The Phase Sequence Tester
is an invaluable device that enables the
testing of 400 Hz generating systems for
proper wire connections after repairs,
modifications, installations or cable
replacements.
When generators are overhauled and circuit
breaker panels are worked on, there is always
the risk of misconnection, resulting in reverse
phase rotation.
The Phase Sequence Tester can detect improper
connections before full power is applied, thus
avoiding costly aircraft delays.
