Scope

Scope: This document specifies a method for determining ionic impurities in insulating paper used for the valve side bushings of ultra-high voltage converter transformers by ion chromatography. This document is applicable to the determination of ionized water-soluble organic or inorganic ionic impurities in insulating paper used for the valve side bushings of ultra-high voltage converter transformers, including bromide (Br-), chloride (Cl-), fluoride (F-), nitrate (NO3-), nitrite (NO2-), phosphate (PO43-), sulfate (SO42-), ammonium (NH4+), calcium (Ca2+), lithium (Li+), magnesium (Mg2+), potassium (K+), sodium (Na+), acetate (CH3COO-), adipate (OOC(CH2)6COO-), formate (HCOO-), malate (OOCCH2CH(OH)COO-), methanesulfonate (CH3SO32-), succinate (OOC(CH2)2COO-), and phthalate (OOC(C6H4)COO-). The detection of ionic impurities in other insulating materials and other water-soluble ionic impurities can also be performed by referring to this document.
