1Product introduction

YD Digital wireless nuclei is independently developed and patented products with independent intellectual property, is used to perform many common voltmeters or cable phase of existing functionality.

YD Series main advantages of wireless phase out open circuit point at both ends of the connection leads, instruments using radio signals to communication, the scope can be extended to nearly 20Metres, and can be used through the walls and partitions, than to use a voltmeter or nuclear devices should be simple.

Meanwhile, instrument used analog technology, reducing the weight of the body, improves the comfort of use, can be easily and safely operate one of two instruments.

YD Series of wireless phase are particularly suitable for applications under the specific conditions of use, existing voltage tables are not suitable for use or nuclear situation. In high voltage situations, security and ease of use is the most important factor, HBR Series is the ideal choice for you. Moreover, this device can pass through walls and metal shield to use to solve the problems faced by conventional instruments used.

YD Digital wireless nuclear phase compared to HBR-800More powerful wireless nuclear phase, increasing the phase angle, frequency, waveform display function, the measurement result more intuitive; Equipped with a rechargeable battery, easy to use.

2, structural principle

YD Digital wireless phase consists of three components that are electrically isolated, two transmitter see Figure 1And receiver see Figure 2. Equipped with electrodes on the transmitter can be connected to the conductor to be measured, the electrode shape for a hook in order to hang on to the wire; When two transmitters connected to line the road. These electrodes are used as a transmitting antenna. End of the transmitter should be connected with the insulating lever.

Receivers for handheld devices with a built-in antenna for receiving the transmitter sends digital signals over. Launcher phase signal was received and processed by analysis, the frequency and voltage waveform and phase displays on the LCD.

Transmitter is voltage detector and transmitter combination unit, first determine whether lines are charged and sent signals about the conducting phase. Receiver received transmitter signals, and signals the user when the test conductor to achieve the same.

In use, first for all lines using the HBR-900 transmitter equipment, two lines of contact, they charged were determined by beeping and flashing light. 1 at the open one end of the transmitter, the transmitter in turn 2 on the open point on the other end of the line until you find the transmitter 1 phase conductor circuit. At this time, is displayed on the LCD of the receiving frequency on the two lines, voltage and phase.

HBR-900 as a standard kit with metal packaging for transport and probe for overhead lines.
