6 Buffer memory
6.3.11 Multiplier of the electric voltage (Un \ G300)
The multiplier of the electric voltage is stored.
(1) Details of stored data
(a) Storage format
Data are stored as 16-bit signed binary in the buffer memory.
- Data range: -3 (fixed)
(b) Update timing
Because it is fixed at -3, there is no update.
6.3.12 1 - 2 line voltage (Un \ G302, 303), 2 - 3 line voltage (Un \ G304, 305), 3 - 1 line voltage (Un \ G306, 307)
The electric voltage between every combination of wires (effective value) is stored.
(1) Details of stored data
(a) Storage format
Data are stored as double-word 32-bit signed binary in the buffer memory.
- Data range: 0 to 99999900 (0 to 99,999.900 V)
*Restrictions for measured data including resolution and measuring range, refer to section 4.2.1.
(b) Unit
×10 -3 V *Unit is fixed.
(c) Update timing
It will be updated every measuring cycle (250 ms).
6.3.13 Average voltage (Un \ G314, 315)
Stores the Average voltage.
For procedure for storing the Average voltage using phase wire system, refer to 4.2.1 (2).
(1) Details of stored data
(a) Storage format
Data are stored as double-word 32-bit signed binary in the buffer memory.
