The importance of electrostatic measurement for studying static electricity and preventing electrostatic hazards
In order to grasp the law of electrostatic charging, to understand the situation of static electricity in the production process, to identify the danger of static electricity in the production process, and to verify the effectiveness of electrostatic safety measures, it is necessary to measure static electricity.
Electrostatic measurement is very important for studying static electricity and preventing electrostatic hazards. In order to grasp the law of electrostatic charging, to understand the situation of static electricity in the production process, to identify the danger of static electricity in the production process, and to verify the effectiveness of electrostatic safety measures, it is necessary to measure static electricity. Although some static parameters seem to be arbitrarily calculated, due to the complexity of the actual conditions, it is often difficult to obtain satisfactory results by calculation alone, but must rely on measurement. In addition to directly considering the safety issues in production, it is necessary to measure the parameters of static electricity. In the research work on static electricity and the production process using static electricity, it is also necessary to measure the parameters of static electricity.
Electrostatic measurement mainly includes two aspects, namely the measurement of electrostatic parameters and the measurement of electrical parameters of materials or objects. The electrostatic parameters include electrostatic voltage, electric field strength, charge amount, weak current, spark discharge energy, electrostatic discharge current waveform, electrostatic discharge radiation electromagnetic field, and the like, indicating parameters of charging characteristics. The electrical properties of the material or object include characteristics such as resistance or resistivity, dielectric constant, and capacitance. In many cases, process parameters and environmental conditions such as flow rate or operating speed, pressure, mixture concentration, temperature, humidity, etc., need to be measured for safety purposes.
Different measurement methods should be used depending on the degree of danger at the site. In places where the risk is high, it is necessary to issue a dangerous signal in advance or need to be automatically controlled, or to monitor the static change for a long time, the static measuring instrument of the EST102 vibration type should be used, and the fixed monitoring method should be adopted. In places where the risk is small and the process is stable, the EST101 electrostatic voltmeter type can be used for periodic measurement according to the situation. In addition, the necessary static measurements should be made in the process of changing the process or other conditions that require the identification of static hazards.
