What is the difference between a dielectric and an insulator?

What is the difference between a dielectric and an insulator?

Dielectrics and insulators are distinguished primarily by their applications. One of the main differences is that a dielectric can store electrical energy by becoming polarized in an electric field, whereas an insulator resists the flow of electrons to prevent current conduction. Other key differences between them are outlined in the comparison chart below.Definition of DielectricA dielectric material is a type of insulator that contains few or no free electrons. When subjected to an electric fi

Fault Analysis and Treatment of Oil-Immersed Transformers

Fault Analysis and Treatment of Oil-Immersed Transformers

Oil Leakage at Welded JointsOil leakage at welded joints primarily stems from poor welding quality, such as incomplete or detached welds, and defects like pinholes and gas pores. Although oil-immersed transformers are initially coated with solder and paint during manufacturing, potentially masking these issues temporarily, the defects tend to surface during operation. Additionally, electromagnetic vibration can cause weld cracks, leading to oil leakage.To resolve such leaks, the first critical s

What losses occur during operation of the transformer? How to reduce losses?

What losses occur during operation of the transformer? How to reduce losses?

Transformers experience various types of losses during operation, primarily categorized into two main types: copper losses and iron losses.Copper LossesCopper losses, also known as I²R losses, are caused by the electrical resistance of the transformer windings—typically made of copper. As current flows through the windings, energy is dissipated in the form of heat. These losses are proportional to the square of the load current (I²R), meaning they increase significantly with high

Cable Fault Detection, Testing, Location and Repair

I. Methods for Cable Testing and Inspection:Insulation Resistance Test: Use an insulation resistance tester to measure the insulation resistance value of the cable. A high insulation resistance value indicates good insulation, while a low value may suggest insulation problems requiring further investigation.Voltage Withstand Test: Apply a high-voltage test using a high-voltage tester to verify whether the cable can withstand high voltage under its rated operating conditions. Under normal circums

Cable Quality Inspection and Cable Detection & Testing

Cable Quality Inspection and Cable Detection & Testing

Power cable quality inspection and cable testing are conducted to ensure that the cable's quality and performance meet specified requirements, thereby guaranteeing the safe and stable operation of power systems. Below are some common contents of power cable quality inspection and cable testing:Visual Inspection: Check the cable surface for physical defects such as damage, deformation, or scratches to ensure the cable's exterior is intact.Dimensional Measurement: Measure dimensional parameters su

Transformer Detection, Testing, Maintenance and Servicing

Transformer testing, inspection, and maintenance are essential tasks to ensure normal operation and extend the service life of transformers. Below are some recommended steps:Visual Inspection: Regularly inspect the transformer's exterior, including the enclosure, cooling system, and oil tank. Ensure the enclosure is intact, free from corrosion, damage, or leakage.Insulation Resistance Testing: Use an insulation resistance tester to check the transformer's insulation system. Verify that the insul
