∆ Exercise caution regarding open phases
∆ Check for faulty wiring connections
∆ Stay clear of coaxial cable target conductors
Non-contact phase detectors are the
SAFEST way to detect phase sequence
especially in high voltage environments
where work safety is of utmost concern.
When using a
non-contact
phase detector:
When an electrical conductor is open-phase,
capacitive coupling with the adjacent conductor
(hot wire) induces a voltage in the open-phase
conductor. Under these conditions, the phase
detector will react to the induced voltage and
determine that the wire is hot, regardless of
its open-phase status. Apart from open-phase
issues, faulty wiring connections may cause
two of the three phases other than the N wire
to have the same phase. In instances such as
this where there is a special wiring problem,
the phase detector will be
unable to correctly
coaxial cables
metallic
shielding interrupts the closed circuit
special
circumstances demand attention
Non-metallic contact phase detectors are
designed to give top priority to the safety
of technicians involved in electrical work
an d wi r ing che ck s. W i t h in high vol t age
environments such as power utilities, the
advantages of this type of phase detector
are
indispensable because it brings about
maximum protection for the field technician,
protecting them from unnecessary danger
and contributing to effi cient productivity and
enhanced safety at the workplace.
