The shutdown of reactors across France last year came as a shock to many, and provides a warning of the effects of stress corrosion cracking, writes Jody Muelaner
Generally speaking, a harmonic is a sinusoidal wave with a frequency that is a whole number multiple of the fundamental frequency of a periodic signal. In an electrical system, a harmonic is voltage...
