◆ 141H Zero-phase voltage upper limit
The upper limit of zero-phase voltage is setting.
Setting range. 5 to 150％(1％ step) and OFF(Non use).
Selection by ＋ and － , set value is updated by SET .
Default setting：5280V
◆ 142 Response time
The response time (90% response) of zero-phase voltage is setting.
Selection by ＋ and － , set value is updated by SET .
Default setting：0.1 seconds <秒>
◆ 143 Ground fault phase detection display automatic change
Set the whether it changes from a measurement display (an instantaneous
measurement display, the maximum, and the minimum measurement display)
to a ground fault phase detection display automatically at the case of
ground fault phase occurrence.
Selection by ＋ and － , set value is updated by SET .
Default setting：OFF (Not change)
<Caution> In addition to this setting, the display can be switched to
the ground fault detection display by a switch operation.
Please refer to "4.3.3 Ground fault phase detection display
change" about switch operation.
