: With two-system alarm
O: With alarm X: Without alarm
• This function is available when output terminal function setting is selected as an alarm
after the setting of alarm parameter setting and alarm output setting.
• Alarm judgment implements the OR operation in phases (when the value of a phase
exceeds the over voltage alarm threshold). In addition, release of an alarm implements the
AND operation (when the values of all phases are lower than over voltage alarm threshold
and voltage alarm hysteresis).
• Over voltage alarm threshold
:
0.0 to 12100.0 V (Initial value: 528.0 V)
• Over voltage alarm hysteresis
:
0.0 to 2200.0 V
(Initial value: 24.0 V)
• Over voltage alarm on-delay
:
0.1 to 10.0 s
(Initial value: 0.1 s)

: With two-system alarm
O: With alarm X: Without alarm
• This function is available when output terminal function setting is selected as an alarm
after the setting of alarm parameter setting and alarm output setting.
• Power factor alarm threshold
:-1.00 to 1.00
(Initial value: 0.00)
• Power factor alarm hysteresis
: 0.00 to 1.00
(Initial value: 0.05)
• Power factor alarm on-delay
: 0.5 to 10.0 s
(Initial value: 0.5 s)
*1. CTD8E (CT expansion) can perform the two-system setting only when it is connected to
PMU2A (power two-system).
