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.

whereas Section 534 describes the selection and installation of suitable Surge Protective Devices (SPDs), where required, for effective transient overvoltage protection. Why is transient overvoltage protection so important? Transient overvoltages are short duration surges in voltage between two or more conductors (L-PE, L-N or N-PE), which

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.
