Inductors: 5 Parameters to Consider While Buying Inductor

No matter if you are looking for a high-current inductor or a low current inductor, having a guide of what parameters you should consider while making a purchasing can be very helpful. But, before taking a look at these parameters, it is best to discuss a bit about inductors for those who are new to this device.  What are Inductors? In simple words, inductors are components with two terminals, used for filtering, timing, and power electronics applications. As long as current flows in the device, they store energy in the form of the magnetic field. Their tendency is to oppose the change in current by inducing electromotive force, i.e., e.m.f., as per Lenz’s law. It can be used as an open circuit for AC signals and a short circuit for DC signals. The inductance value is represented with the SI unit - Henry (H).  Factors that Affect Inductance There are four factors that affect the value/amount of inductance in inductors, including: • Number of turns in the coil

Air Core Inductor and Its Key Advantages

Air core Inductor is a kind of inductor that does not depend upon a ferromagnetic material to achieve its specified inductance. The inductor has only air inside when it comes to windings upon a different insulator such as bakelite, glass or PTFE etc. What is an inductor?  It is a kind of a passive two-terminal electrical component which stores electric energy in the form of magnetic energy. The inductor uses a conductor which is attached to the coil and generates a magnetic field when electricity is flown into the coil from the left to right. Inductors are mainly used to block AC and allow DC to pass. Which is why they are also called chokes. They can also be used in some electric filters to separate signals of different frequencies, and in combination with capacitors to make tuned circuits, used to tune radio and TV receivers. Inductor blocks only AC because it only resists the change in current. There are different types of inductors. The ones whose core is fille

The Essential Use of Reactors in Substations

Image
A reactor is actually a coil with having several turns and much greater ohmic resistance value. Electrical Reactors are typically used to limit the short-circuit currents which can potentially cause damage to some equipment of the power system. The additional reactance which is added in series in order to protect the system is called reactors. A current limiting reactor is just another type of it which limits the heavily flowing current through other sections. This way, in case of issues we can simply isolate the faulty section instead of shutting down the entire power system. Reactors in substations are used for two main reasons : •      For lightly loaded substations connected to the end of long, high-voltage, transmission lines, the voltage may turn out to be unnecessarily high because of the Ferranti Effect. A shunt reactor can be utilized (exchanged online) to assimilate a bit of the reactive power produced by the appropriated capacitance of the transmission li

Everything You Didn’t Know About an AC Line Trap

Image
Have you ever wondered how these huge powerhouses are working to provide us the electricity supply 24X7? You must have seen different sized transformers, electricity poles, and other huge electric wireline arrangements. The electricity that comes to our homes reaches us traveling a long way going through different electrical components and line trap is one of the most significant among them. The AC line trap is actually a form of ‘parallel resonant circuit’ which is generally tuned to the carrier energy frequency. A parallel resonant circuit usually has high impedance at the frequency it is tuned with, therefore makes most of the carrier energy to flow nicely toward the remote line terminal. Whereas, the line trap’s coil offers a low impedance path for the power frequency of energy to flow well. As the power flow may get large at times, the coil used in a line trap should also be large in size. Hence a line trap is inserted between the connection of a coupling ca
