Oil Sample Analysis

Oil Sample analysis is used to determine the dielectric condition of your electrial system's components. Oil sample analysis is important to your electrical system's components because oil wears down and collects all the contaminants in your system. If a thermal or electrical fault develops both dieletric and solid insulation may partially decompose. Often, an analysis of the oil can help determine which part of your transformer needs maintenance, repair, or replacement.

Some benefits include pre-emptive fault detection, identification of deteriorating conditions, reducing unplanned downtime, prioritizing maintenance schedules, maximizing warranty benefits, and identifying problems early.

What We Measure with Oil Analysis

We do a substantive analysis of your component's oil including the following:

Dissolved Gas Analysis (ASTM D-3612)

  • Hydrogen
  • Methane
  • Ethane
  • Ethylene
  • Acetylene
  • Carbon Monoxide
  • Carbon Dioxide
  • Nitrogen
  • Oxygen

Oil Screen Analysis

  • Moisture in Oil (D-1533B)
  • Interfacial Tension (D-971)
  • Acid Number (D-974)
  • Color Number (D-1500)
  • Visual Exam (D-1524)
  • Dielectric Breakdown (D-877)
  • Dielectric Breakdown 1 mm (D-1816)
  • Dielectric Breakdown 2 mm (D-1816)
  • Power Factor @ 25°C (D-924)
  • Power Factor @ 100°C (D-924)
  • Specific Gravity (D-1298)
  • Passivator (WDS)
  • Oxidation Inhibator (D-2668)

Diagnostics on all of the above analysis
