Industrial firms often use a wide range of tools and machines to control the quality and flow of the current so that they can use it for their diverse purposes. One such device is the line reactor, a choke, a VFD, or a variable frequency drive accessory. It has a wire coil inside it. It helps to create a magnetic field when the current moves through it.
The magnetic field can limit the rising of current and reduce the harmonics so that the drive is protected from potential power surges and transients. The two main types of reactors used in drives with variable frequencies are AC and DC reactors.
The AC reactors are typically placed between the drive and the power system and are commonly termed the AC line reactor. On the other hand, the DC reactor is also known as a DC link reactor when it’s placed inside the DC link of the variable frequency drive.
The function of the DC and AC reactors is to limit the harmonic currents. Since the AC reactors are placed between the primary power system and incoming power terminals of the drive, they are better suited to protect the whole VFD from potential power transients and power system surges.
The reactors are built sturdily to prevent overvoltage trips and increase the life span and reliability of the VFD. They can also boost the total power factor and minimize the chances of nuisance tripping. It is factors like these that make AC reactors indispensable for the industry. When you invest in a high-end AC reactor offered by a leading company of AC reactor manufacturers, you can ensure that the whole power system functions more smoothly. The AC reactor can come in handy if the voltage of the network current is seriously distorted.
The AC reactor has got a coil wrapped evenly around its steel core. One of the reasons why it is highly recommended to use the AC reactor is that it can boost the functioning of the device’s input power factor and allows the inverter power supply to operate smoothly. In this way, harmonics can be reduced to eliminate external conflicts. The AC reactor can help reduce the harmonic distortion or the noise on the input AC. It can reduce the maximum amplitude of the input sharp spine.
The DC Bus can be stabilized by reducing the harmonics, and it can boost the lifespan and functioning of the capacitor. The AC reactor serves as a filter and protects the system’s input rectifier circuit system from spiky pulses and noises resulting from switching on and off of the other inductive loads. Sometimes, the current reactor can be utilized with the drive’s output side for the low-inductance motors. However, this is typically not required due to the advanced design and reliable performance of insulated-gate bipolar transistor (IGBT) technology.
The AC reactor can be utilized for a broad range of functionalities as considered indispensable for the industrial environment. For instance, the AC reactor can help to protect industrial electrical equipment and enhance its lifespan significantly. These reactors are known to deliver reliable results when it comes to the capacitor protection function and the preservation of the switchgear.
The AC reactors can work together with the capacitors to help get rid of the harmonic components responsible for enhancing the quality of the electricity used in the system. Harmonic filter inductors are required for instances when the voltage and the system current have become distorted. Last but not the least, AC reactors can be used to protect the inverters.
