Questions about static electricity
Thread Content
When entering the production area, it is well known that fire and static electricity prevention are necessary; generally, static electricity elimination facilities are installed outside. Here comes the question: over time, how can we determine whether it still remains effective in providing fire-resistant static control? What if it can no longer fulfill this function? How do you all handle such situations? ? ?
MI writing preventive maintenance: Ground resistance value to be checked annually
Was it you who conducted the testing? What kind of instrument is used? Could you recommend one?
Every year, testing is carried out by qualified external agencies; in addition, regular internal testing is conducted, and it can also be done by dedicated electricians.
For static grounding, the resistance value can be determined by us ourselves; it’s very simple. We can handle remote monitoring as well. For lightning protection grounding, a qualified entity is required, such as the Lightning Protection Testing Center in XXX City
Two annual inspections are carried out each year, and the only testing facility at present is the Lightning Protection Center of the Meteorological Bureau. The others can only be used for internal reference. Daily checks can be carried out by electricians; there are now meters that are easy to use, much more convenient than the oscillating meters used in the past. It is recommended to use it.
The static electricity bonding is good, and the equipment is properly grounded. Using grounding as the reference point, the resistance of each point to ground was measured, and it met the requirements.
If static electricity is a real concern, then one can purchase electrostatic discharge devices with electronic displays; such devices can perform self-checks and indicate when the static electricity has been removed
This can be entrusted to electrical technicians for inspection, and anti-static equipment should also be included in the routine inspection schedule to be checked from time to time. At the same time, strict requirements must be imposed on the clothing worn by workers.
For the static ground resistance value, we can measure it ourselves; it’s very simple. We’ll do the measurement remotely
