Fault record – measurement indication
This item can only be displayed when fault record data has been stored. The item data will not be shown when there is
no record data.

Description
1
The indication mode starts.
2
When this switch is kept depressed until
the item number "211" appears, the
A-phase current in the first phenomena
will be indicated.
Ex. : A-phase current: 0.9 kA
3
The B-phase current in the first
phenomena will be indicated.
Ex. : B-phase current: 0.9 kA.
4
The C-phase current in the first
phenomena will be indicated.
Ex. : C-phase current: 0 A
5
The zero-phase current in the first
phenomena will be indicated.
Ex. : Zero-phase current: 0 A
6
Changing the item number to "212" will
display the A-phase current in the second
phenomena.
Ex. : A-phase current: 0 A
7
The B-phase current in the second
phenomena will be indicated.
Ex. : B-phase current: 1.8 kA.
Where the following system fault currents have been recorded:
: A-phase = 0.9 kA, B-phase = 0.9 kA, C-phase = 0 A, Zero-phase = 0 A
: A-phase = 0 A, B-phase = 1.8 kA, C-phase = 1.8 kA, Zero-phase = 0 A
: No records
