Engineering AllOther (1379) what is the use of providing earthing for tanks? i know for lightning we use earthing ? Here one of my ONGC project there is no need of lightning protection and there is no power connection near by tank in that situation also ONGC asking earthing for tanks but we didn't understanding why they asking earthing? is anybody tell exact answer?

2088we have 2 O2/Comb Analyzers Servomex Model 2700 in service for one of the furnaces in our chemical plant. It is giving High Temperature Alarm. Checked Temperature and found it to be 800 Deg C whereas Set Point is 700 Deg c. It is strange why is temperature not at SP. Also response is 23 % with 21 % Inst Air and with N2 reading is not coming down. please clarrify this issuses very urgent
