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. Uninterruptible power supply - Wikipedia

   en.wikipedia.org/wiki/Uninterruptible_power_supply

   Almost all UPSs also contain integrated surge protection to shield the output appliances from voltage spikes. A UPS is typically used to protect hardware such as computers , hospital equipment, data centers , telecommunications equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious ...

5. Power strip - Wikipedia

   en.wikipedia.org/wiki/Power_strip

   A North American power strip with two USB power ports that includes a built in surge protector. A power strip (also known as a multi-socket, power board and many other variations [a]) is a block of electrical sockets that attaches to the end of a flexible cable (typically with a mains plug on the other end), allowing multiple electrical devices to be powered from a single electrical socket.

6. 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 ...

7. Inrush current limiter - Wikipedia

   en.wikipedia.org/wiki/Inrush_current_limiter

   The most popular application is the inrush protection of the AC current in switching power supplies (SPS). The primary reason for having surge current suppression in a SPS is to protect the diode bridge rectifier as the input or charging capacitor is initially charged. This capacitor draws significant current during the first half AC cycle and ...
