ARRESTER DEFINITIONS
Clamping Voltage: The clamping voltage of an arrester is the voltage that appears across its terminals during conduction of a transient current.
Standard Wave Form: The waveform of a surge current or voltage is designated by a combination of two numbers. The first number is for the time
of the wave front expressed in microseconds from zero to the peak of the wave. The second number is for the time of the wavetail also expressed in
microseconds from zero to the instant that the wavetail reaches one half of the crest or peak value, i.e., 8/20 µs waveform.
Transient Current: The transient current of an arrestor is the peak surge current which flows through the arrester when voltage clamping occurs.
OPERATION
For maximum effectiveness, the protector should be installed directly after the AC line on/off switch and fuse. This will protect the electronics from
the AC line switch arcing and the severe transients caused by a fuse clearing.
Some heat is produced when operating at full current load, and heat sinking may be required to maintain case temperature below 85°C. The case
temperature is measured at the center of the mounting surface. The unit should not be mounted to a low combusting temperature material such as
wood.
High energy transients will cause a large circulating current in the AC input line (2,500A is possible). To prevent electromagnetic coupling, the AC line
on the input side of the protector must be dressed away from other wiring, magnetic shielding may be required. In addition, the electrical service
must be connected to a low impedance earth ground.
