Test operation steps of insulation oil dielectric strength tester

The dielectric strength test of insulating oil is a test method used to measure the dielectric strength of insulating oil, which can evaluate the insulation performance of insulating oil in electrical equipment. The dielectric strength tester for insulating oil is a specialized device that generates breakdown phenomenon in insulating oil by applying high voltage, thereby obtaining the dielectric strength value of insulating oil. The following are the test operation steps for the dielectric strength tester of insulating oil:

Step 1: Equipment preparation

① Ensure the working status of the testing instrument is normal, check the power supply, and confirm that the equipment is in a usable state.

② Clean the testing instruments and electrodes to ensure that their surfaces are clean and free from oil or impurities.

③ Prepare insulation oil samples to ensure their accuracy and representativeness.

Step 2: Set experimental parameters

① Turn on the power switch of the insulation oil dielectric strength tester and start the equipment.

② According to the test requirements and standards, set the parameters of the testing instrument, including voltage, test time, etc. Set appropriate parameters as needed.

Step 3: Electrode installation

① Connect the two electrodes to the testing instrument, ensuring that the electrode plug is securely connected to the slot.

② Gently insert the electrode into the insulating oil sample, ensuring that the end of the electrode is in full contact with the sample.

Step 4: Conduct the experiment

① Press the start button or corresponding test button on the device, and the testing instrument will apply a certain voltage to the insulation oil sample.

② Start the timer and maintain a certain test time. Generally, the test time is 1 minute.

③ During the experiment, observe the changes in instrument data to ensure the accuracy and reliability of the experiment.

Step 5: Record the results

① After the test is completed, carefully record the test results, including the test date, identification of the insulation oil sample, applied voltage value, and test time.

② Turn off the testing instrument and pay attention to safe operation.

Step 6: Data processing and analysis

① Organize and archive the experimental results for subsequent data analysis and comparison.

② Based on the test results, evaluate the dielectric strength of insulating oil and determine its insulation performance and reliability in electrical equipment.

It should be noted that the above steps are only general operating procedures, and actual operations may vary depending on the equipment model and manufacturer’s requirements.
