1. When unpacking, the test personnel should check the equipment against the packing list. If any discrepancy is found, please contact our company immediately.
2. This test equipment should be used by professional high-voltage test personnel. Before use, read the instruction manual carefully and undergo repeated operation training.
3. At least two test personnel are required. During use, strictly comply with your unit's safety operation regulations for high-voltage tests.
4. To ensure the safety and correctness of the test, besides being familiar with this product manual, strictly follow national standards and procedures for test operations.
5. All connecting wires must not be connected incorrectly. Wiring must follow the circuit diagram in the "Precautions" section; otherwise, the test device may be damaged.
6. When this device is in use, it outputs high or ultra-high voltage. It must be reliably grounded, and attention should be paid to operational safety.
7. Before testing the test object, perform a no-load test on the equipment with a test voltage of 80% of the rated voltage.
8. Whether testing the test object or performing a no-load test, the lower section of the reactor must be isolated from the ground using an insulating support.
9. During the test, keep as much distance as possible between the variable frequency power supply and the reactor (to avoid safety accidents).
10. The variable frequency power supply part of this device is touch screen. When operating, press lightly and slowly (with a 0.5-second interval between entering the next menu). If pressed too hard or too fast, it may fail to enter the next menu or the machine may not start. Press the reset button, return to the main menu, wait 5 seconds before restarting, or directly turn off the power and restart.
11. When setting parameters on the device, the "Device Voltage" field must not be changed. "Device Voltage" is set in conjunction with the voltage divider during factory testing. If "Device Voltage" is changed, the voltage divider sampling signal will change, and the measured voltage will not be the true test voltage; it may be higher or lower. This can affect the withstand voltage test of the test object. Therefore, test personnel should record the "Device Voltage" at startup so that it can be referenced if accidentally changed.
12. When testing objects with relatively large capacitance or high losses, such as "generators, large-capacity motors, cables longer than 1.5km", the system Q value is low. Set the "Output Voltage" between 30V and 50V. Under normal circumstances, set the "Output Voltage" between 10V and 20V. When testing cables below 10kV and within 500m in length, choose a lower excitation voltage and set the "Output Voltage" to 10V. Otherwise, when searching for the resonance point, the test voltage may exceed the rated withstand voltage of the test object, and the system Q value is high, which can easily cause breakdown of the test object.
