7.5.4 Voltage ratio setting refers to current ratio setting
For example: If the current input is connected by external CT and the rated value is 40A/5A, set the rated value of primary side
current to 40A, the scale value to 1, and the rated value of secondary current to 5A. Neutral current setting is the same. If the voltage
input is connected by external PT and the rated value is: 6000V/400V, then set the rated value of the primary voltage to 6000V, the
scale value to 1, and the rated value of secondary voltage to 400V.
7.5.5 Pulse constant setting (Only APM801 can be set)
When the pulse constant is set to 0, the default is 8000 when the rated value of the secondary side current is 1A, and the default
is 4000 when the rated value of the secondary side current is 5A. When the pulse constant is set to non-zero, the actual pulse constant
is the setted value*100. For example, if the set value is 50, the actual pulse constant is 5000.
Note:
①
The primary value must be greater than or equal to the secondary value.
② Only the APM801 can set the pulse constant.
7.5.6 Alarm Settings
1. Press ◀▶ until ALM is selected and and press the Enter key.
2. Press
◀▶
key to select the alarm group (a total of two groups of alarms) and press the Enter key.
