Head Space TOGA Analyzer
The Touch Screen GC System Model Dhruva S2TS (NTPC & ERDA Approved) is configured For Dissolved Gas Analysis of transformer oil. It Can Be Built To Meet The Specification / Standards As Per ASTM D 3612 Section A or C or IEC 60567, 2005 Section 7.3 or 7.5 as required by the user.
This equipment can be used to detect the incipient fault in the transformer and arrest deterioration/damage to the transformer insulation by analyzing gases dissolved in the transformer oil and adopt preventive measures.
Gas Chromatography method is used for detection for the dissolved gases and identification of incipient faults. The most significant gases generated by decomposition of oil deterioration, of paper insulation on the conductor are hydrogen, methane, ethane, ethylene, acetylene, CO , Carbon di-oxide, Oxygen & Nitrogen. The quantities of these gases dissolved in transformer oil vary depending upon the type and severity of fault condition such as arcing, partial discharge, overheating, low-high temperature hot spot etc.
The process involved is separation, identification and quantitative determination of gases.The Dhruva S2TS analyzes the fault gases in a single injection with gases analysed depending upon user ordering.
