(3) 131H to 136 Demand detection setting
The following operation method is setting.
Demand current, action of demand active power, high-alarm value, time interval, power factor, demand active
power.
◆ 131H Demand current upper limit. 133H Demand active power upper limit.
Set the high-alarm value of demand current(DA) and demand active power(DW).
The setting range is 5 to 100% (1% step). Selection by + and - , set value is updated by SET .
Default setting:80% (Demand current) , OFF [Non use] (Demand active power)
◆ 132 Demand current time interval. 134 Demand active power time interval.
Set the time interval (95% time interval) of demand current(DA) and
demand active power(DW). Selection by + and - , set value is updated
by SET .
Default setting:0 second (Demand current, Demand active power)
◆ 135 Demand active power operation method
The operating system of demand (DW) can be selected from d
(operating system according with bimetallic type:demand)
and A (Averaging arithmetic in demand time delay:average).
Selection by + and - , set value is updated by SET .
Default setting:d (Operating system according with
bimetallic type)
● Demand time delay characteristic (Demand current, Demand active power)
Arithmetic method
Demand current measurement :Arithmetic method according with bimetallic type.
Demand active power measurement:Arithmetic method according with bimetallic type (Default value).
Or the averaging arithmetic in a demand time interval.
One is selected by setting.
100% indication time is about 3 times the time delay at the case of the arithmetic method according with
bimetallic type.(In case of 10 minutes/95% of time interval, time to reach to 100% is about 30 minutes.)
Demand measurement is measured to the 2 times of the rated current, and the 2 times of a rated active power.
