In one embodiment, the cloud platform built into the analyzer may include: the high-voltage branch system and the special transformer line loss analysis and ultra-capacity monitoring system have the advantages that the first page of the platform is the entrance of system products, and the system products are mutually independent. Clicking each system icon to enter each system product; for example, the special transformer line loss analysis and ultra-capacity monitoring system and the high-voltage branch system are respectively different customized product pages. Clicking on the "data analysis" of the left navigation bar of the platform may enter a data analysis page. The data analysis page supports checking of data such as electric energy analysis, line loss rate analysis and current analysis, and supports parameter input. In a non-home mode, the cloud platform can calculate the line loss rate only by manually inputting the parameters of the electric meter. The manual parameter input mode can adopt: clicking the left navigation bar "data analysis"; selecting a task of only binding the high-voltage current acquisition device; click "parameter input"; and completing form filling according to the service. The input of parameters requires that at least 2 groups of complete data are input, so that the data input is supported the next day after the task creation time; the forward active electric quantity and the forward reactive electric quantity are instantaneous values of the meter at the time of 00:00: 00; the voltage value is the average voltage within 24h of a day.

It needs to be noted that the electric energy curve shows the data 7 days before the settlement deadline, and the meter reader task supports 5-dimensional query of 1 hour, 4 hours, one day, three days and seven days. The high-voltage current collection device only supports the inquiry of 3 dimensions of one day, three days and seven days, and the electric energy analysis graph can show the high-voltage actual measurement electric quantity and the meter active electric quantity.

When a loss rate curve in data is checked, values including transformer no-load and load loss are included in the loss rate and loss amount of the transformer; the loss rate and loss amount of the transformer are not contained, and the loss rate and loss amount of the transformer are values of no-load loss and load loss of the transformer. During current analysis, data of tasks which are in operation and finished can be checked, the tasks which are created and neutralized do not support data checking, and actually measured A, B, C three-phase current and meter A, B, C three-phase current can be displayed in the current analysis.

Alarm inquiry can be carried out in the platform, and the inquiry of alarm details according to the occurrence time, tasks and alarm categories is supported. Categories of alarms may include: the number of lost collectors: the judgment basis is that the number of the messages is not increased for 20 minutes continuously, and the messages are reported for 3 times at most every hour; number of reader loss: the judgment basis is that the number of the messages is not increased for 20 minutes continuously, and the messages are reported for 3 times at most every hour; the high-voltage tong head is under-voltage to alarm: the judgment mode is that the voltage of the high-voltage clamp head is lower than 3v, and the high-voltage clamp head reports 3 times at most every hour; and (3) alarming the abnormal current of the high-voltage tong head: the judgment method is that the instantaneous current of the high-voltage tong head is less than 0A in 5 minutes, and the instantaneous current is reported for 3 times at most every hour; line loss rate early warning: the judgment mode is that the line loss rate of the transformer exceeds the interval of plus or minus 30 percent, and the reporting is carried out for 3 times at most every day.

The platform may also support report applications, report abandonment, and report review and export. The report details can be directly checked conveniently, and the report contents can comprise monitoring data and trends, analysis results and expert suggestions. In order to facilitate the inquiry of a user or the inquiry and the watching of a manager, the report can be exported and printed as a paper document for observation and analysis. The report that is no longer used can be deleted to save storage space.

The platform can also comprise options such as a user center, my equipment and the like which are convenient for a user to manage information, for example, the total number of equipment, the number of used equipment, the number of idle equipment, the number of offline equipment and the number of scrapped equipment can be displayed in my equipment; and support querying devices by device number, device type, and occupancy status. The announcement information in the platform can be displayed on a home page interface in a carousel mode, so that a manager can know the information conveniently.

The platform also comprises an alarm bell mark, when alarm information exists, a red point prompt is arranged on an alarm bell icon, and an alarm information list can be seen by turning on the alarm bell; clicking a red button, wherein all marks are read, all alarm information in the list is read, and the list is emptied into 0 new alarm information; clicking a single piece of alarm information, directly opening the alarm details, jumping to an alarm query page, and marking the alarm details as a read state; and clicking a button for checking all alarm information, and directly jumping to an alarm inquiry page to display all alarm information. The user can conveniently check and manage the alarm information.

When the special variable line loss system in the platform cannot inquire the statistical data of the electric quantity and the line loss rate, the following problems may occur: (1) the device time is not consistent with the server time. For example: recovering the equipment time to default time which is far earlier than the current server time after the disconnection, wherein the equipment time has no statistical data of the current time; (2) no meter parameters were entered. The tasks established by the single high-voltage current acquisition device are counted after meter parameters are manually input; (3) the operating mode selection is wrong. The meter reader selects a terminal mode, and the high-voltage current acquisition device selects a non-terminal mode. If the meter reading device selects the non-terminal mode, the metering and meter reading functions are closed, and the platform does not carry out data statistics. (4) The binding clip is unbound or not activated. The high-voltage tong head data can be normally received only after the tong head is started. The platform user can perform troubleshooting on the problems so as to successfully inquire the statistical data of the electric quantity and the line loss rate in the platform.

When the line loss rate of the special transformer system is calculated incorrectly or is abnormal statistically in the platform, the method can be conveniently checked from the following steps: (1) whether a binding clip link mode is consistent with field configuration or not when a task is established; the high-voltage binding clip link mode refers to whether the high-voltage binding clip data are uploaded to an indoor reader or a non-indoor reader, and the link mode must be correctly selected according to practical application, because the data analysis interface display in the two modes is different (the mode of the non-indoor reader has manual input parameter items), and the data statistical mode is different. (2) Checking whether the working mode and the wiring mode are set correctly; (3) checking whether the PT and CT transformation ratio setting is correct; (4) checking whether the configuration of the binding clip is correct or not, and ensuring that 3 binding clips upload data normally; (5) checking whether configuration parameters of primary voltage, the type of the transformer and the capacity are correct or not; (6) checking whether the manually input parameter data is correct (only non-home readers have input parameter items); (7) checking whether the equipment or the tong head is broken to cause excessive packet loss, so that the statistics is inaccurate; (8) check to see if the device time is abnormal (e.g., power down restore default time 2020-4-709: 00); (9) checking whether the current data of the binding clip is abnormal or not, and uploading invalid data all the time when the binding clip is abnormal, so that the statistics is inaccurate; whether the data uploaded by the tong head is abnormal can be determined by checking the alarm of 'high-voltage current abnormity'.
