Wireless secondary voltage drop tester will be defined as a new electric energy measurement to be bestowed favor on newly
Voltage transformer is an important part of electric energy metering device, and its secondary voltage drop is one of the main factors influencing the accuracy of the electrical energy metering device, so the voltage transformer secondary voltage drop tester will be defined as the electrical energy measurement to be bestowed favor on newly, the electrical energy metering device is one of important test equipment in the inspection work.
Previously, secondary voltage drop measurement is implemented by means of cable. But when this way of measurement is adopted, needs from the voltage transformer (PT) to the watt-hour meter place temporary laid a few meters to several hundred meters from the secondary cable, the cable sometimes also need to bypass the barriers, operation risk, time-consuming, very inconvenient. As a result, the manufacture and use of voltage transformer secondary voltage drop of wireless measuring instrument has been coveted by manufacturers and users.
Recently, by electronic and computer measurement and control instruments and systems suppliers, dongguan KEPIN quality measuring instrument equipment co., LTD. Department of science and technology research project of Shanxi Province "voltage transformer secondary voltage drop tester wireless" through organized by Shanxi Province department of scientific and technological achievements appraisal, the experts agreed that the products reach the international leading level. KEPIN instrument developed by using its own technology and unique algorithm "voltage transformer secondary voltage drop tester wireless" well balanced security convenient, measurement accuracy and ease of use. Contrast and Angle difference measurement precision has reached the level 1. Wireless secondary voltage drop tester at the same time, has strong ability of antijamming ability and long distance communication in 500 kv substation and large power plants are completed well measurements. The project won the "2009 taiyuan outstanding project of science and technology first prize" and other honors.
"Voltage transformer secondary voltage drop tester" wireless project is in dongguan KEPIN quality testing instruments and equipment co., LTD., under the leadership of general manager and technical director liu hua. Liu hua for years has been dedicated to digital power frequency electric quantity measurement technology research and development and technical management work, factory power frequency of the digital measurement algorithm has a very in-depth research, proficient in high-performance phase-locked frequency synthesizer and high-precision energy metering standard complex electronic scientific instruments, such as the development of the design. Especially for electric energy metering device error detection theory, methods and instrumentation design pioneering outstanding contribution.
Liu hua for electric power industry as the host grinds the user independently developed a series of innovative products, among them, the "field tester AP2003 electric energy measurement device" for the international initiative, has listed in the national key new product plan, small and mid-sized enterprise technology innovation fund projects, national torch plan, the torch plan, technological innovation in Shanxi Province, Shanxi Province taiyuan, key projects and major innovation project "double tenth project" and other kinds of science and technology plan.
Liu hua has a strong innovation consciousness, the research achievement has won the ministry, department of Shanxi Province and Shanxi Province economic commission, north China electric power station, electric power company, taiyuan city, Shanxi Province science and technology bureau, sichuan province issued a variety of awards and published many essays in domestic and international professional journals, he participated in drafting the national standards for the electronic watt-hour meter communication standard, is the international standard of the power supply system of power quality monitoring equipment, domestic tracked members of the working party, also served as the director of China branch of the embedded system software association, senior member of China instrument association, China director of the institute of measurement and other social functions. Cao Rui research and development of scientific and technological achievements has 15 patents, registration of copyright in computer software products more than 20.
