NoZap is not a surge protector (it won t protect your computer from hardware damage resulting from a power spike), but it will protect you from momentary electric dropouts and loose connections that can cost you time and effort. Once you ve run NoZap and entered a filename, it will save the current version of the program every ten minutes with an updated filename. You don t have to do anything—the operation is totally transparent. Every ten minutes, NoZap waits until you finish the line you re working on, and when you press RETURN to enter the line, it automatically saves. 

Realistically, having a surge protector is better than not having one, but not by much. It s better to use a line conditioner that can absorb the overvoltage than to use a circuit breaker. 

Another common reason to add a filler to a polymer is to increase either electrical conductivity or thermal conductivity. Polymers typically have electrical conductivity from 10 to 10 S/cm though the addition of a moderately conductive filler such as carbon black conductivities of lO -lO S/cm are possible highly conductive fillers such as silver can raise this value to 10 -10 S/cm. Applications include static dissipative devices and surge protectors. The impact of adding a highly thermally conductive filler to a polymer is much smaller at low-volume fractions vs. the impact of an electrically conductive filler on electrical conductivity. However, if a highly loaded stiff product is acceptable, polymer composites are capable of dissipating substantial amounts of heat. 

A varistor is used in an electric circuit as protection against large voltage pulses, i.e., a surge protector. Such devices are particularly important in protecting microelectronic devices. ZnO is the most widely used and important material for varistors. 

Extension devices equipped with surge protectors can be permanently used with equipment that contains microprocessors, such as computers, but surge protectors should not be used in areas subject to moisture, physical or chemical damage, or flammable vapors. 

The surge impedance, measured by a dynamic ground tester, should be 25 co or less. This upper-limit number is chosen so that less stress will be placed on the equipment and its surge protectors. With an 18-kA strike to a 25 ground system, the entire system will rise 450 kV above the rest of the world at peak current. This voltage has the potential to jump almost 15.750 in. (0.35 in./lO kV at standard atmospheric conditions of 25°C, 30 in. of mercury and 50% relative humidity). 

A useful avalanche diode that works in either direction is the "varistor," sometimes called the "metal oxide varistor," or "MOV." It is not just a single crystal device as the previously described semiconductors are, but instead it is polycrystalline ceramic material, usually zinc oxide, with many small PN junctions at the grain boundaries. It is quite inexpensive and is very rugged, so it can be found as an important part inside most "surge protector power strips" for connecting multiple computer modems, printers, etc., to protect them against inductive kicks and even most "spikes" ("transients") from lightning. ...

It is preferable to use flow restrictors or surge protectors on flammable gas cylinders so that there cannot be a sudden large flow of gas if a rupture or other unexpected release happens in the system.
