Product Detail

Overview

YSF series pressure relief valve mainly applied to oil-immersed transformers. It can to load tap changer and other oil- immersed electric equipments. Good protective performance. When the inner pressure raches the setting value, it can be opend and closed automatically and the pressure in the will keep normal. It is used as protective to avoid accidents when the pressure in the tank is very high.

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
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

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.
