EMERSON KJ4001X1-CD1 Accessory drive

Content introduction

Protection of conductors and other systems. Protection of outside distribution circuits and components from lightning strikes is described below. Because of the large physical size of incoming ac service conductors, less impedance (resistance and inductance) is presented to transient surge current flow. As a result, amplitude and waveforms of transients appearing at ac inputs are quite different from those appearing at control, status, data, signal, and in-system power-line inputs. Therefore, protection for incoming ac power service conductors is discussed separately from that for other externally exposed lines. (1) An overhead guard wire has been proven to provide an effective level of protection for overhead service conductors against direct lightning strikes.
