Safety First: Live-line testing must strictly adhere to operating procedures to avoid electric shock or short circuits.
Environmental Interference: Keep testing away from strong electromagnetic fields (such as frequency converters and large motors) to prevent data distortion.
Regular Inspection: It is recommended that low-voltage cables be inspected every six months, high-voltage cables every quarter, and critical lines be inspected monthly.
Professional Training: Testing personnel must undergo professional training and be familiar with equipment operation and leakage current assessment standards.
