Usage of Wireless Zinc Oxide Arrester Tester:
Turn on the power switch, and after a few seconds of the startup screen, the main menu as shown below will appear (Figure 6).
Figure 6
The specific operation instructions for the main menu of the wireless zinc oxide arrester tester are as follows:
1. Line Number: Press the "Function" key to move the cursor to "Line Number", then press "OK" to enter; press the "Function" key to select the position to adjust, and a small cursor will appear under this position; press the "Increase" and "Decrease" keys to select. After all positions are adjusted, 2. PT Ratio: Press the "Function" key to move the cursor to "PT Ratio", then press "OK" to enter; press the "Function" key to select the position to adjust, and a small cursor will appear under this position; press the "Increase" and "Decrease" keys to select. After all positions are adjusted, press the "OK" key.
3. Test Phase Sequence: Press the "Function" key to move the cursor to "Test Phase Sequence", then press "OK" to enter; press the "Function" key to select the position to adjust, and a small cursor will appear under this position; press the "Increase" and "Decrease" keys to select. After all positions are adjusted, press the "OK" key. Among them, A, B, C represent single-phase measurement, and X represents three-phase simultaneous measurement.
4. Compensation Angle: The adjustment method is the same as above. Generally, the influence of interphase interference is about 2°- 5°. Since it is difficult to accurately calculate the interference amount, hard compensation is generally not recommended, but it is set to 0.0°. You can compare the data change trend over a period of time according to the regulations. If you need to adjust the side phase correction angle, refer to the relevant chapters in "Measurement Principle" later. If three-phase simultaneous measurement is selected, the angle is automatically compensated.
5. Date: The adjustment method is the same as above. Use the "Function" key to select the item to adjust: year, month, day, hour, minute, second, and use the "Increase" and "Decrease" keys to adjust. After all adjustments are completed, press the "OK" key.
6. Mode Selection: Press "OK" to switch between four modes: (PT Secondary), (Induction Plate), (Wireless Transmission), and (Synchronous Display).
7. View: Press the "Function" key to move the cursor to "View", then press "OK" to enter (as shown in Figure 7); press the "Increase", "Decrease", and "Function" keys to select the data to view, and press "OK" to display that set of data;
8. Measurement: Press the "Function" key to move the cursor to "Test", then press "OK" to enter measurement, and the measurement screen as shown in Figure 8 will appear.

After the wireless zinc oxide arrester tester completes the test, the test results will appear, as shown in Figure 9.
Figure 10 Figure 9
Display: Switch the display screen to show all test information or a brief display. If it is three-phase simultaneous measurement, press "Increase" and "Decrease" to cyclically display the information of the three phases.
Print: Can print the measured data, but not store it.
Store: Store the current data. Select the storage location for the data and press "OK" to save.
Exit: Exit the measurement and return to the system main menu.
