Carborundum - Revolvy

Silicon carbide ( SiC ), also known as carborundum , is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite . Synthetic silicon carbide powder has been mass-produced since 1893 for use as an abrasive . Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in appliions

Silicon Carbide Lightning Arresters Working Principle

Silicon Carbide Arresters (SIC): The Non linear lightning arrester basically consists of set of spark gaps in series with the silicon carbide non linear resistor elements. Lightning arresters are connected between the phase conductors and ground. During normal system operating voltage conditions, the spark gaps are non conducting and isolate the high tension (HT) conductors from the ground.

Multigap systems are successfully used in coination with a series nonlinear resistor in well-known silica carbide (SiC) ar- resters [4] for the protection of substation equipment; however, because these gapped arresters cannot withstand direct lightning strokes, they are not as suitable for lightning protection of over- head lines.

Varistor - Revolvy

Modern varistor schematic syol. A varistor is an electronic component with an electrical resistance that varies with the applied voltage. Also known as a voltage-dependent resistor (VDR), it has a nonlinear , non- ohmic current–voltage characteristic that is similar to that of a diode . In contrast to a diode however, it has the same characteristic for both directions of traversing current.
