Causes of Power Surges

P.O. BOX 750 BIG SPRING, TX 79721 (432) 267-1000 THE CAUSES OF POWER SURGES Mike Craddock 2011 Electrical Power Surges range from small harmless occurrences to thunderous events that can cause extensive damage. Here is a review from small to large. Small harmless surges occur in electrical power systems almost continuously. A surge is a temporary sudden increase of voltage in the electrical circ...

P.O. BOX 750 BIG SPRING, TX 79721 (432) 267-1000 DEFINITIONS MAXIMUM CURRENT RATING Maximum current is the most current an arrestor can conduct without damage. In order to be meaningful, it is also necessary to state the time for which the current is conducted. Usually maximum current is tested using an eight by twenty test wave. This means the test surge rises from zero to maximum amplitude in ei...

Surge Capacitor Information

P.O. BOX 750 BIG SPRING, TX 79721 (432) 267-1000 SURGE CAPACITOR INFORMATION A surge capacitor is a device designed to absorb surges and/or reduce the steepness of their wave front. A capacitor is able to absorb and hold a charge of electricity, returning it to the circuit at a later time. Since the surge capacitor is always connected to the power circuit, current flows at all times. When a surge ...
