Get grounding resistance measurement in Haiphong

Earthing system plays a very important role in the neutralization of the lightning, ensuring effective protection of lightning protection systems. The system's equipment includes pile pot with copper clad steel grounding, copper lightning and chemical drainage reduces soil resistance. To connect the grounding copper deposit and copper wire to escape the lightning, we use thermal chemical welds. Weld power diversion effect (better than wire), not aging, corrosion in a long time. Reduced chemical resistance are mixed with each other in the areas of water and pour up to bury the electrodes to create a uniform hardened layer. This chemical will be effective in reducing low-resistance grounding system; not washed away and sustainable (not require maintenance) for many years; Grounding system helped pile against corrosion of the natural environment. Reduced chemical use and soil resistance welding heat turned, the grounding system must ensure lightning protection factor has more than 10 Ohm low impedance for direct lightning and less than 4 Ohm for the Surge Protection.

Thus, in order to maintain and ensure the safety of the lightning protection system must be measured earthing resistors, in terms of state management in this field stipulated in Article 7 of Decree No. 79/2014 / ND CP of the Government dated 07.31.2014. Accordingly, the basis of dangerous explosives specified in Annex II attached to this Decree must have lightning protection systems to ensure the safety of fire prevention and fighting and according to National Standards ISO 9385: 2012 "lightning protection for buildings - guide to design, test and maintenance of the system," the lightning protection system checks are conducted periodically, preferably not more than 12 months
