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

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

3- Differential surge tank: an orifice tank having a riser is called differential tank. 4- One- way surge tank: in a one way surge tank the liquid flows from the tank into the pipeline only when the pressure in the pipeline drops below the liquid level in the surge tank. 5- Closed surge tank: if the top of the tank is closed and there is

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.

Type 2 surge arresters are tested with a 8/20 ms current wave. Type 3 surge arresters are tested with a 1.2/50 ms and 8/20 ms combined wave.

Lightning surge, Trans. mission Tower model, Flashover, Surge Arrester, ATP/EMTP. 1 Introduction . Lightning surge is a very natural and most unpredictable phenomenon which may disrupt power system and cause equipment's failure. Lightning generally strikes on the tall structure in everywhere. Because of the structural height

A surge tank aims reduce the effect of water hammer to protect a pipeline. For a surge tank to be effective, the maximum height of a surge must be found, then the surge tank can be properly sized for the system. This example system consists of a reservoir connected to a pipe line at the upstream end. At the end of the pipe there is a valve.

1.3. Faults Not Found with a Surge Test There are faults that can only be found with a surge test such as turn to turn insulation weaknesses, but there are also faults that a surge test will not see. These are: Resistive connections internally or externally All strands (round wires) not connected at both ends with several in hand

water can no longer go down, so it has nowhere else to go but up and inland. Hurricane Ike, a at category 2 landfall in Texas, also produced catastrophic damage with a 20-ft. storm surge. In general, storm surge occurs where winds are blowing onshore. The highest surge tends to occur near the “radius of maximum winds,” or where the

Protecting outdoor LED lighting from lightning induced surges requires diverting high voltage/ current transient interference away from sensitive electronics in the lighting fixture. A variety of surge protective devices (SPDs) are used in outdoor LED lighting to suppress surge energy and minimize surge impact.
