Reference Voltage
This reference voltage is referred as the reference voltage value for Dip[Sag]/Swell detection. Reference
voltage should be primary voltage value, does not have to be the same value with the rating voltage and the
value that is the real reference may be input. In case of 3P4W or 1P3W setup, primary line-to-line voltage or
line-to-neutral voltage can be selectively input.
Setup range Description
VL-L / VL-N 1 Primary line-to-line voltage or line-to-neutral
[d][d][d][d][d][d]
2
000001 ~ 999999
1. It can be selected only for 3P4W and 1P3W connection, but it is fixed to line-to-line voltage in other connection.
2. d  decimal number.
2. The connection reference scale for each voltage connection is as follows.
In each voltage connection, the reference voltage is determined as follows.
Voltage Connection Setup Type Description
3-phase 4-wire[3P4W] Line-to-line voltage setup Line-to-neutral reference voltage
=
1 √3
⁄
* Line-to-line voltage setup value
Line-to-neutral voltage setup Line-to-neutral reference voltage
= 1* Line-to-neutral voltage setup value
3-phase 3-wire[3P3W] Line-to-line voltage setup Line-to-line reference voltage
= 1* Line-to-line voltage setup value
1-phase 3-wire[1P3W] Line-to-line voltage setup Line-to-neutral reference voltage
=
1 2
⁄
* Line-to-line voltage setup value
Line-to-neutral voltage setup Line-to-neutral reference voltage
= 1* Line-to-neutral voltage setup value
1-phase 2-wire[1P2W] Line-to-neutral voltage setup Line-to-neutral reference voltage
= 1* Line-to-neutral voltage setup value
Demand Sub-interval
Accura 2300 uses sliding window demand power calculation method.
Demand time[minute]= Demand sub-interval x Number of demand sub-interval
ex] For the case with 15-minute demand time, demand sub-interval is 15-minute and number of demand sub-
interval is 1. Refer to “Chapter 5>Demand Measurement” for details.
Setup range Description
1 - 60 minutes[default 15] Demand sub-interval time
