Principle and characteristics:

DFHX is composed of three parts: launched by the two voltage detection module (including insulating lever), you can determine whether lines are charged, and issued related conductor voltage phase angle signal; the other is receiver modules (display section), sounds, display phase results. Characteristics of the instrument:

1. high reliability: Colonel in the same line before the official nuclear testing phase, reversed phase, guarantees the proper phase in the test method.

2. Security: wireless voice alert, abandoning wired nuclear safety problems.

3. ease of use: instrument does not need more action, operation is simple and convenient.

4. a dual-purpose machine: not only nuclear, but can be used as a voltage high-voltage electroscope, truly a dual-purpose!
