    Product description

    GDHX-9000 is used for phase detection of power supply on both sides of closed-loop point circuit breaker, in order to avoid short-circuit in power system. It is composed of three parts, a transmitter, a receiver and an adjustable insulated rod. The receiver will indicate test result of in-phase or out of phase. It allows two engineers to proceed the test.


    Features

    • Power supply: Maintenance-free battery with large capacity and very low consumption (Lasting for one year after a single charge). Suitable for field work.
    • Safe design, in accordance with safety standards for mining equipment.
    • Far measuring distance,up to 200M. Signals can be received through the wall.
    • LCD show data such as phase position, waveform, and frequency synchronously, which guarantees an overall and safe test.
    • Extended insulation rod, portable receiver.
    • Small size and light weight.


    Specifications

    • Detectable voltage range: 0.4-500kV(standard is 6-110kV).
    • lWireless transmission distance:  200M of visibility range(customized for more than 300M).
    • Accuracy: 0.1°
    • Definition: phase angle 30°, In-phase; Phase angle 30°, Out of phase.
    • Working frequency: 45-60Hz.
    • Net weight: 5kg.

    Insulation index:

    • High withstand voltage nylon material for 2pcs transmitters.Insulation level is 80kV/cm.
    • Moisture-proof extended insulation rod.The specifications as as below tables.
