t1 * Duration of first current flow. The specified
accuracy limit must not be reached within time t
al1
.
Only displayed if parameter "Spec." is "by Duty"
and "Duty" is "C-O-C-O".
Possible values: 0.000 to 5.000s or soft key
100ms.
Default: ? or ?*.
* If displayed, this parameter is relevant for
assessment. No automatic assessment is
available if the user did not enter data for this
parameter prior to the test.

tfr * Dead time between first opening and reclosure.
Only displayed if parameter "Spec." is "by Duty"
and "Duty" is "C-O-C-O".
Possible values: 0.00 to 5.00s or soft key 300ms.
Default: ? or ?*.
* If displayed, this parameter is relevant for
assessment. No automatic assessment is

t-al2 * Permissible time to accuracy limit for second
energizing period of the duty cycle.
Only displayed if parameter "Spec." is "by Duty"
and "Duty" is "C-O-C-O".
Possible values: 0.000 to 5.000s or soft key 40ms.
Default: ? or ?*.
* If displayed, this parameter is relevant for
assessment. No automatic assessment is
available if the user did not enter data for this

1. If the question mark is entered for this parameter and a new test is started, CT Analyzer automatically tries to determine the
value using its integrated guesser function (see chapter 9 on page 138).
2. If the question mark is entered, half the voltage entered or measured for E
k
is used.
3. If the question mark is entered, CT Analyzer uses the excitation current measured at the voltage value defined at E
1
. In this
case, the assessment for this parameter is OK.
