health and safety, and building law must be observed, as well as which electrical and lighting engineering standards must be observed, - what the central principles and terms of lighting technology are and mean, - which lighting requirements apply, e.g. for escape and rescue routes, - which specifications apply to emergency lighting - how the specifications for emergency luminaires are to be correctly interpreted and implemented, - how optical safety guidance systems interact with emergency and safety lighting.

        Testing of Electrical Systems, Vol. 1

        Basics, Evaluation criteria, Protection goals

        by Marc Fengel

        Not all testing is the same. What DIN VDE 0100-600 means for installers of electrical systems, DIN VDE 0105-100 is for operators. But even beyond that, comprehensive and broad knowledge is required for testing electrical systems.Volume 1 provides inspectors, experts, consultants, planners and operators with an overview of the planning principles for electrical systems and the requirements for test personnel. It also deals with the legal principles of the german Energy Industry Act (EnWG), Product Safety Act (ProdSG) and Occupational Health and Safety Act (ArbSchG).

        Basics of Field Theory, Practice of Field Measurement Techniques

        by Martin H. Virnich

        The teaching of well-founded, practice-oriented EM field measurement technology on a scientific basis is the central concern of Dr.-Ing. Martin H. Virnich's book. In an easily understandable form and without "higher" mathematics, the author clearly presents the fundamentals of field theory in a depth necessary for practice. Core topics of his book are the following aspects: Physics of EM fields, Measurement of vector fields, Alternating electric fields (low frequency and DC fields), Alternating magnetic fields (low frequency and DC fields), Electromagnetic waves (high frequency), "Dirty Power", as well as The alteration of the natural EMF spectrum and its consequences. New to this 2nd edition is a detailed section on 5G NR, which deals with the current mobile communications standard and its many manifestations. In doing so, it dispels a number of myths surrounding 5G.

        KNX/EIB Engineering Tool Software

        Safe Installation and Changeover from ETS5 to ETS6

        by Michael Körmer, Willi Meyer

        Smart home solutions are in vogue, but require precise knowledge of the underlying hardware and software. Those who do not deal with ETS programming on a daily basis sometimes find it difficult. Instead of relying on memory and colleagues' knowledge for setup, this book helps as a step-by-step guide: the overall process of programming and commissioning KNX/EIB projects based on the current Engineering Tool Software (ETS) is covered. This enables you to follow all the necessary steps before, during and after processing with ETS5 and ETS6 "in one piece". The book takes into account the current state of the software based on ETS5 as well as ETS6. From the determination of requirements to the documentation, the necessary knowledge is conveyed. All actions with the discussed software tools are illustrated by screenshot, which ensures a good comprehensibility. For practical understanding, the complete project of a single-family house is also presented step-by-step and richly illustrated. This book will help you especially with the following questions: What are the basics of KNX hardware and software? What basic knowledge do I need specifically for ETS5 and ETS 6? What are the differences and similarities between the two KNX tools? How do I lead an extensive KNX project to success? (Practical example)
