Before the electrical system and electrical equipment are put into use, the electrical test is to test the insulation performance, electrical characteristics and mechanical properties of each electrical equipment in the electrical system item by item according to the relevant provisions of standards, procedures and specifications, so as to timely find and eliminate the defects, errors and quality problems of electrical equipment during manufacturing and installation, and ensure that the electrical system and electrical equipment can be put into normal operation.

Electrical test can be divided into delivery test, rc0603jr-07270r handover acceptance test, overhaul test, preventive test, etc. according to different stages of electrical equipment manufacturing, installation, operation and use. According to the different functions and requirements of the test, the test of electrical equipment is divided into insulation test: centralized defect, distributed defect (non-destructive test, destructive test) and characteristic test.

Main items of electrical test

Insulation resistance detection: the insulation resistance measurement of insulator is usually the corresponding resistance when the measurement time is one minute.

Conductive circuit resistance test: the loop resistance value is a parameter indicating whether the connection of the conductive loop is good or not, which is the total resistance of the whole loop.

Grounding continuity test: grounding continuity refers to the electrical connectivity between various electrical equipment that should be grounded in the grounding device, parts of the grounding device and equipment, i.e. DC resistance value. The reliable and effective connection between the grounding conduction of power equipment and the grounding grid is the fundamental guarantee for the safe operation of equipment.

Sulfur hexafluoride gas test: sulfur hexafluoride gas is widely used in electrical equipment insulation, and its insulation performance mainly depends on the water content and gas density of sulfur hexafluoride. If the equipment has leakage point, density change, arc extinguishing and insulation performance decline, and even cause accidents such as insulation equipment damage in serious cases.
