[Case Study] When the overseas compressor operates, a leakage current alarm is triggered.

I want you to clarify the cause of the alarm sounding! Here is an introduction to noise countermeasure examples!

Since it has already been confirmed by the customer that there are no abnormalities in the equipment's insulation, we considered another possibility. Generally, high-frequency noise is generated from the compressor. Typically, some noise reduction product is installed on the compressor to prevent the high-frequency noise generated from affecting surrounding equipment. Under normal circumstances, that noise reduction product should be able to sufficiently prevent the outflow of high-frequency noise. However, when several adverse conditions overlap, that noise reduction product can sometimes become a cause of high-frequency noise dispersion. Upon confirming with the customer, it was noted that a noise reduction product is also installed on the equipment's compressor, so we focused our investigation on the surrounding area. *For more details, please refer to the PDF document or feel free to contact us.*
