Analysis of Partial Discharge Principle (1)
Analysis of Partial Discharge Principle (1)
Analysis of Partial Discharge Principle (1)Under the action of an electric field, in an insulation system, discharge occurs only in some regions and does not penetrate between the conductors with the applied voltage. This phenomenon is called partial discharge. If partial discharge occurs near a conductor surrounded by gas, it can also be called corona.Partial discharge can occur not only at the edge of a conductor but also on the surface or inside an insulator. The discharge occurring on the su

What are the differences between HVAC and HVDC?
What are the differences between HVAC and HVDC?
Difference Between HVAC and HVDCElectricity generated in power plants is transmitted over long distances to electrical substations, which then distribute it to consumers. The voltage used for long-distance power transmission is extremely high, and we will explore the reasons for this high voltage later. Additionally, the transmitted power can be in either alternating current (AC) or direct current (DC) form. Therefore, power can be transmitted using either HVAC (High Voltage Alternating Current)

What are the Advantages of HVDC over HVAC?
What are the Advantages of HVDC over HVAC?Electricity travels long distances before reaching consumers. Power plants, often remote, supply electricity through hundreds of miles and multiple substations. High-voltage transmission reduces line losses, with both AC and DC used. Though AC is familiar via utility poles and home outlets, HVDC offers unique advantages in power transmission.The goal of power transmission is to minimize losses and costs. While both face influencing factors, HVDC has more

Is the neutral - point grounding method of the power grid of 110kV and above only the neutral - point direct grounding method？
Neutral - Point Grounding Modes and Protection of Transformers in Power GridsFor systems ranging from 110 kV to 500 kV, an effective grounding method shall be adopted. Specifically, under all operating conditions, the ratio of zero - sequence reactance to positive - sequence reactance X0/X1 of the system should be a positive value and not exceed 3. Meanwhile, the ratio of zero - sequence resistance to positive - sequence reactance R0/X1should also be a positive value and not exceed 1.In 330 kV a
