You use varistor wich has the max voltage for that aplication example:
vacuumcleaner
max allowed voltage is 240v ac so you chose aprox. 250 V varistor.
How i determine correct size varistor for protect system which work with 220 v AC?
Set 0=(denominator of the System Transfer Function), this is the Characteristic Equation of that system. This equation is used to determine the stability of a system and to determine how a controller should be designed to stabilize a system.
50 kilograms is used in the metric system to determine weight. When converted to the U.S. system of pounds, it is 110.23 pounds.

CondenSER is correct. CondenSOR is not a real word. Regards!

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.
Bones support and protect your body. Without bones, you would be a giant pile of plop. :) Bones also protect your inner organs such as your heart,( protected by ribs) or your brain (protected by skull). Skin also protects your insides as well..... if I am correct... The immune system and skin protect the body from microbes and germs.
The equation is quite simple. Multiply the number of lights on the system by their wattage to determine the system wattage.

it cant protect the system against power surges
The correct unit for speed in MKS system is 'm'.

You can troubleshoot problems with your pa system speaker by restarting the electricity source. www.homerecordingconnection.com has good information too. You will fist need to determine if you have power to the PA system. If you have power but no sound,make sure all connections are secure, and correct.
