Using Flexible Aluminium Bottles for Accurate DGA
Based on IEC 60475:2022
TriboTech ApS
Purpose: Ensure oil samples remain representative for Dissolved Gas Analysis (DGA) to assess transformer health. Always wear PPE and follow site safety protocols.
Clean equipment; connect tubing to sampling valve
Open valve slowly; let 1-2L flow laminarly to waste (no bubbles)
Fill bottle 1/3, discard to waste
Fill from bottom with laminar flow; overflow ~2 volumes
Remove tubing (oil flowing); squeeze sides; cap tightly
Close valve; label sample; retighten cap after cooling
OEM Alignment: Procedures should always align with the transformer manufacturer's (OEM) specific maintenance instructions.
Safety Protocol: Strict adherence to site-specific safety protocols and PPE requirements is mandatory and supersedes this guide.
IEC Reference: This guide is a simplified visual summary based on IEC 60475:2022 (Method of sampling insulating liquids). It is not a substitute for the comprehensive standard.
