Standard Value
When you set active power and reactive power as alarm element, the setting range is determined by the
standard value calculated using the following calculation formula.
■
The standard value of active power/reactive power
Measuring element
Calculation method for standard value
Active power
VT ratio × CT ratio × Intrinsic power (100%) kW
Reactive power
Note1: When you set to
‘Without VT (Voltage direct input)’, the VT ratio is 1. For intrinsic power, refer to the following table.
Note2: The calculated value is round to the nearest number as the table in the next page.
