What are Surges and Spikes? Surges s and Spik ikes are unexpe pect cted, d, temporar rary y and uncont ntrolle led d increas reases es in current nt or voltage in an electric ical al circuit. uit. They can be present on any metallic conductor. They can damage, degrade and even destroy electrical and electronic equipment. Surges are the most common cause of equipment damage and destruction. 1-800-753-2345 Technical Support: 1-888-472-6100 DITEKCORP.com
What Causes Surges and Spikes? EXTERNAL CAUSE INTERNAL CAUSE Lightn tnin ing g – a direct hit, usually Inducti uctive e Loads – the switching catastrophic on and off of electric motors inside or outside a facility, such as Proxim imity ty Strikes es – lightning HVAC systems, refrigeration strikes several miles away equipment, pumps and CNC causing large voltage surges machines along transmission lines Mechan hanical cal Failures ures – Utilit ity Grid Switchin ching – utility components of the electrical companies switching distribution system failing transmission lines from one supply system to another Human n Error – accidental Brownouts nouts / Black ckout outs s – under induction of AC power on low voltage or voltage sag followed by voltage system circuits a surge or spike 1-800-753-2345 Technical Support: 1-888-472-6100 DITEKCORP.com
