2. Surge protector - Wikipedia

   en.wikipedia.org/wiki/Surge_protector

   Surge Protection Device (SPD) for installation in a low-voltage distribution board. A surge protector (or spike suppressor, surge suppressor, surge diverter, [1] surge protection device (SPD), transient voltage suppressor (TVS) or transient voltage surge suppressor (TVSS)) is an appliance or device intended to protect electrical devices in alternating current (AC) circuits from voltage spikes ...

3. Network protector - Wikipedia

   en.wikipedia.org/wiki/Network_protector

   A network protector is a type of electric protective device used in electricity distribution systems. The network protector automatically disconnect its associated distribution transformer from the secondary network when the power starts flowing in reverse direction. Network protectors are used on both spot networks and grid networks. The ...

4. 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.

   A tariff is a tax on goods brought into the U.S. The tariffs collected by Customs and Border Protection agents are directed to the U.S. Treasury. The U.S. controls which countries and goods it ...

6. Transient-voltage-suppression diode - Wikipedia

   en.wikipedia.org/wiki/Transient-voltage...

   A transient-voltage-suppression diode can respond to over-voltages faster than other common over-voltage protection components such as varistors or gas discharge tubes. The actual clamping occurs in roughly one picosecond, but in a practical circuit the inductance of the wires leading to the device imposes a higher limit. This makes transient ...

7. Lightning arrester - Wikipedia

   en.wikipedia.org/wiki/Lightning_arrester

   Powerline worker performs maintenance of a lightning arrester on an electrical transmission tower in New Brunswick, Canada. A lightning arrester (alternative spelling lightning arrestor) (also called lightning isolator) is a device, essentially an air gap between an electric wire and ground, used on electric power transmission and telecommunication systems to protect the insulation and ...
