[Case Study] An alarm for leakage current is triggered when the overseas compressor operates.

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

Since you have already confirmed that there are no abnormalities in the insulation of the equipment, 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. In principle, 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 dispersing high-frequency noise. Upon checking with the customer, it was confirmed that a noise reduction product is also installed on the compressor of the equipment, so we focused our investigation on the surrounding area. *For more details, please refer to the PDF document or feel free to contact us.*
