PCS100 AVC-40 Commissioning Checklist
1.9 External Transformer Wiring Check – No Load
This test only needs to be performed on the PCS100 AVC-40s constructed with separate Controller and
Transformer Enclosures. It is not necessary for small PCS100 AVC-40s with a single enclosure.
Note: This test will add up to 10% over-voltage at the output of the PCS100 AVC-40.
No
Description
64.
Set 20 Configuration Check Mode to "true" in the COMMISSIONING menu and Start
the PCS100 AVC-40. This will correct the output voltages V1 to 100%, V2 to 105% and
V3 to 110% of 13 Supply Voltage setting.
Note : V1 = V L1'L2', V2 = V L2'L3', V3 = V L3'L1'
65.
Scroll to the status page of the GDM and verify the displayed output voltage V1, V2
and V3 is within 1% of the values in step 62. This verifies the transformer is wired
correctly and ratios are correct.
Stop the PCS100 AVC-40 and then set 20 Configuration Check Mode back to "false".
66.
If the output voltages V1, V2 and V3 are not within 1% of the values in step 62 then
recheck transformer connections as per the wiring diagram. Repeat the steps above
when PCS100 AVC-40 is re-powered.
1.10 External Transformer Thermal Test (Optional)
This test is not required for normal commissioning. This is a special test which permits a full current thermal test
for the transformer. It should only be performed if there is special requirement to check the transformer and in
consultation with the factory. Standard units are type tested and do not require this test. It requires an external
bypass circuit.
No
Description
67.
Ensure bypass switch S1, S2, S3 are closed, and the load isolator switch is open or the
load turned off.
68.
Ensure the load is turned off. Power up the PCS100 AVC-40 if not already powered up.
Log in on the GDM using the Tech Access password.
69.
Set 21 Test Mode to OUTWAVEPLL.
Voltage until the load current on the GDM status screen equals approximately 95%. At
this time full rated load current will be flowing through the short circuit on the supply
side of the Injection Transformer created by switches S1, S2 and S3 as shown in Figure
0-1. Allow temperatures to stabilise (will take several hours) and check the
transformer, switch, and cable connection temperatures are not excessive.
70.
At the end of this test stop the PCS100 AVC-40. Set 21 Test Mode to NONE and 22
Test Voltage to 0V.
