GPS Wireless High Voltage Phase Detector

GPS Wireless High Voltage Phase Detector

The MOEORW-WTA65 wireless high voltage phase detector is a multi-functional testing device integrating close-range phase detection, three-phase sequence measurement and GPS remote phase detection. It is used to measure phase difference between two or three high-voltage lines, judge in-phase status for grid connection, and identify three-phase sequence. The equipment also realizes remote phase alignment and phase color marking calibration via GPS timing technology, and retains high-voltage live line detection function.The device is divided into close-range testing system and remote testing system. The close-range part uses X, Y, Z transmitters to collect line phase data and transmit to the main unit. The remote testing adopts dual main units with GPS timing to synchronize measurement time, so as to complete long-distance phase detection between different locations.

1. Close-range Two-line Phase Detection: X and Y transmitters collect frequency and phase signals of two lines and transmit wirelessly. The main receiver calculates phase difference to distinguish in-phase (＜30°) and out-of-phase (≥30°).

2. Three-phase Sequence Measurement: X, Y, Z transmitters sample three-phase signals simultaneously. The main unit judges forward sequence (each phase difference 120°) or reverse sequence (each phase difference 240°) based on pairwise phase differences.

3. Remote Phase Detection: Two GPS-enabled main units obtain unified clock via satellite timing. The phase values collected by respective Y transmitters are compared to judge long-distance phase relationship.

Hardware & Structural Design Configured with multiple transmitters to support two-line phase detection and three-phase sequence testing. Equipped with GPS module, which automatically switches between GPS timing mode and internal clock mode according to satellite signal strength. All batteries are detachable for easy replacement and field maintenance.

Performance Advantages High-definition color screen displays phase difference, frequency, vector diagram, battery level, GPS information, longitude and latitude synchronously. Real human voice reports test results. The equipment adapts to complex field environments and ensures stable measurement accuracy for both short and long distance tests.

Application Value One device meets multiple testing requirements including close-range phase matching, three-phase sequence inspection and long-distance remote phase calibration. Remote phase detection unifies phase color marking of the whole power grid, reducing power outage and construction time for grid transformation.
