During the revision process, the revision team has undertaken extensive investigations and studies, generalized the experiences from implementation of the code of the former edition and collected comments from interests concemed throughout the country and then reviewed and finalized the draft. This code is organized into ten chapters and three appendixes, mainly including: General, Terms and Symbols, Electrical Measuring Devices, Energy Metering, Electrical Measuring in DC Converter Stations, Computer Supervisory System Measurement, Electrical Measuring Transducers, Instrument Current Transformers and Voltage Transformers, Secondary Wiring for Measurement and Requirements on Instrument Installation.
