The MEWOI2500C satellite timing remote high-voltage phase detection meter has both ultra-long-distance phase detection and ordinary short-range phase detection functions. The timing accuracy is less than 20nS, and it can receive GNSS signals of six satellite timing systems at the same time, and realize joint timing to ensure accurate phase detection. The normal phase detection distance is 260 meters (in an open space), and the satellite phase detection distance is 500 kilometers. This phase-checking instrument can perform phase-checking not only in high-voltage lines, but also in high-voltage switch cabinets (central cabinets, ring main units, etc.) Automatic phase checking from 10V to 500kV voltage, easy to operate, time-saving and fast. At the same time, it also has the functions of testing phase, frequency, phase sequence, transformer group judgment, etc., as well as power inspection and voltage level display functions. When the line voltage exceeds 110kV, the non-contact phase detection must be used. During the phase detection, the metal probe of the detector is gradually approached to the wire. When the electric field signal is sensed, the phase detection can be completed without direct contact with the high-voltage wire, which is safe and fast. When it is used for the phase-checking of the ring main unit, the detector must use the probe and the test line of the ring main unit.
MEWOI2500 satellite timing remote high-voltage phase detector consists of 2 sets of instruments, each set of instruments includes host, X detector, Y detector, telescopic insulating rod, monitoring software, etc. The host adopts a 3.5-inch true color LCD screen, which can display the phase on the same screen , frequency, phase sequence and phase detection results; vector diagram indication, phase indication, clear and intuitive; with "X signal is normal, Y signal is normal, in-phase, out-of-phase" and other voice prompt functions, making the test easier and easier.
