About Transformer Oil Testers

Since most machineries from simple car engines to huge transformers rely on oil to maintain peak efficiency, it's extremely important to regularly test that oil has the correct properties.

In its most basic form, crude oil is not a useful product. By the use of several techniques such as distillation, the crude oil is broken down into a range of useful by-products, including common petroleum used in car engines, plastics, and transformer oil.

Oil is particularly important in transformers where it acts as a form of insulation, to suppress both corona and arcing. It also acts as a coolant to stop the transformer from overheating. As both corona and electrical arc discharge can be extremely damaging to the overall efficiency of a machine (and humans), these suppressing measures are vital for high-voltage equipment.

Transformer Oil Changes and Becomes Contaminated

As a result of electrical and mechanical changes, oil's general efficiency also changes over time when used in products such as transformers. There's also a significant chance of the oil becoming contaminated by chemical reactions between the oil, high temperatures, and electrical components, meaning that regular checks on the performance of oil must be taken. Without these tests in place, oil rapidly loses its ability to work correctly, rendering your machinery useless until it is repaired. It can be stopped by simply testing the oil, and assessing whether it needs to be replaced, filtered, or regenerated.

As oil has to be broken down into very specific forms such as transformer oil, making sure it is still in the correct form is an essential process. The electrical properties of the oil can suddenly change due to changes in oxidation, acids, sludge gas, and even water absorption, so that's why it's essential to regularly test oil samples for substances that shouldn't be present. To do this, you'll need an oil test set.

Oil Test Kits for the Analysis of Mechanical and Insulation Oil

By feeding a small sample of the oil you're working with into an oil tester it can be analyzed extensively, providing you with information about what's exactly inside the oil you're testing. Samples are generally taken from machinery over some time to assess general wear and tear, as the presence of contaminants and 'wear debris' from the machinery can indicate the machine's overall condition. During the transportation of samples, it's extremely important that they're safely secured, as contamination can take place as the oil is moved from the machine to the oil testing kit.
