Transformer oil sample bottles typically contain a sample of insulating oil taken from a transformer or other electrical equipment for analysis. The contents of the bottle include the following:
Volume Capacity: - 1 Litter, 2 Litter and Above Capacity.
1. Transformer Oil:
The oil sample is typically about depending on the testing requirements and the size of the bottle. This oil is a dielectric fluid that serves as an insulator and coolant in transformers.
2. Air Gap or Space:
The bottle is not filled completely to allow for thermal expansion of the oil and to prevent pressure build-up during transportation.
3. Contaminants (if any) :
Depending on the condition of the transformer, the sample might contain impurities such as moisture, dissolved gases, solid particles, or degradation products like sludge and acids.
4. Labelling Information:
The bottle should have proper labeling that includes:
- Sample ID
- Date and time of collection
- Transformer or equipment ID
- Sampling location
- Collector's details
- Any special handling instructions (if required)
Types of Tests Conducted on the Oil Sample:
- Dissolved Gas Analysis (DGA) to detect fault gases.
- Moisture Content to measure water contamination.
- Dielectric Strength to check the oil's insulating property.
- Acidity Test to assess oil degradation.
- Furan Analysis to gauge paper insulation condition.
Proper handling, cleanliness, and sealing of the sample bottle are critical to ensure accurate test results.
