How Eaton’s devices workMost surges occur in nanoseconds. Mechanicalprotective devices are not fast enough to protectequipment from damaging surges.Our surge protective devices shunt high energy surgesaway from the equipment being protected through theuse of solid-state, thermally protected metal oxidevaristor (MOV) technology.Did you know?Overcurrent devices do not provide protection from surges 2016 Eaton.

steady fl ow from the header tank through the surge pipe. This fl ow creates a measurable head loss (due to friction) along the surge pipe from the header tank to the surge tower. To create the surge, students quickly shut the surge valve downstream of the surge pipe. VDAS displays and records the pressure surge in the surge tower. Students
surge protection units provide premier surge protection for AC power at the service entrance.

The coincidence of wind surge, spring high tide and external surge leads to extreme storm surge levels along the coast (figure 4). Figure 4: The components of a storm surge. Thus a storm surge is composed of the local tides, wind surge and a possible external surge. In the project storm surges from 1901 until 2008 at tidal gauge
surge protection arrangement is required to be done at different levels. 1.3 Surge protection devices (SPDs) Surge Protection Devices can protect the electronic equipment from the potentially destructive effects of high-voltage transients.The Surge Protection Devices have following features: 1. Rapid operation, 2. Accurate voltage control and 3.
The surge arrester protects the power systems from both the direct and indirect lightning surge by diverting the charge and energy to ground. In the process of diverting, it clamps the surge on the system from the arrester onward. Since the surge arrester has resistance even in its conductive state it does not reduce the lightning surge to zero.
