DD CLC/TS 50539-22:2010 Low-voltage surge protective devices. Surge protective devices for specific application including d.c. Selection and application principles. Wind turbine applications DD CLC/TS 50539-22 is a Technical Specification which applies to surge protection of wind turbine generators and wind power systems. Normative references are made to generic standards for lightning protection, low-voltage systems and high-voltage systems for machinery and installations and electromagnetic compatibility (EMC). DD CLC/TS 50539-22 defines requirements for selection and installation of surge protective devices for the power circuits. Some special information about particular testing are also included since there is not a current standard for testing surge protective devices for wind turbines. Contents of DD CLC/TS 50539-22: 1 Scope 2 Normative references 3 Terms and definitions 4 General 5 Equipment to be protected 6 Configuration of a typical wind turbine 7 Protection of power circuits within a wind turbine 7.1 Introduction 7.2 Protection of the generator alternator excitation circuit 7.3 Protection of the line side circuit of the generator 7.4 Protection of control power lines Annex A (informative) Typical values of vibration withstand of SPDs used in wind turbine systems Bibliography
