NEMA Arresters » Understanding the Arrester Datasheet

Since the arrester will always be self-protected with the internal components, this characteristic is essentially irrelevant. This 1.2/50μs level does not and should not match the BIL of the insulators on the system. The level on the arrester datasheet will always be lower than the BIL of the system.

Surge Arresters: fundamentals of surge arresters

A surge arrester is a protective device for limiting voltage on equipment by discharging or bypassing surge current. It prevents continued flow to follow current to ground and it is capable of repeating these functions as specified per ANSI standard C62.11. An arrester does not absorb lightning or stop lightning. It diverts the lightning, limits the voltage and protects the equipment installed

Reaction Bonded Silicon Carbide (RBSC)

6/3/2001· Reaction bonded silicon carbide is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming silicon carbide. The reaction product bonds the silicon carbide particles. Any excess silicon fills the remaining pores in the body and produces a dense SiC-Si composite.
