What is a Surge? Surge Also known as a transient Simply put: It is a random, high energy, short duration electrical disturbance A subcycle disturbance in the AC waveform that is evidenced by a sharp, brief discontinuity of the waveform Often nano or micro-seconds in duration 4 4 What is a Surge? Surge The Following Terms: Glitch Blackout Power Surge Spike Subcycle Outage IEEE avoids the use of these terms as there is no common use for these words 5 5 What is a Surge? Surge Overvoltage Overvoltage An increase in AC voltage at the power frequency (i.e. 60 Hz) for a period of time typically greater than 1 minute Often results from utility regulation issues or open neutral on residential power systems 6 6 2
Where Do Surges Come From? 20% 80% 80% Internal Air Conditioner Furnace Garage Door Power Tools Any Motor Load Turning On & Off 20% External Lightning Power Companies Switching Loads Lightning is the first cause of surges that come to mind, but subtle internal causes are more common 7 7 Harm Caused by Surges Voltage surges or transients damage electronic equipment by delivering more voltage than the electronics can handle. The effect is very similar to applying too much water pressure to a hose. If there is too much water pressure, the hose will burst. The same thing happens when too much electrical pressure runs through a circuit board. The circuit board bursts. 8 8 Harm Caused by Surges If a surge does not initially damage the electronics, it will reduce its life span Similar to hot water over an ice cube, the first touch does not melt it but if enough hot water is poured the ice cube is completely gone. Can cause issues with electronics Like electronic rust 9 9 3
How do surge protectors work? Metal Oxide Varistors (MOVs) are contained within Eaton s surge protectors MOVs turn on when the a surge is detected The MOV clamps the voltage and immediately sends it to ground Very simple, effective operation Complete Home Surge Protector 10 10 Surge Suppressors Act As Pressure Relief Valves The ideal surge suppressor shunts harmful surge current to ground and appears as a high impedance under normal operating conditions The surge suppressor is a self sacrificing device bearing the brunt of harmful surge currents 11 11 Normal Operation - No Protection L 12 Amps 120 Volts 10 Ω G Ohms Law I=V/R I=120V/10Ω I=12 Amps 12 12 4
Surge - No Protection L 20,000 Volts 2000 Amps 10 Ω G Ohms Law I=E/R I=20kV/10Ω I=2000 Amps 13 13 Normal Operation - Protection L 50 µa 12 Amps 10 Ω Leakage current has very negligible effect on circuit 120 Volts Ohms Law G I=E/R I=120V/10Ω I=12 Amps 14 14 Surge - With Protection 20 Amps L 2000 A 10 Ω 20,000 Volts Some residual letthrough voltage - Device manageable G Load Ohms Law I=E/R I=200V/10Ω I=20 Amps 15 15 5
Two-Stage Surge Protection Two-stage surge suppression should be provided for all cables entering a home, including power, Internet, coaxial and telephone. 16 16 Why Two Stages? IEEE Emerald Book 8.6.3 Large Surge Suppression For large surge currents, (transient) diversion is best accomplished in two stages: the first diversion should be performed at the service entrance to the building. Then, any residual voltage resulting from the action (of the suppression device) can be dealt with by a second protective device at the power panel of the computer room (or other critical load).

Frequently asked Questions What do the dollar amounts shown in the warranty section stand for (i.e. $25,000; $50,000; $75,000)? These are the MAXIMUM amounts that Eaton will pay for a connected equipment warranty claim. This would either be the amount of the damage or the homeowner s insurance deductible. Is the connected equipment warranty secondary to homeowners insurance? YES- For a valid warranty claim, Eaton will pay the cost of damage or the deductible for the homeowners insurance policy.
