How to test lightning protection grounding in factories
Thread Content
Hello! The factory has its own lightning protection and grounding system, and the regulations state that it should be inspected every six months. Which qualified organizations can be hired for such inspections? Should it be the electrician from this unit who takes a few points on the grounding grid to measure the grounding resistance? Thank you~
For hazardous chemical enterprises, it is required twice a year, not once. Generally, the meteorological bureau is responsible for issuing the inspection reports; the cost is 60 yuan per testing site, and this applies to tall buildings, chimneys, key equipment, employee dormitories, etc
