Electrical Noise Reduction in Industrial Control Systems

Equipment malfunctions caused by electrical noise transients have costly consequences. This unacceptable economic drain dictates that effective programs and practices be established to eliminate the adverse effects of noise. The responsibility for noise control falls to three principal participants in the installation: the equipment builder, the installer, and the user. Each must assume his share of the responsibility. Of these three, the equipment builder has the decisive initiative. The degree of noise immunity enjoyed by the installation will largely be determined by his packaging, wiring, and installation recommendations.
