"National Grid smart meters with components and technical specifications" series of standards started all preparation
June 27, China Electric Power Research Institute in Beijing organized a national grid company "smart meter components technical specifications" series of standards, "Part 7: Chip Capacitors" and "Part 15: Current Transformer " Technology Seminar At this point, the series of standards of technical specifications have all started to be prepared and released one after another. The "Smart Meter Technical Specifications" series of standards consists of 15 technical standards, including metrology chips, MCUs, LCDs, electrolytic capacitors, varistors, current transformers, crystal resonators, clock chips, diodes, resistors , Chip capacitors, optocouplers, primary batteries, load switches, RS-485 and so on. The establishment of series of standards to strengthen the energy meter components quality management, standardize component performance indicators and test methods, and effectively improve the reliability of the power meter to ensure accurate and reliable measurement of electric energy laid the foundation. At the meeting, China Electric Power Research Institute conducted a report on the first draft of two standards, and the participating experts conducted in-depth discussions on the standard reference documents, technical requirements, test methods and inspection rules. Part 1: Electrolytic Capacitors "," Part 2: Varistors "," Part 3: Resistors "and" Part 4: Optocouplers ", the series of technical specifications drafted by China Electric Power Research Institute Four technical standards were released in May 2014.
Industrial Drone difference as the entertrainment drones, It is for some application purpose. Such as Security Patrol Drone, Inspection Drone,Fire Extingurisher Drone ,Heavy payload Logistics Drone etc. Because these drones has different applications so they have different Drone Frame ,propulsion system, Drone Flight Controller and equipments. Usual long flight time, long distance control range request. Configration of Ground Control Station, Videolink Datalink, Zoom Camera, Gimbals etc.
