Section 5 BUFFER MEMORY
5.3.14 Maximum voltage (Un\G320, 321), minimum voltage (Un\G328, 329)
Stores the max./min. values of the voltage among in-between wires.
For procedure for storing the max./min. voltage using phase wire system, refer to "3.4.1(2)".
(1) Details of stored data
(a) Storage format
Data is stored as double-word 32-bit unsigned 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 "3.4.1".
(b) Unit
-3 V *Unit is fixed.
×10
(c) Update timing
It will be updated every measuring cycle if it exceeds the voltage max. value or goes under the voltage
min. value.
For measuring cycle, refer to "5.2.12".
5.3.15 Year of time of max. voltage (Un\G322),
month and day of time of max. voltage (Un\G323),
hour and minute of time of max. voltage (Un\G324),
second and day of the week of time of max. voltage (Un\G325),
millisecond of time of max. voltage (Un\G326),
year of time of min. voltage (Un\G330),
month and day of time of min. voltage (Un\G331),
hour and minute of time of min. voltage (Un\G332),
second and day of the week of time of min. voltage (Un\G333),
millisecond of time of min. voltage (Un\G334)
Stores year, month, day, hour, minute, second, day of the week and millisecond of time of maximum voltage
(Un\G320, 321) and minimum voltage (Un\G328, 329) were updated.
