Voltage Loss What is the difference between voltage offset and voltage drop

Define the domainDifferent; 2 The voltage drop is a vector, and the latter two are algebraic differences; 3. Voltage drop|Loss is the relationship between voltages at any two points of the power grid, and voltage offset is the relationship between voltages at any point in the power grid.

4. The voltage loss is the longitudinal component of the voltage drop [110kV] in the approximate calculation, and the voltage loss reflects the first and last electricity.

So-called"Voltage loss", which refers to the difference between the modulus of the voltage at the head of the transmission line and the modulus of the voltage at the end. u loss = 丨u1丨-丨u2丨.

So-called"Voltage offset", which refers to the actual voltage and rated voltage of the network.

value.

Voltage offsets also have numerical values and are often expressed as percentages.

The main causes of voltage drift are: system voltage loss caused by system lagging reactive load and line loss.

Voltage loss refers to the voltage drop caused by the length of the line or a large load, and the voltage on the supply side is significantly different from the voltage on the load side.

Voltage offset refers to how much it deviates from 220V, which may be large or small.

Voltage drop is similar to voltage loss, both are below 220V, and there are other uncertainties caused by voltage drop that are different from losses.

The voltage drop is a vector, and the latter two are algebraic differences; Voltage Drop |Loss is the relationship between voltages at any two points of the power grid, and voltage offset is the relationship between voltages at any point in the power grid. The voltage loss is the longitudinal component of the voltage drop in the approximate calculation.

It can't be avoided. How to reduce: Breakdown of electrical equipment insulation before Mingzhen, actual voltage and rated voltage.

The difference is called voltage offset, and the large load fluctuations that affect the electric furnace output of the steel mill, shorten the life of electrical equipment, and have an impact on the power system.

The normal operation of the equipment itself is also very unfavorable.

3: The generator reduces the output, and the impact of impact or intermittent load changes will also cause voltage fluctuations and voltage excursions.

The voltage offset is too large (either high or low).

2. Causes of voltage offset.

Because the power supply line itself has a certain impedance.

Common effects. The long change cycle damages the equipment and power system, so that the actual voltage of different places on the power supply line is different, which will not only affect the quality and output of industrial and agricultural production products, so it will produce voltage offset, shorten the service life of the motor or burn out1, and the voltage drop will be generated by the current.

Voltage drop Voltage loss.

The voltage loss is related to the wire material, wire cross-section, length, and load current. Its relationship:

Voltage loss: u ri

Line resistance: r l s

Wire resistivity, copper wire: , aluminum wire: , l wire length: m, s wire cross-section: m ).

I don't think so, the voltage loss is a percentage value, we generally count it as no more than 5%, and the voltage drop is a specific voltage value, if I remember correctly, it seems that the voltage drop = voltage loss.

Voltage loss = voltage drop.

Voltage loss: Refers to the numerical difference between the voltages at the two ends of the impedance element in the circuit. In engineering calculations, a voltage loss is equal to a voltage drop.

Voltage drop: When the current passes through the electrical device (resistance), the potential difference (potential difference) generated by the two ends of the device is called the voltage drop. In engineering calculations, the voltage drop is equal to the voltage loss.

The so-called voltage offset generally refers to negative offset, that is, voltage loss. It refers to the percentage of the voltage offset value at the beginning and end of the line to the rated voltage value of the line, that is.

u％=(u1-u2)／ue×100％

where u1: voltage at the beginning of the line (v);

u2: end-of-line voltage (v);

UE: Line Rated Voltage (V).

The so-called "voltage offset" refers to the difference between the actual voltage of the network and the value of the rated voltage. Voltage offsets also have numerical values and are often expressed as percentages. The main causes of voltage drift are:

System voltage loss caused by system lag reactive load and line loss.

Voltage offset is the difference between the actual voltage and the rated voltage.

The "voltage" that is often referred to should be called the "potential difference" strictly speaking, which indicates the difference in the potential of two points in the circuit. However, when the current passes through an impedance load, the potential decreases, referred to as "voltage drop". When an electric current passes through a power supply (electromotive force), the potential rises, referred to as "electric potential rise".

So the "voltage drop" is relative to the "potential rise".

The so-called voltage offset, generally copy refers to negative offset, that is, voltage loss. It refers to the percentage of the voltage offset value at the beginning and end of the line to the rated voltage value of the line, that is.

u％=(u1-u2)／ue×100％

where u1: DAO voltage (V) of the initial state of the line;

U2: Electrical width and closed-sensitive voltage at the end of the line (V);

UE: Rated voltage (V) of the line Shenzhi Road.

Voltage offset is the difference between the actual voltage and the rated voltage.
