A varistor is essentially a transient voltage suppressor or a surge protector. They are used in a number of devices that need a consistent voltage across the system for reliable operation. In the power industry, varistors are used in high voltage transmission systems to protect the grid from line surges caused by things like lightning strikes.
Varistors are variable resistors that act as a shunt, allowing the flow of current under normal voltage but restricting current flow at or above the clamping voltage-the voltage required to trigger the sintering of the varistors zinc oxide and ceramic matrix. Varistors are vital in all electrical transmission applications, but new and better varistors are needed to protect extremely high voltage systems from line surges.
Varistor technology is one of the limiting agents on the maximum voltage of high voltage transmission systems. Using zinc-oxide nanoparticles in the varistor matrix will produce varistors with better performance characteristics, ultimately increasing reliability, more efficient transmission technologies and smaller vasristors. This technology will aid in the development of super high voltage transmission networks that operate at voltages as high as 1500kV while still maintaining grid stability.

How do surge protectors work to protect electronic devices from power surges?
Surge protectors work by diverting excess voltage from power surges away from electronic devices, preventing damage to them. They contain components like metal oxide varistors that absorb the excess voltage and redirect it to the ground, keeping the devices safe.
Do surge suppressors loose ability to work over time?
Sort of. It's not the time, but the energy absorbed. Most surge supressors, such as MOV's (metal oxide varistors) can only absorb so many joules of energy. During day to day operation, they absorb many small transients that you are never aware of. Eventually, they reach their limit and decrease in effectiveness or fail to function altogether. Depending on the quality of your incoming power, this could mean mere months, or could extend to several years.
What does CNR Varistor's CNR mean?

They have become the largest MOV manufacturer in both Taiwan and China. CeNtRa Science Corp. is a leading manufacturer and exporter of power protection equipments, specializing in manufacturing metal oxide varistors.
How to make a charger from a VOLTAGE transformer?
A true voltage transformer is not designed for power applications; it will only supply so many VA to your charger. I would suggest you purchase a power transformer for this application. You'll need to rectify the AC voltage, and minimize the ripple. Rectifiers are used for the first part, capacitors, varistors, and power transistors can be used to minimize the ripple.

What voltage dependent resistors made from?
Voltage-dependent resistors, commonly known as varistors, are primarily made from ceramic materials that include zinc oxide as the main component. These materials are typically mixed with other metal oxides, such as bismuth and cobalt, to enhance their electrical properties. The resulting structure allows the varistor to exhibit a non-linear resistance that decreases with increasing voltage, making it useful for voltage clamping and surge protection in electronic circuits.
