Delay: 2.00sec Allow for dielectric storage in the panel
End On: FAIL As required
Lim: 100.0M-no max As required
ARC DETECT:OFF As required
DISCHARGE: NONE No need to discharge before the next step, reduces test time
ON FAIL: ABORT SEQ Optional, could continue testing if fails
Seq 1 Step 2 DCW Different breakdown and leakage limits, so use DCW
LEVEL: 2500.0V As required
BREAKDOWN: 20.00mApk Must be greater than the charging current
RAMP: 1.00sec As required
DWELL: 5.00sec As required
Delay: 1.00sec Allow for dielectric storage in the panel
Lim: 0n-1.000mA As required
ARC DETECT:OFF As required
DISCHARGE: FAST
ON FAIL: ABORT SEQ
Example 4 –
In example 3 above, it is required to ensure that the panel is connected to the 95x during the tests. Since the panel
has very little DC leakage but has significant capacitance, this is easily achieved by adding a low voltage AC test at
the start of the sequence. Since the load has a minimum capacitance of 1uF and a maximum of 4uF, the current at
10V/20Hz will be between 1.25 and 5mArms. This requires that the Opt.AC-2 option be installed.
This is accomplished in three steps as follows –
Seq 1 Step 1 ACez Simple RMS min and breakdown, so use ACez
LEVEL: 10.0V 20.0Hz As required
RAMP: 0.02sec Use a fast time to reduce test time
DWELL: 0.10sec Use a fast time to reduce test time
Lim: 1.000m-5.000mA As required
ON FAIL: ABORT SEQ No need for further tests if fails
Seq 1 Step 2 DCIR This could also be a DCW test with the same results
LEVEL: 500.0V As required
BREAKDOWN: 5.000mApk Must be greater than the charging current
RAMP: 1.00sec As required
DWELL: 5.00sec As required
Delay: 2.00sec Allow for dielectric storage in the panel
End On: FAIL As required
Lim: 100.0M-no max As required
ARC DETECT:OFF As required
DISCHARGE: NONE No need to discharge before the next step, reduces test time
ON FAIL: ABORT SEQ Optional, could continue testing if fails
Seq 1 Step 3 DCW Different breakdown and leakage limits, so use DCW
LEVEL: 2500.0V As required
BREAKDOWN: 20.00mApk Must be greater than the charging current
RAMP: 1.00sec As required
DWELL: 5.00sec As required
