Dissolved Gas Analyzer
ADGA-11

Product Overview

ADGA-11 is a system that can monitor and verify the condition of transformer through the analysis of oil vapor of insulating oil. It analyzes specific gas generated during abnormal operation of transformer and diagnose transformer condition early based on composition and amount of evolved gas through online analysis system. Gas extraction is based on Membrane / Vacuum method. Gas analysis uses the most accurate GC method and online operation is automatic independent operation up to 6 months and data storage and reading are possible.
In addition, it provides functions to prevent problems such as Auto Calibration function by comparing with existing calibration value and automatic scheduling function for each step alarm.
