Workers (operators) wearing synthetic clothing and moving around easily generate static discharge. Additionally, friction, stirring, and movement of packaging products or周转 equipment in high-temperature rooms also produce static electricity. The static electricity can easily cause electronic components to break down and burn, affecting the accuracy of detection equipment and instruments and causing computer systems to malfunction. The sparks from static electricity are also sufficient to ignite and explode flammable and explosive gases such as natural gas, oil, and alcohol. Therefore, proper grounding is required for equipment, containers, and pipelines that are prone to static electricity generation, as well as for production processes that are prone to static electricity. Grounding refers to the electrical connection between a specific point in a system, device, or equipment and the local ground (earth). Thus, the lower the resistance, the faster the current flows, and the higher (or safer) the level of equipment (or grade) that can be protected. Moreover, good grounding can effectively reduce static noise in computer systems caused by potential changes.

Types of Grounding: Work Grounding, Protective Grounding, Static Dissipation Grounding, Lightning Protection Grounding, Repeated Grounding, Isolation Grounding, Shielding Grounding, Signal Grounding for Electronic Equipment, Power Grounding for Electronic Equipment, etc.

Based on international and domestic standards: The static grounding resistance values (ground resistance values) are divided into three grades:

        ①.≤1Ω; ②.≤4Ω; ③.≤10Ω; 

General Requirements:

Communication Working Site: ≤4Ω

Safety Protection Resistance: ≤4Ω

Anti-static grounding: ≤4Ω

Surge Protection and Grounding: ≤10Ω

Manufacturers or laboratories can select the appropriate ground resistance value based on their specific environmental requirements.

Recommendation: The ground resistance value for general factories can be required to be ≤10Ω (but it should be ≤4Ω if all equipment needs to be connected); for example, in chemical factories (manufacturing hazardous chemicals) and factories producing and processing flammable and explosive gases, the ground resistance value should be required to be ≤4Ω or higher. For electronic factories, semiconductor factories, inspection laboratories, and computer systems (cleanrooms of 100 grade or above, electronic components with withstand voltage not exceeding 100V), the ground resistance value should be required to be ≤4Ω or higher.
