Some specific properties of insulating oil should be considered to determine the serviceability of the oil.

The properties (or parameters) of transformer oil are:

1. Electrical properties: Dielectric strength, specific resistance, dielectric dissipation factor.
2. Chemical properties: Water content, acidity, sludge content.
3. Physical properties: Interfacial tension, viscosity, flash point, pour point.

 

Transformer Oil Testing

Transformer oil needs to be tested to ensure that it works for today's standards. Testing standards and procedures are defined by various international standards, and most of them are set by the ASTM.Oil testing consists of measuring the breakdown voltage, and other chemical and physical properties of the oil, either through portable test equipment or in a laboratory. Through proper testing, the transformer's lifespan is increased, reducing the need to pay for replacement.
