Typical Wiring Diagram of 35kV Line Radial π Connection

When a 35kV line adopts a radial power grid structure, a single - side power supply or a double - side power supply radial type can be used according to the situation of the power supply points, and a loop - out interval is reserved at the end of the line.

For double - radial lines, it is advisable to select a double - side power supply. When the power supply points do not meet the requirements, a same - side power supply can be adopted.

When the upper - level power supply points do not meet the requirements for constructing a chain - type structure, a loop - type can be used as a transition structure for the chain - type structure.

In areas with high load density such as downtown areas and urban districts, as well as areas with high requirements for power supply reliability, chain - type wiring can be adopted.

Analysis of the Principle of Second - harmonic Restraint for Overcurrent Protection of Distribution Automation Switches

Substance of Second - harmonic Restraint in Overcurrent ProtectionThe substance of second - harmonic restraint in overcurrent protection is to use the second - harmonic component to judge whether the current is a fault current or an excitation inrush current. When the percentage of the second - harmonic component to the fundamental - wave component is greater than a certain value, it is judged to be caused by the excitation inrush current, and the overcurrent protection is blocked.Therefore, the

Why are the ground fault point and the accident point not at the same location?

Why are the ground fault point and the accident point not at the same location?

Fault Transfer VoltageIn low - voltage distribution systems, there is a type of personal electric shock accident where the accident occurrence point and the system fault point are not at the same location. This kind of accident occurs because after a ground fault happens elsewhere, the generated fault voltage is conducted to the metal casings of other equipment through the PE wire or PEN wire. When the fault voltage on the metal casing of the equipment is higher than the human - body safe voltag

What is reactive power measurement?

What is reactive power measurement?

The power which exists in the circuit when the voltage and current are out of phase to each other, such type of power is known as the reactive power. The formula measures the reactive power in the circuitReactive Power Measurement & VarmetersReactive power measurement is critical as it indicates circuit power loss: low reactive power worsens load power factor, increasing system losses. Varmeters (volt-ampere reactive meters) measure reactive power and are categorized by circuit phases:Single
