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. BS 7671 - Wikipedia

   en.wikipedia.org/wiki/BS_7671

   Amendment 1 replaced Periodic inspection reports (PIRs) with Electrical Installation Condition Reports (EICRs), a section on surge protection devices (SPDs) was introduced, and some details relating to medical locations were added. [7] Amendment 2 added a new section on electric vehicle charging. [8]

5. 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 ...

6. 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]

7. Power system protection - Wikipedia

   en.wikipedia.org/wiki/Power_system_protection

   Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults [citation needed] through the disconnection of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components ...
