Non-Contact Phase Rotation Indicator,Phase Sequence Indicator
   It is designed for phase-locked loop circuits may be classified in two types. A Type I detector is designed to be driven by analog signals or square-wave digital signals and produces an output pulse at the difference frequency,The Type I detector always produces an output waveform, which must be filtered to control the phase-locked loop voltage-controlled oscillator (VCO). A type II detector is sensitive only to the relative timing of the edges of the input and reference pulses, and produces a constant output proportional to phase difference when both signals are at the same frequency. This output will tend not to produce ripple in the control voltage of the VCO.
Features:
1.Traditional phase sequence measurement methods must poke the three-phase wire terminal, and connect the three bare alligator clips or test pins of phase sequence meters to the three bare firing lines, while PHDE-3001 uses clamp non-contact measurement, without taking off the wire and no need to contact high-voltage bare fire-wire, the test can be made by directly clamping the three-phase insulating sheath by three super-sensitive high-insulated clamps. Conducting measurement on sheathed cable significantly improves the safety of field testing, effectively protect the operator’s personal safety and increase productivity!
2.In addition to phase sequence detection, it also has the functions of live wire examination, simple power detection, fire-wire identification, phase deficiency determination, break location detection, DC line break and line maintenance, equivalent to 3 induction electric pens.
3.LED dynamic display, intuitive and clear
4.It can even sense the AC voltage signal as low as a few Volts, with a wider range of live electricity.
5.In three colors, Red, Yellow and Blue; It is more in line with the distinction of three-phase line, and more scientific and artistic overall appearance.
6.Better power-saving performance with the maximum rated power of 100mVA
