How long has your oil sample been waiting to reach the lab?
Timing matters. When samples sit too long before analysis, their properties can shift, changing the story your data tells.

ASTM D923, section 17.2.1, calls for samples to reach the laboratory as quickly as possible.

Prolonged storage can produce two key changes:
🔹A decrease in fault gas concentrations
🔹An increase in atmospheric gases

For transformers with gassing problems, that lost data can directly impact the diagnostic.

Our latest Lab Talk explains how storage delays affect your results, complete with a real-world example.

AVO Diagnostic Services continues to expand our transformer oil testing capabilities.
Our Bensalem, PA lab now offers:
✅ISO 17025 accredited oxidation inhibitor content testing (ASTM D2668)
✅Particle count testing (ASTM D6786)

Oxidation inhibitor testing helps identify when insulating oil may be losing protection against oxidation and degradation. Particle count testing helps detect contamination levels that could indicate abnormal wear or the need for further evaluation.

With multiple labs now supporting these capabilities, customers can expect faster turnaround times and responsive testing support.

📝 Lab Talk: What Information Is Needed For A Reliable Analysis? 📝
Accurate transformer diagnostics depend on more than just the physical oil sample. To deliver the precise, reliable data you need to make confident decisions, we require specific context about your equipment.

A holistic approach to testing ensures we evaluate your results against the correct industry standards. To get the best analysis of your transformer oil, always provide the following information with your sample:

🔹 Nameplate Data: Supplying this foundational information allows our laboratory to establish the correct parameters for your analysis.

🔹 Serial Number: Tracking this unique identifier creates a unified history for your asset, helping us monitor trends and predict potential issues.

🔹 Equipment Type: Identifying the specific equipment type ensures we apply the appropriate diagnostic criteria and safety standards.

🔹 Sample State: You must indicate if the fluid is in service, reclaimed, or from new equipment to establish correct baseline metrics.

🔹 Liquid Type: Specifying the exact liquid type is essential, as we apply different diagnostic limits for each insulating fluid.

🔹 Rated Voltage (kV): Providing the rated kV ensures our evaluation accurately reflects the operational demands placed on your system.

Turn complex data into actionable insights with our diagnostic services. Contact AVO Diagnostics today to ensure your systems remain safe, reliable, and operational.

🧪 Lab Talk: Oil Sampling Tips 🧪
Accurate transformer diagnostics begin with proper oil sampling. Even small mistakes during collection can impact results, leading to unreliable data. Use these expert tips to make sure your samples truly represent your transformer’s condition:

🔹 Follow ASTM D923
This industry standard outlines proven sampling practices that help ensure oil samples truly represent transformer conditions.

🔹 Avoid sampling on humid days
Transformer oil readily absorbs moisture from the air. High humidity can artificially elevate moisture readings before the sample even reaches the lab.

🔹 Use a glass syringe for moisture & DGA
Glass syringes preserve dissolved gases and prevent atmospheric contamination. Bottles don’t replicate the sealed environment inside a transformer.

🔹 Clean and flush the sampling valve
Stagnant oil and debris in the valve can contain excess moisture and particulates that don’t reflect the active oil in service.

🔹 Flush sampling containers
Even new containers may hold residual moisture or contaminants that can affect sensitive tests.

Why it matters:
Reliable sampling leads to accurate diagnostics, fewer false alarms, and better asset decisions.

Are you certain your oil samples are prepared and shipped correctly? Oversights at this stage can delay results and lead to incomplete diagnostics.

Here’s how to ensure every sample reaches our lab in optimal condition:
📝 Complete one AVO Diagnostic Sample Data Sheet for each piece of equipment.
🔒 Securely close syringe valves and tightly seal all bottle caps.
📦 Pack the box securely to protect samples, ensuring it’s not overpacked or overweight.
🚫 No need to tape/write on syringe boxes.
