How Do VFD Drives Work?
https://www.hiconics-global.co....m/how-do-vfd-drives-

Ⅰ. How does an inverter drive work : what are VFD drives?
How do vfds work? To know the answer to the question, you need to first understand what a VFD drive is. A vfd is used to control is a device used to control the power consumption of a motor. VFD can be used to reduce the energy that the motor needs for its operation. Variable frequency drives can change the speed and torque of the motor, which is achieved by controlling the power frequency of the motor. If we need to get a variable output from the motor, then we can use VFD device instead of any other mechanical devices.

Basically, a VFD is a motor driver that controls the speed, torque, direction, and horsepower of a motor. There are many speed drivers on the market that can be used to control the motor, but none have all the features of a VFD. Therefore, by using VFD, we can control the voltage and frequency supplied to the motor. VFD is also known as variable speed drive or adjustable speed drive, etc. It is also known as an inverter because it is able to change the frequency of the output voltage and current. Because of all these features, VFDs are widely used in HVAC systems. So how do VFD drives work?

Ⅱ. How do VFD drives work: their working process
What is variable frequency drive working principle? Typically, a motor consumes more current than its rated current when connected to a power source. The motor rotates at a synchronous speed, so VFD is used to change this speed, which is achieved by changing the frequency of the voltage applied to the motor. Therefore, when the VFD is connected to the motor power supply, it will start the motor at a low frequency and then gradually increase the frequency. VFD converts electrical energy into any form required to control the speed, torque, and direction of rotation of an AC motor. The rectifier section of the VFD converts alternating current into direct current. This rectified DC current is then transmitted to an intermediate circuit consisting of an inductor and a capacitor. After that, it is transferred to the inverter section, converting the direct current into alternating current with variable frequency and voltage. This is done with the help of pulse width modulated signals. The desired output is generated with the help of semiconductor switches, which commonly are IGBT.

Ⅲ. How do VFD drives work: their applications
What does an inverter drive do? Now we know the answer to it, but where is it used? VFD drives are used in the marine industries, for power generation and power positioning, and industries such as paper mills, steel mills, and cement plants, and they can also be used in the oil and gas industry for controlling pumps, compressors, turbines, and so on. VFD drives are used in HVAC systems, where they can be used in all variable torque applications, while for metallurgy, they can be used in power generation sections such as condensate pumps, forced ventilators, etc.

The Identification Method of Low Smoke Zero Halogen Power Cables
https://www.jenuincable.com/th....e-identification-met


Electrical Cable Identification Method
Since the raw materials of low smoke zero halogen power cables are more expensive than that of ordinary wires and cables, and in terms of the setting of the production machines, the production time of low smoke zero halogen power cables is about 30%-50% longer than that of ordinary wires and cables, which is relatively low in efficiency.

Therefore, the low smoke zero halogen cable price is about 10%-20% higher than that of ordinary cables. Some informal wire manufacturing companies sell low smoke zero halogen power cables at low prices, making customers be taken in. So it is necessary to learn how to identify low smoke zero halogen power cables, and the identification of low smoke zero halogen power cables mainly lies in the identification of insulating materials:

1. Combustion method

Judging whether the cables are flame retardant wires or flame retardant power cables according to whether they are easy to burn; Distinguishing their flame colors according to whether they burn; According to whether there is smoke and the amount of smoke to determine whether they are low smoke zero halogen power cables, and if there is smoke, distinguish the color of the smoke. For example, whether the smoke is clear smoke or the smoke containing carbon ash; whether there is molten glue dripping, and if so, whether the molten glue continues to burn and what kind of smell is produced when burning.

Teflon: It softens and deforms when exposed to fire, it has wrinkling thin layer, a small amount of coke and slightly coke smelling when burns, also it is incombustible.

PVC: It has green flame mask when burns and gives off white smoke with the smell of hydrochloric acid when softens. It is self-extinguishing plastic and will sink when placed in water.

PE: It burns with blue light mask, molten glue dripping as well as the smell of candles, and its burning area is molten transparent. Besides, it will float when placed in water.

PP: It burns with blue light mask, molten glue dripping as well as the smell of kerosene, and its burning area is molten transparent. Besides, it will float when placed in water.

PU: It gives off black smoke and drips molten glue when burns. Also, it has no scorch, no smell of nitrogen and oxygen compounds, but the property of prolonged burning.

Nylon: It burns with blue light mask and the smell of burning hair. It is molten material and has the characteristics of self-extinguishing.

Silicone category: It is tasteless and burns with thick white smoke and white residual ash. Also, it has the characteristics of self-extinguishing.

2. Hydrometry

Density comparison method is based on the density of water. Placing the plastic material in water, if it sinks, the density of the plastic is greater than that of water, while if it floats, the density of the plastic is less than that of water. This method can be used in conjunction with other methods.

The above two methods can easily test flame retardant power cables, flame retardant wires, low smoke zero halogen power cables as well as and low smoke zero halogen wires.

Difference between SVG and SVC
https://www.hiconics-global.co....m/difference-between

Different Working Principle
Static var generator wikipedia (SVC) working principle: svc capacitor can be regarded as a dynamic reactive power supply. According to the demand of the power grid, it can not only provide capacitive reactive power to the power grid, but also absorb the redundant inductive reactive power in the power grid. Usually, the capacitor bank in the filter connected to the power grid can provide reactive power to the power grid. The reactive power of these excess capacitive reactive power is absorbed by a shunt reactor.

