Almost all the electrical engineers already know what a line reactor is and how it helps the variable-frequency drives. Here, I have discussed a little more about the line reactors focusing on why most engineers use and recommend line reactors.
Following are all the main reasons why
- It is easy to add them to an existing VFD
- They deliver surge protection to the VFD
- They increase the reliability and durability of the VFD
- They offer nominal protection against overvoltage tripping
- Line reactors are a cost-effective solution for a reduction in harmonic distortion
- They provide some level of buffering against voltage spikes
- They are better to compliance with utility standards
- They help to avoid litigation and settle damages
- They help in reducing high-frequency noise made in a power system
- They improve true power fact
- They help to reduce cross-talk occurs between drives
- They help to prevent circuit breakers and fuses from tripping or blowing caused by high current spikes
- They provide required impendence between power system capacitors and VFDs
- They protect capacitors and other components from harmonic resonance in the power system
- They reduce current levels and free up the capacity of the system
- They help to reduce irregular problems and faults caused due to unidentified reasons
There are some manufacturers who can provide you with not just the line reactors but also all types of them including grounding reactors, smoothing reactors, damping reactors, current limiting reactors, shunt reactors, and so on. However, it is important to choose a manufacturer who guarantees to provide quality power reactors regardless of the application.
Key Features of the reactors provided by a quality manufacturer
- From low voltage to 1100kV AC & DC applications
- Built to ISO 9001 & 14001 quality standards
- In full compliance with ANSI/IEEE, IEC, and all other international standards
- Supported by in-house wire & cable manufacturing
- All winding fully encapsulated with a combination of fiberglass and epoxy resin
- Highest mechanical & short circuit withstand capabilities
- Highest voltage withstand
- Lowest noise levels can be achieved
- Easily installed for both indoor or outdoor applications
- Least maintenance required
Supportive structure
All the reactors can manufacture with supportive structures made of fiberglass or steel. This ensures a rise of each unit to the sufficiently safe height for human clearance while providing enough magnetic clearance between the ground and the reactor. These support structures are usually customized based as per the engineering aspects and designed according to the overall weight of the reactor so that not to exceed the dimensions and shipping costs.
There are manufacturers which are capable of making quality power reactors as per the application requirements. Most of them can also ship the equipment to the buyers at a nominal shipping cost. Apart from that, most manufacturers also take orders online considering the utmost level of convenience of the buyers.
