Abstract: A micro computer based power line protection, monitoring and management system that manages one or more source(s) and one or more user(s) of the power. Further disclosed are many means of rendering the surge protection operative in many different modes, and conditions, means of providing primary protection and secondary protection in a safe way such that the system integrity is maintained in that various situation/conditions of power surges, transients and crosses, further coupled with a power management system that allows safe switching between surges and manages different loads and provided by its predetermined parameters and conditions. External communication means additionally provide the means of controlling and monitoring the sources and the loads. Various control means and isolation means separate the primary from the secondary protector providing fail safe protection under varying power conditions such as power crosses, surges and transients.
