Pressing the TEST button again will start a new Continuity test
(assuming the user fixed the connection problem) again. If it passes the
Continuity test, Ratio test will be executed
Transformers with winding arrangement multiple, parallel paths (e.g.,
Delta type) may read CONT even if one or more windings may be
OPEN
4.2.5. CT test
In this section, an example of running a test using the following
configuration (see § 4.3 for how to configure the instrument) is shown:
Set Date/Time: July 4, 2010. 6:00 PM
Set values in Nameplate:
Primary Current: 19920; Secondary Current: 7200
Select Type: CT
Select Test Mode: Ratio
Storage Mode: Manual
Set Filter: Normal
Set Language: English
Note: CT test does not allow a CONT/Ratio option. It only runs a Ratio test .
WARNING: The TR8703 is designed for use on de-energized
("dead") transformers only. Make sure the test sample is
completely disconnected from AC power and is fully discharged.
1. Connect the Primary (H) cable to the appropriate connectors on the
TR8703 and the transformer under test. Connect the Secondary (X)
cable as a loop through the current transformer hole as shown in the
figure below.
