From the International Electrotechnical Commission webstore: "IEC 60143-2:2012 covers protective equipment for series capacitor banks with a size larger than 10 Mvar per phase. Protective equipment is defined as the main circuit apparatus and ancillary equipment, which are part of a series capacitor installation, but which are external to the capacitor part itself. The … [Read more...]

IEC 62488-1:2012 applies to the planning of analogue and digital power line carrier systems operating over EHV/HV/MV electricity grids. The object of this standard is to establish the planning of the services and performance parameters for the operational requirements to transmit and receive data efficiently over power networks. The transmission media used by the different … [Read more...]

From the International Electrotechnical Commission webstore: "This part of IEC 61557 specifies the general requirements for measuring and monitoring equipment for testing the electrical safety in low voltage distribution systems with nominal voltages up to 1 000 V a.c. and 1 500 V d.c. When the measuring of equipment or the measuring of installations involves measurement tasks … [Read more...]

IEC 62553:2012(E) is intended to establish measuring methods that enable the objective evaluation of the performance of transmission networks in order to make stable DTTB services a reality and establish a technical baseline. The measurement methods described are intended for digital terrestrial television transmission network test and validation. Learn more. … [Read more...]

IEC 61558-2-14:2013 deals with the safety of variable transformers for general applications and power supply units that incorporate variable transformers for general applications. Transformers incorporating electronic circuits are also covered by this standard. This first edition cancels and replaces the chapter IV of the IEC 60989 published in 1991 and includes an update of … [Read more...]
