Non-linear resistors are those types of resistors where the electric current flowing through it changes with the exchange in applied voltage or temperature and does not change according to Ohm’s law.These serve as over-voltage protection for the devices.
Positive temperature coefficient, or PTC, describes how, in such devices, resistance rises as temperature rises. These shield the electronics from excessive current.When you say something is non-linear, you’re saying it doesn’t develop or progress logically from one stage to the next.
Instead, it alters abruptly or appears to move in multiple directions at once.Transistors, various semiconductor devices, vacuum tubes, iron core inductors, and transformers are examples of nonlinear elements.
Properties of Non-Linear Resistors:A non-linear resistor in general has a V-I characteristic which is not symmetric about the origin of the V-I plane.Non-linear resistor can produce harmonics in a circuit.In general, the non-linear resistors hold neither homogeneity property nor additive property.
Global non-linear resistors market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
METROSIL INTRODUCES NEW RANGE OF DE-EXCITATION NON-LINEAR RESISTORS.The “Metrosil 8000 Series” of De-Excitation Units, which are intended to safeguard large electrical generators, has just been launched, according to the market leader in silicon carbide non-linear resistors (also known as varistors).
The revolutionary 8000 Series (protected by Registered Design) was built around a better ergonomic structure, a first for the industry, which not only protects the varistor discs but also makes unit installation easier.
Every 8000 Series unit comes with a high energy test certificate, which serves as documentation that the varistors function as required. This is another distinctive feature.
De-Excitation varistors shield electricity-generating machinery (such as in nuclear and hydroelectric installations) from the harm caused by strong high energy surges.
Today, the industry pioneer in silicon carbide non-linear resistors (also known as varistors).Another unique feature is the inclusion of a high energy test certificate with every 8000 Series unit, providing proof that the varistors perform as required.
De-Excitation varistors protect electricity generating equipment (for example in hydropower and nuclear installations) from the damaging effects of powerful high energy surges.
Voltage and current characteristics of non-linear resistors, also known as varistors, which are employed as surge protectors in electronics, are not linear. The significant increase in demand for electronics circuits utilised in devices across numerous industries is responsible for the non-linear resistor market’s spectacular growth. These goods’ benefits, such as their small size, increased stability, and efficient heat dissipation, are what are causing the market to expand.
An abundant demand for non-linear resistors is also being generated by a fast increase in the sales of consumer electronics devices. Major producers are also using Silicon Carbide into non-linear resistors since it has enough advantageous properties for high energy applications like generator excitation systems and current transformers. One such manufacturer is Metrosil.
The development and use of zinc oxide nonlinear resistors for tank-type surge arresters improved their protective properties and increased their discharge performance while doubling the standard reference voltage gradient.
A simulation of the relationship between the composition of the raw material acid and the current-voltage (I-V) characteristics was conducted on the basis of high-performance elements, which offer good protective characteristics.
As a result, a higher reference voltage gradient and improved I-V nonlinearity were achieved. Additionally, by minimising their pores and enhancing the heat distribution within the element when a current is applied, the discharging capability was increased. As a result, surge arresters could use half as many elements with the same diameter.
With the expansion of the electronic circuits market in recent years, the non-linear resistors market has seen enormous growth globally. Consumer electronics items are the primary use of electronic circuits, which is fueling industry expansion.
Non-Linear resistors offer a number of advantages, including small size, stability, good tolerance, and an efficient way to reduce heat dissipation. The market for non-linear resistors is expanding due to the rising need for electronic circuits across a number of industries, including consumer electronics, automotive, and others.
Non Linear Resistance are particularly useful for tiny shunt currents in situations where wire-wound resistors typically perform less satisfactorily due to mechanical reasons, both in terms of space and reliability considerations. The comparatively large volume of resistor material that is needed may be challenging to accommodate when there are high currents involved.
Non Linear Resistance are particularly well suited to voltage division and overvoltage suppression applications where relatively tiny currents of the order of 1-10 A at typical crest voltage are sufficient.
They are not appropriate for modifying the voltage peak and RRRV. The nonlinear resistor ensures precise voltage distribution throughout the breaks and prevents overvoltages when switching small inductive currents by rapidly increasing shunt current as voltage rises.
