MEWOI2500 Wireless High Voltage Phase Detector
INSTRUCTION
MEWOI2500 Wireless High Voltage Phase Detector is specially designed and manufactured for high voltage line and high voltage switchgear (middle cabinet, ring network cabinet, etc.) nuclear phase, the instrument breaks through the traditional nuclear phase device voltage grade limit problem, can be in the very low voltage line nuclear phase, completely realize from 10V to 500kV voltage automatic nuclear phase. Adopt wireless transmission technology, phase detecting distance 200m, phase detecting accurately, operation convenient. Adopt 3.5inch LCD color screen can display the phase, frequency, phase sequence, and phase detecting results on the same screen. The dynamic vector diagram indication, clear and obvious.Adopt 3.5inch LCD color screen can display the phase, frequency, phase sequence, and phase detecting results on the same screen. The dynamic vector diagram indication, clear and obvious. MEWOI2500 Wireless High Voltage Phase Detector is composed of host, detector, telescopic insulating rod, monitoring software, USB communication line and so on. The host adopts 3.5-inch LCD color screen, which can display phase, frequency, phase sequence and nuclear phase result on the same screen. With Voice prompt: "X signal is normal, Y signal is normal, same phase, out phase"Monitoring software has the functions of online real-time monitoring, historical data query, vector graph indication, and phase indication; it has functions such as historical data reading, viewing, saving, and printing. |
