Static grounding alarm
Thread Content
After a ship berths at the dock, it is necessary to connect an earth wire. It is desired to have audible and visual alarms in case there is no reliable connection. How can this be achieved? What is the principle behind it? Thank you
The specific principle isn’t clear, but I know such a device exists; you can look it up on Baidu. It’s likely that the high resistance is what triggers the alarm
As a supplementary note, searching for \"static electricity alarm\" on Baidu will reveal the manufacturers
Okay, thank you. But I also searched on Baidu, and there are only sites that sell the products, with no explanations of how they work. Hehe
If the phone number can be found online, you can ask about it; this way you can also get the information you need.
Static grounding protection is used in train or vehicle loading systems, especially in those for loading flammable and explosive materials. I wonder if it is the same as that used on ships.
Replying to the person above: It’s the same here. Our company has installed static grounding systems both at the loading platforms and at the docks. To ensure reliable grounding, the system comes equipped with audio and visual alarm functions
