To test an oil burner transformer, first ensure that the power is disconnected for safety. Use a multimeter to check the primary voltage of the transformer by measuring the incoming voltage at the primary terminals; it should match the specifications indicated on the transformer label. Next, test the secondary voltage by measuring across the secondary terminals; it should also align with the expected output voltage. Additionally, inspect for any physical signs of damage such as burned wires or corrosion. Finally, verify continuity through the transformer windings ensuring there are no open circuits present. By following these steps, you can effectively assess the functionality of the oil burner transformer and identify any issues that may require your attention.

Askarel is not actually oil but a synthetic, non-flammable liquid that was historically used as an insulating fluid in transformers and capacitors. Askarel is a trade name for a group of polychlorinated biphenyls (PCBs), which were used because of their excellent fire-resistant properties. However, due to their environmental toxicity and potential health hazards, the use of Askarel and other PCB-based insulating fluids has been banned or heavily restricted in many countries.

The different types of transformer oil include:

Mineral Oil: The most commonly used type, derived from petroleum, known for its good insulating properties and thermal stability.
Silicone Oil: Used in environments with high temperature variations due to its excellent thermal stability.
Natural Ester Oil (e.g., FR3): Biodegradable and environmentally friendly, made from vegetable oils, and offers superior fire resistance.
Synthetic Ester Oil: A synthetic alternative to natural esters, providing similar benefits with enhanced performance in extreme conditions.
PCB Oil: Once widely used but now banned or heavily restricted due to its toxicity and environmental impact.
