This procedure is the first release. DC voltage transformer verification procedures 1 Scope This procedure is applicable to the first verification, subsequent verification and use of DC voltage transformers for HVDC transmission systems. an examination. 2 reference files This procedure refers to the following documents. GB/T 16927.1-2011 High voltage test techniques - Part 1. General definitions and test requirements GB/T 20840.7-2007 Transformers - Part 7. Electronic voltage transformers GB/T 26217-2010 DC voltage measuring device for HVDC transmission system For dated references, only the dated version applies to this Code; any undated quotation The latest version (including all amendments) applies to this procedure. 3 terms GB/T 20840.7-2007, GB/T 26217-2010 defined and the following terms and definitions apply to this procedure. 3.1 DC voltage transformer DCvoltagetransformer Also known as DC voltage measuring device. Means for providing a signal corresponding to the primary circuit DC voltage, for supply measurement Instruments, meters and protection or control equipment. [Refer to GB/T 26217-2010, 3.2] 3.2 primary voltage sensor primaryvoltagesensor An electrical, electronic, optical, or other device that produces a signal corresponding to a voltage between primary voltage terminals, The resulting signal is transmitted to the secondary device either directly or via a primary converter. [Refer to GB/T 20840.7-2007, 2.1.40] 3.3 primary converter primaryconverter A device that converts signals from one or more primary voltage sensors into signals suitable for the transmission system. [Refer to GB/T 20840.7-2007, 2.1.41] 3.4 Transmission system transmissionsystem A short or long range coupling device that transmits signals between primary and secondary components. According to the technology used, The transmission system can also be used to transmit power. [GB/T 20840.7-2007, 2.1.43] 3.5 secondary converter secondaryconverter Converting the signal transmitted by the transmission system to an amount proportional to the voltage between the primary terminals and providing it to the measuring instrument, Instrumentation and relay protection or control device. [Refer to GB/T 20840.7-2007, 2.1.44] ......