High voltage svg working principle: SVG is based on a high-power voltage inverter. By adjusting the amplitude and phase of the output voltage of the inverter, or directly controlling the amplitude and phase of the AC side current, the required reactive power can be quickly absorbed or released, so as to achieve the purpose of fast and dynamic adjustment of the inverter. reactive power.

Response Speed
Generally, the response speed of static var compensator is 20-40ms; the response speed of svg static var generator is not more than 5ms, which can better suppress voltage fluctuation and flicker. Under the same compensation capacity, SVG has the best compensation effect on voltage fluctuation and flicker.

Low Voltage Characteristic
SVG has the characteristics of the current source, and the output capacity is less affected by the bus voltage. The advantages make SVG have great advantages when used for voltage control. The lower the system voltage, the need for dynamic reactive power regulation voltage, the low voltage characteristics of SVG, the output of reactive current has nothing to do with the system voltage and can be used as a controllable constant current source, the system voltage drops, the rated reactive current can still be output, and it has a strong overload capacity;

The output capacity is greatly affected by the bus voltage. The lower the system voltage is, the reactive current output capacity will be proportionally reduced, and there is no overload capacity. Therefore, the reactive power compensation capability of SVG has nothing to do with the system voltage, while the reactive power compensation capability of SVC decreases linearly with the decrease of system voltage.

Improved Operation Safety Performance
SVC uses silicon-controlled rectifiers to adjust reactance and multiple groups of capacitors as the main means of reactive power compensation, which is prone to resonance amplification, resulting in safety accidents. When the system voltage fluctuates greatly, the compensation effect will be greatly affected, and the operating loss will be large.

The SVG matching capacitor does not need to set up a filter bank, and there is no resonance amplification phenomenon. SVG is an active compensation device, which is a current source device composed of a shutdown device IGBT, which avoids the resonance phenomenon and greatly improves the operational safety performance.

Are Cross-linked Polyethylene Cables and Common Power Wires the Same?
https://www.jenuincable.com/ar....e-crosslinked-polyet


The cross linked polyethylene cable and the non-crosslinked polyethylene cable have many differences. The cross-linked polyethylene cable has good thermo-mechanical properties, excellent electrical properties and chemical resistant property. It has other advantages as well, such as simple structure, light weight and less limit to lay, which is extensively used as a new type of cable in urban power grid, mines and factories.

1. Difference in heat resistance

The non-crosslinked PVC is able to tolerate a temprature of 70℃, while the cross-linked polyethylene cable can bear more than 100℃.

2. Difference in scope of application

When it burns, the non-crosslinked polyethylene cable will release toxic smoke. When you need to keep a low level of toxicity during the process of fire prevention, you can't use PVC. The cross-linked polyethylene cable is applied to power grid, industrial unit or other large-capacity units, which is used to lay curcuits of AC 50Hz and rated voltage of 6kV ~ 35kV, mainly funtioning to transmit electric energy.

3. Differences in material

The cross-linked polyethylene is a kind of polyethylene which is converted from linear molecular structure into three-dimensional network structure by chemical or physical means. To a great extent, it improves the thermo-mechanical properties of polyethylene and maintains its excellent electrical properties.

The rated working temperature of the cross-linked polyethylene cable can reach 90℃, which is higher than the rated working temperature of the paper-insulated cable, the pvc insulated cable and the polyolefin-insulated cable, thus the carrying capacity of the cable is further improved.

Wire Materials, Basic Requirements and Types of Overhead Conductor
https://www.jenuincable.com/wi....re-materials-basic-r


The role of overhead conductors is to conduct current and transport electrical energy. The material of the wire must not only have good electrical conductivity, but also have sufficient mechanical strength and good shock and corrosion resistance, and it must be light in weight and highly cost effective.

Ⅰ. The material of overhead conductors

The materials of overhead conductors include copper, aluminum, steel, aluminum alloy, etc. Copper is a metal with very good electrical conductivity and can resist corrosion, but it has a large specificity and a high price, and its mechanical strength cannot meet the strength requirements of large spans. Copper is generally not used in current overhead transmission lines. The conductivity of aluminum is lower than that of copper, its weight is lighter, and its price is low. Under the condition of equal resistance value, the quality of aluminum wire is only about half of that of copper wire. But the disadvantage is that the mechanical strength is low, and after the formation of alumina film on the surface of the operation, the electrical conductivity is reduced and the corrosion resistance is poor, so the high voltage distribution line is used more. Generally, aluminum stranded wire is not used in transmission lines. Although steel has high mechanical strength, it has poor electrical conductivity, poor corrosion resistance, and is easy to rust. It is generally only used as a ground wire or pull wire, not a wire. Steel has high mechanical strength and aluminum has good electrical conductivity. There are several strands of steel wire inside the wire to withstand tension; the outside is multi-strand aluminum wire to conduct current. Due to the skin effect of alternating current, the current mainly passes through the outer layer of the conductor, which makes full use of the electrical conductivity of aluminum and the mechanical strength of steel, complementing each other and complementing each other. At present, almost all overhead conductors use steel core aluminum wire.
