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]
