Base station cluster: Base station cluster is composed of multiple base stations. This system design can be compatible with 255 base stations. The base station adopts all-cast aluminum shell, waterproof design, and is installed at the secondary output end of 10kV transformer. Its built-in GPS module,4G module and 315MHz/433MHz wireless communication module serve as reference standard source. The base station transmits the collected phase, frequency and other signals to the server through the Internet. The data detected by the base station serves as the comparison standard source, and the data detected by the collector is compared with the source data of the base station
Server farm: Multiple servers form a server farm. The server can receive data from the base station, handheld receiver, and collector respectively. The server first analyzes and compares the data of the collector with the data of the base station, obtains the phase difference and other parameters, and then sends the analysis results to each hand-held receiver. The hand-held receiver users can receive the phase information detected by any collector in real time, and can accurately identify the standard A phase,B phase,C phase, including the ce without any communication signal in the basement phase core phase, and unify Color code work.
Detector: Detectors with different functions including nuclear phase and current, all of which have built-in GPS module,4G module and 315MHz/433MHz wireless communication module, among which the current detector is integrated hook design and built-in multi-layer flexible coil. The 315MHz/433MHz wireless communication module is convenient for handheld receiver to use in short distance meter reading. GPS module and 4G module communicate with the server and transmit data; Multilayer flexible coil is used to collect current and current waveform, frequency, phase and other signals
Flexible Coil: The Rogowski Coil, using multi-layer coil technology, is a coil in non
ferromagnetism

Hysteresis effect
The phase error is almost zero. The lower the phase error is, the more accurate the high-voltage nuclear phase is. Flexible coil None
Magnetic saturation
Phenomenon, linearity is very high, can meet the test of large current. The output signal is the differential of the current with respect to time. By integrating the output voltage signal, the input current can be truly restored. The measured current range can be from milliamps to tens of thousands of amps. The purpose of using multi-layer flexible coil is to improve the resolution of leakage current detection, can reach 10mA, and solve the test of large current, high harmonic current (up to 400 times), complex waveform current, transient impulse current and restore its waveform
Handheld receiver: 3.5 "true color LCD screen design, built-in GPS module,4G module,315MHz/433MHz wireless communication module, to receive the data sent by the server, but also to the collector, the base station meter reading. The receiver disys real-time phase, frequency, current and other information on the same screen, with "X signal is normal,Y signal is normal,Z signal is normal,A phase,B phase,C phase, same phase, different phase" and other voice prompts, clear and intuitive, different functions of the receiver disy content is different
Insulation rod: telescopic insulation rod, stretching length about 5 meters, about 1 meters after contraction, light, with moisture-proof, high temperature resistance, impact resistance, high insulation, telescopic and other characteristics, connected to the collector, can be hung in the line test, can also be lengthening or reducing the length of the insulation rod according to the actual needs
