Omicron CPC 100 User Manual

CPC 100 V 3.20
Transformer - 5
Use the RWinding test card to measure the resistance of a power transformer’s winding as
described on page Current Transformer-4. Alternatively, inject the current directly from the
400A DC output as shown below.
The Tap Changer Cleaner Sequence is used to sweep all taps before performing a Winding
Resistance measurement to ensure that the taps are clean.
Note: The Tap Changer Cleaner Sequence can only be activated if the CP SB1 transformer
switch box is connected and Auto-tap is selected.
The currently sweeped tap and the remaining time are displayed during the sequence.
Note: You can only interrupt the Tap Changer Cleaner Sequence by pressing the Emergency
Stop button.
