The visible corona and radio interference test of the suspension clamp are important indicators for evaluating its electrical performance. The following are the detection methods for these two tests:

1. Visible corona test
Test preparation:
Ensure that the test environment meets the requirements. It is usually necessary to conduct it in a dark room or at night to observe the corona phenomenon.
Prepare necessary test equipment, such as booster, night vision device, etc.
Test steps:
Install the suspension clamp on the test device and connect the booster.
Slowly increase the voltage until the visible corona on the suspension clamp or nearby area can be observed using the night vision device.
Continuously observe and record the corona phenomenon, usually for about 5 minutes.
Slowly reduce the voltage until the corona disappears, and record the voltage value at this time.
Repeat the above process several times (such as five times) to obtain a stable average value.
Test result evaluation:
Based on the recorded voltage value and the observed corona phenomenon, evaluate whether the visible corona performance of the suspension clamp meets the relevant standards or requirements.
2. Radio interference test
Test preparation:
Prepare necessary test equipment, such as booster, radio interference tester, etc.
Ensure that there are no other radio interference sources in the test environment to avoid affecting the test results.
Test steps:
Install the suspension clamp on the test device and connect the booster.
Raise the voltage to the specified value to ensure that sufficient radio interference signals are generated.
Use the radio interference tester to test the radio interference voltage generated by the suspension clamp and record the test results.
Test result evaluation:
According to the recorded radio interference voltage value, evaluate whether the radio interference performance of the suspension clamp meets the relevant standards or requirements.
Precautions
During the test, the relevant safety regulations and operating procedures should be strictly followed to ensure the safety of personnel and equipment.
The test equipment should be calibrated and verified to ensure the accuracy and reliability of the test results.
The test data and observations should be recorded in detail during the test for subsequent analysis and evaluation.
In summary, the visible corona and radio interference tests of the suspension clamp are important means to evaluate its electrical performance. Through strict test methods and evaluation standards, it can be ensured that the electrical performance of the suspension clamp in actual application meets the relevant requirements.
