Zy-a038 Three-phase handheld electrical inspection instrument (Grade 0.5)

An overview,

The two-way station branch identification instrument produced by our company is a high-precision testing instrument that integrates the functions of station user identification, line branch identification, electrical independence testing between stations, basic electrical parameters testing, voltage and current harmonic content measurement and so on. The instrument adopts the current industry advanced technology and special zero frequency carrier pulse current emission and detection technology, can effectively guarantee the measuring radius is enough to cover all kinds of power supply area users accurate identification of the distance, there is no more than one variable short of high-pressure situations crosstalk, power carrier transmission distance close, affected by the load is large, a total of cable interference, etc.; The recognition success rate can reach 100 percent.
