[0002] Electrical inspection is generally an inspection of electrical fire safety. Electrical fire safety inspection is based on modern physical phenomena such as thermal radiation, acoustic emission, electromagnetic emission, etc. during the operation of electrical facilities. It uses internationally advanced high-tech instruments and equipment, combined with traditional inspection methods to conduct comprehensive quantitative monitoring of electrical facilities.
