The typical sample size or dimensions that a breakdown voltage (BDV) tester for oil can accommodate can vary depending on the specific design and capabilities of the instrument.
Here are some general guidelines:
Sample Volume:
BDV oil testers typically accommodate sample volumes ranging from 100 mL to 500 mL.
This allows for testing of small to medium-sized oil samples, which is suitable for most routine testing and quality control applications.
Sample Depth/Thickness:
The sample depth or thickness that can be tested is usually between 2 mm to 6 mm.
This range ensures a sufficient volume of oil for the test while maintaining appropriate electrode spacing and uniform electric field distribution.
Sample Diameter:
The sample diameter that can be accommodated by BDV oil testers is typically between 50 mm to 100 mm.
Larger diameter samples may be possible, but this depends on the specific design and dimensions of the test chamber.
Test Chamber Size:
The overall size of the test chamber or cell in a BDV oil tester is often designed to accommodate the typical sample sizes mentioned above.
The chamber size may range from approximately 100 mm x 100 mm to 150 mm x 150 mm, depending on the manufacturer and model.
It's important to note that some specialized or customized BDV oil testers may be able to accommodate larger or different sample sizes based on the specific requirements of the application or industry. Additionally, certain standards or guidelines, such as those from organizations like ASTM or IEC, may specify the recommended sample size or dimensions for BDV testing of insulating oils.
When selecting a BDV oil tester, it's important to consider the sample size and dimensions required for your specific application and ensure that the instrument is capable of handling the necessary sample sizes.
