Similar to voltage detectors
,
non-metallic contact phase detectors
like the HIOKI 3129 use voltage clips without exposed metal that employ
the principle of electrostatic induction.
Phase sequence
can be checked by
simply clamping the clip around the
insulation of the conductor being measured. This prevents
t h e dang e r of t h e
te c hnici an com in g
into contact with the
metallic part of either
the phas e de te c tor
or the conductor being
measured.

How does it work?
Non-contact phase detectors offers
safe and correct phase detection based
on the basic understanding that a
closed circuit is formed between the
conductor, detecting device and the
operator with reference to the earth.
