  According to what basis? Is there a national standard?   Density relay detection practice   1, detection cycle and testing requirements   According to the provisions of the national standard and industry standards, SF6 electrical equipment testing cycle and requirements are as follows:   1) The new SF6 electrical equipment is required to carry out gas density relay detection.   2) on the operation of the sf6 gas density monitor detection cycle is defined as: handover, the operation of 1 to 3 years, after overhaul, if necessary.     3) gas density relay action value, should meet the technical requirements of the product or according to the manufacturer. The error of the indication value of the pressure gauge and its variation shall be within the allowable error range of the corresponding grade of the product.   There are a lot of foreign products related to the contents of this manual, as every 5 to 10 years of maintenance...
