System technical characteristics
| 1.Using the latest research and development of testing technology, to detect the high accuracy of fault. 2.Overhead distribution lines using the method of zero sequence current, five times harmonic method, etc. Greatly improve the single-phase grounding fault detection accuracy. 3.Inspection terminal using solar power, long service life. 4.Inspection terminal, center software has two-way communication function, that Can view the latest data on system center any time. 5.Can use the curve display line current change. 6.Can be recorded and indicates the continuous occurrence of failure. 7.The main software direct image display line operation state, straightforward, Using sound alarm after circuit malfunction, and sent SMS to related management personnel mobile phone in time. 8.The SMS to mobile phone only show the information of a test in front of the terminal, avoid all terminal transmitting before point of failure interest rates, that cause mobile phone received dozens of text messages, not easy to identify the specific point of failure. 9.Use of the existing GSM/GPRS wireless network, widely used, all the transmission lines, distribution lines, low-voltage line of one electric power company just need one monitoring center. 10.Master station software is powerful functions, have a lot of management functions, and can upgrade continuously according to user requirements. 11. Close communication with wireless communications. |
Product main function
1.Online monitoring of the short circuit fault and earth fault, over-current, off line, theft case, load current, lack of phase, line charged off power, sending and instructions, distribution transform monitoring, user boundary fault terminal, acquisition real-time data of circuits, and so on. 2.Monitoring line load current, and display the current level on mobile phone APP, Email, save the data on the web cloud, change curve on the system center. 3.Can be used as power supply circuit maintenance intelligent inspection system, monitoring maintenance personnel whether to inspection the power line on time. 4.The hardware and software with functions of bidirectional transmission, that Can view the latest data on mobile phone APP and computer terminals. 5.Monitoring the power line other parameters, according to customer's requirements. 6.Remote sensing (remote sensing information), remote measurement, acquisition and transfer operation parameters, Including all kinds of electric parameters (on line current, frequency, etc ) and load current, etc. 7.Remote communication (remote communication information), remote signal, When the fault occurs, collect and transmit the current status information back to system center for confirmation State. |
