10. Phase detection, phase, frequency, phase sequence test
Danger of electricity! It must be operated by trained
and authorized personnel. The operator must strictly
observe safety regulations; otherwise there is danger
of electric shock, which may cause personal injury or
damage to equipment.
Cannot be used to test more than 220kV voltage line,
otherwise there is an electric shock, causing personal
injury or equipment damage.
The high voltage test must be connected to the
insulating rod and fully stretched with the use of the
insulating rod sheath.
The safety pressure rating of the insulating rod for a
maximum of 220kV, when the voltage exceeds 35kV,
must use the non-contact nuclear phase, non-direct
contact bare wire above 35kV, otherwise there is a risk
of electric shock, resulting in personal injury or
equipment damage.
Connect the insulated pole, turn on the machine, if the host and
detector communicate normally, the corresponding indicator light,
communication is not normal, the indicator light is not bright,

-11-
and the host will voice prompt "X signal normal", "Y signal
normal".
Under phase detection mode, close the X detector to or contact
any phase line, and then close the Y detector to or contact the
other phase lines. High voltage phase detection, without direct
contact with the high-voltage wire, close the hook detector to
the wire gradually, when the electric field is induced the
detector will sound "beep, beep, beep" and the lights flashing,
complete electrical inspection function. Low voltage phase
detection (400V and below), especially for phase detection of
low voltage of distribution box, change metal hook detector into
metal probe.
Non-contact phase detection, If the lines are relatively close to
each other, should test the position of the wire where is far
away from the other wires
Phase detection use X detector as a benchmark, fixed display
A, If the phase difference of the two detector is in the range of
-25°～25°(335°～360 which is-25°～0°), Y detector test
result is A, Qualitatively in-phase; If the phase difference of the
two detector is in the range of 95°～145°or 215°～
265°,Qualitatively Out of phase. At the same time, the host
voice prompts "in-phase" or "out of phase".
When the phase difference is between 95°～145°, the Y
detector result is B phase, that is positive sequence; if the
phase angle difference is between 215°～265°, Y detector
detection result is C phase, that is the inverse phase sequence.
