What does the initials MOV stand for?

The initials MOV stand for Metal Oxide Varistor. It is an electronic component that protects electrical circuits from voltage spikes and transient surges by clamping down on excess energy. It can be found in surge protectors and other devices designed to safeguard against power surges.

What is the use of metal oxide varistor disc in Lightning arrestor?

I think your answer is given in previous question -( correct size of varistor across 24v coil) I am just pasting the same here. . . "When the voltage exceeds the clamping voltage of the varistor, it conducts current, preventing the voltage from reaching a dangerous level. If the elevated voltage is maintained for too long a time, the varistor will heat to a point where the metals in it melt and fuse together, causing a short. This also poses the posibility of a fire risk, as the current is now conducting heavily through the varistor. This is what often happens to a varistor in a power strip when lightening strikes nearby. It renders the power strip useless. But the connected devices are usually spared. "

How do you determine correct size varistor on a 24vac coil?

is this coil a single shot solenoid or is it used as a filter i assume you want to know a good value for a varistor to stop voltage spikes from the reverse EMF which is aprox. 4X the input voltage. so i would say to use 2X-3X the input Voltage so 48 or 72 Volt MOV (Metal oxide varistor) You want the varistor to be several volts greater than the peak voltage of the signal across which it is connected. 24 volts is probably the RMS value of the coils voltage. Your varistor must be selected to be greater than the peak voltage. When the voltage exceeds the clamping voltage of the varistor, it conducts current, preventing the voltage from reaching a dangerous level. If the elevated voltage is maintained for too long a time, the varistor will heat to a point where the metals in it melt and fuse together, causing a short. This also poses the posibility of a fire risk, as the current is now conducting heavily through the varistor. This is what often happens to a varistor in a power strip when lightening strikes nearby. It renders the power strip useless. But the connected devices are usually spared.
