5.14.3 Quick Test Modes
During every test, low voltage (less than 1V) is ap-
plied as a safety and connection test. If no safety or
connection failures are found, the test progress as
per the test mode selection.
Auto test mode uses the results of the safety and
connection test to determine:
1. If the test can be performed in step up mode,
and
2. If a 3Ø test is possible. If a 3Ø test is not possible,
a 1Ø test is executed if no safety or connection
issues are present.
Step up applies voltage to the secondary/tertiary and
induces voltage on the primary.
Step down applies voltage to the primary and induc-
es voltage on the secondary/tertiary.
3Ø applies and measures voltage on all three phases
simultaneously.
1Ø applies and measures all three phases individually.
