recognized that they are significantly affected in their performances by the properties of such interfaces. Figure Figure 1.4.1 shows three representative models for interfacial states (Tanaka 2005).
The participants become familiarized with planning of HV and MV Substation Projects (switchgear). They learn about a variety of substation schemes, the function of the components involved and become informed about the most important technical trends.
the configuration of substation Intelligent Electronic Devices (IED) which describes the structure together with physical components and their relating functions.
Substation layout consists essentially in arranging a number of switchgear components in an ordered pattern governed by their function and rules of spatial separation. Spatial Separation Earth Clearance : this is the clearance between live parts and earthed structures, walls, screens and ground.
System Based Approach The system -based approach to RCM requi res practitioners to identify critical processes or units. A critical system is one where a failure of that system causes a failure of the production unit or process.

The impacts and the degree of importance of various components on the reliability of substation automation systems are presented. Two suitable measures of importance are selected. The first is the Birnbaum’s measure used to determine the bottleneck of the system reliability. The second measure uses criticality importance to diagnose failures and generating repair or inspection checklists.
Substation Automation is an integration of various protections, control and data acquisitionf unctions on an automated platterm with minimal number of units to reduce the operating costs, lessen the control panel and room space, and to eliminate redundant equipment.
