ANSI 32 Reverse Power Threshold
(%)
The percentage of nominal power that determines when the
Reverse Power Alarm status is set (after the Reverse Power
Delay). Nominal Power = Nominal Voltage x Nominal Current.
For Grid 1, the Reverse Power alarm will be triggered if a
circuit’s active power exceeds the Reverse Power Threshold for
a time period longer than Reverse Power Delay.
For Grid 2, the Reverse Power alarm will be triggered if a
circuit’s active power falls below the Reverse Power Threshold
for a time period longer than Reverse Power Delay.
Range: -100 to 99
Default: -10
ANSI 32 Reverse Power Delay
1
(sec)
The amount of time a grid must remain below the Reverse
Power Threshold before the Reverse Power Alarm status is set.
Range: 0.1 to 3276.7
Default: 10.0
ANSI 50 Over Current Threshold
(%)
The current above which the Over Current Alarm status is set
(after the Over Current Delay), as a percentage of the Nominal
Current parameter.
Range: 110 to 250
Default: 110
ANSI 50 Over Current Delay
1
(sec)
The amount of time a phase current must remain above the
Over Current Threshold before the Over Current Alarm status
is set.
Range: 0.1 to 3276.7
Default: 10.0
ANSI 59 Over Voltage Threshold
(%)
The phase voltage above which the Over Voltage Alarm status
is set (after the Over Voltage Delay), as a percentage of the
Nominal Voltage parameter.
Range: 101 to 250
Default: 115
ANSI 59 Over Voltage Delay
1
(sec)
The amount of time a phase voltage must remain above the
Over Voltage Threshold before the Over Voltage Alarm status
is set.
Range: 0.1 to 3276.7
Default: 10.0
1
For all alarm conditions, the clear time is the same as the set time. In order for the alarm to be cleared, the alarm condition must be
absent continuously for the entire Delay.
