2. Surge protector - Wikipedia

   en.wikipedia.org/wiki/Surge_protector

   The terms surge protection device (SPD) and transient voltage surge suppressor (TVSS) are used to describe electrical devices typically installed in power distribution panels, process control systems, communications systems, and other heavy-duty industrial systems, for the purpose of protecting against electrical surges and spikes, including those caused by lightning.

3. IEC 61000-4-5 - Wikipedia

   en.wikipedia.org/wiki/IEC_61000-4-5

   [2] [5] The "8/20 μs" generator is designed for surge arrester testing, and produces a high-current surge into a low-impedance load. [2] On the other hand, modern electronic devices can be high and low-impedance loads simultaneously due to non-linear devices, protection circuits, and arcing in a dielectric breakdown.

4. Varistor - Wikipedia

   en.wikipedia.org/wiki/Varistor

   Metal-oxide varistor manufactured by Siemens & Halske AG. Modern varistor schematic symbol, which is the same as a thermistor symbol [1]. A varistor (a.k.a. voltage-dependent resistor (VDR)) is a surge protecting electronic component with an electrical resistance that varies with the applied voltage. [2]

5. Earthing system - Wikipedia

   en.wikipedia.org/wiki/Earthing_system

   In the event of a surge, a lightning arrester, a surge arrester or a surge protection device (SPD) will divert the excess current to the Earth before it reaches an appliance. [ 4 ] System earthing allows for equipotential bonding to all metal works to prevent potential differences between them.

6. Surge control - Wikipedia

   en.wikipedia.org/wiki/Surge_control

   Surge control products have been used in many industries to protect the maximum working pressure of hydraulic system for decades. Typical applications for surge relief equipment is in pipelines at pump stations, receiving manifolds at storage facilities, back pressure control, marine loading/off loading, site specific applications where pressure surges are generated by the automation system ...
