A power surge is one form of electrical power disturbance. There are four main types of power disturbances:
Power surges are generally considered to be the most destructive of the four types of electrical power disturbances. Power surges are spikes in voltage.
They are very brief, usually lasting millionths of a second. Power surges can vary in duration and magnitude, varying from a few hundred volts to several thousand volts. No matter where you live, your home experiences power surges. In the United States, most homes use electrical power in the form of 120-volt, 60 Hz, single phase, alternating current. However, the voltage is not delivered at a constant 120-volts. With alternating current the voltage rises and falls in a predetermined rhythm. The voltage oscillates from 0 to a peak voltage of 169 volts. Most appliances and electrical devices in your home used in the United States are designed to be powered by this form of generated electricity. During a power surge, the voltage exceeds the peak voltage of 169 volts.
A spike in voltage can be harmful to appliances and electrical devices in your home. An increase in voltage above an appliance's normal operating voltage can cause an arc of electrical current within the appliance. The heat generated in the arc causes damage to the electronic circuit boards and other electrical components.
Smaller, repeated power surges may slowly damage your electronic equipment. Your computer or stereo may continue to function after small surges occur until the integrity of the electronic components finally erode and your satellite system, cordless phone, or answering machine mysteriously stops working. Repeated, small power surges shorten the life of appliances and electronics.

With the Ditek Corp. DTK-WH5 PLUS Whole Home Surge Protection System
Electrical Service Entrance (DTK-120/240HD2)
This hard-wire service entrance unit is mounted on the Main Panel, protecting all the power outlets within the home. All Service Entrance products offered are specifically designed to prevent external catastrophic, high-voltage spikes and surges from entering the home. These products consistently reduce the potentially damaging voltage spikes to "acceptable" levels.
Telephone Service Entrance (DTK-2LVLPSCPRUV)
A telephone entry device is placed at the demarc for the incoming telephone lines. Standard telephone entry will protect two (2) incoming pairs. Optional product configurations will protect up to four (4) incoming pairs. Installing the protection device at this point effectively protects all phone jacks within the home that are used for voice or modem connection.
CATV/Satellite Service Entrance (DTK-VSPA)
A cable entry device is placed as the demarc for incoming cable/satellite lines. Standard cable entry protection will protect one (1) incoming cable line. Optional product configurations will protect up to two (2) incoming cables. Installing this protection device at thsi point will effectively protect all CATV/Satellite jacks within the home, without signal loss or degradation.
