    Product Introduction
    ETCR1500A Remote Wireless High Voltage Phase Detector, also known as satellite timing high-voltage nuclear phaser, has both ultra-long-distance nuclear phase and ordinary short-range nuclear phase functions. It adopts satellite precision timing technology to achieve long-distance nuclear phase, close-range ordinary nuclear phase, basement nuclear phase, and mine nuclear phase. The timing accuracy is less than 20nS, and the joint timing is achieved to ensure the accuracy of the nuclear phase.Ordinary nuclei are 200m apart (in an open place), and satellite nuclei are 5000m apart.This phase detector can perform phase verification both on high-voltage lines and in high-voltage switchgear (central cabinets, ring network cabinets, etc.), and realize functions such as automatic phase verification, phase testing, frequency testing, phase sequence judgment, power verification, and voltage level display from 10V to 500kV voltage level.When the line voltage exceeds 110kV, a non-contact nuclear phase must be used. During the nuclear phase, the metal probe hook of the detector is gradually approached to the wire. When the electric field signal is sensed, the nuclear phase can be completed without direct contact with the high-voltage wire, which is safe and fast.When used for the nuclear phase of the ring network cabinet, the detector must use a probe and a ring network cabinet test line.
    ETCR1500A Remote Wireless High Voltage Phase Detector consists of 2 mainframes, 2 detectors, telescopic insulating rods, monitoring software, etc. The mainframe adopts a 3.5-inch true-color LCD screen, which can display the phase, frequency, phase sequence and nuclear phase results on the same screen. The vector diagram indication and phase indication are clear and intuitive; it has the “X signal is normal, Y signal is normal, in-phase, out-of-phase” voice prompt function, making the test easier and easier.
    1. Two nuclear phase modes: satellite remote nuclear phase mode and short-range ordinary nuclear phase mode.
    2. Voice broadcast function, voice prompt: “X signal is normal, Y signal is normal, Z signal is normal, positive phase sequence, inverse phase sequence”.
    3. Using a 3.5-inch LCD color screen, the phase, frequency, phase sequence, and nuclear phase results can be displayed on the same screen, and the vector diagram indication and phase indication are clear and intuitive.
    4. The instrument has the functions of power inspection and voltage level display.
    5. Storage function, 200 sets of data storage.
    6. USB communication interface.
    7. Rechargeable lithium battery

    Satellite Searching Indication Dynamically display the “----” symbol when searching for satellites
    Satellite Searching Time The first star search time is about 2 minutes, the second boot after the star search is successful, the star search time is about 15 seconds, and the subsequent hot start is about 1 second.
    No Satellite Continuous Time After the star search is successful, try to continue the nuclear phase until there is no satellite signal, which can last for 1 hour, fully meeting the requirements of the basement nuclear phase and the electric room core.
    Automatically Switch Timing Mode According to the strength of the satellite signal, the satellite receiving nuclear phase and the timing nuclear phase are automatically switched, without the need to choose whether the satellite mode or the timing mode.
