Wuhan Huayi Electric Power Technology developed the three-phase secondary injection tester. It meets all the requirements of field tests. This tester with standard 4-phase voltage, 3-phase current output, voltage 125V/phase, current 40A/phase, 3 phases in parallel can up to 120A. Digital Signal Processor Microcomputer.
There are some general rules which should be noticed when testing.
1. This tester with IPC and Windows operating systems, please do not power on/off frequently.
2. There are USB interfaces on the panel or backboard, that allow hot-swap USB equipment (such as flash disk, etc), but this must be done after the data transmission is completed.
3. In order to avoid operating system corruption caused by the illegal shutdown, deleting, or altering the words of the disk or icon on the desktop, this tester is equipped with a special self-restore CF card. If need store to this tester, please keep it in D drive. When using the USB to copy data, please ensure that the flash disk is clear without viruses; please do not use the flash disk to install other software programs in this system.
4. When connecting the keyboard or mouse, please do not connect the wrong terminal; otherwise, the Windows operating system won't start up normally.
5. Please do not power off directly during outputting conditions so as to avoid the wrong protection action due to the wrong output.
6. Switch input compatible dead contact and electric potential (0～DC250V), when using charged contact, its positive electrode should connect with the COM terminal.
7. During the test make sure that the air slots are not unobstructed, the instrument should be laid upright, or the bracket for slightly tilted.
8. Do not lead external AC/DC power into the voltage and current output sockets of the tester. Or else, the tester will be damaged.
9. If the disturbance is stronger or high safety is required for the field test, before doing the test, please well-ground the power cable (3 cords) or ground hole of the tester.
10. If there were data errors, inability to connect the device, or other problems during use, it can be solved: by exiting back to the main menu and re-run the program, then all the data are restored to default values
