      2. WORKING

        A Transmission system is a massive interconnected network. An Interconnected network of transmission system having a AC transmission lines. Its includes with extra high voltage levels. The main advantage of this system is that having a higher voltage. This system can reduce the losses in the Grid. The electrical energy is transported and it from the generating station to the loads, overhead lines and cables. In open country and rural areas the overhead transmission lines are used for long distances. In urban areas is the overhead transmission lines are not suitable for power transmission. So, we can provide cables for underground transmission. Because, the cost of cable is more than overhead lines. Through the cable are used in special situation but the overhead lines are cannot be used.

        The majority of transmission lines are overhead lines. In this concept a over head lines having the limited discussion only. The transformers main function is that stepping up voltages from lower generation levels to higher transmission voltage levels. And, a stepping down voltages from the higher transmission voltages to lower distribution voltages levels. In this transmission system main advantage is that having higher voltages and to reduces the losses in the Grid. This transformer operates at constant power. If the current has a lower value due to the voltages is higher. Therefore, a function of the current square in will be lower due to the losses and this is a lower at a higher voltages. In PLC using a extensive support resources and low costs are given to the some of the benefits.

        These are basis for the substation automation and SCADA system. Reliability, a large installed base and also the PLCs are extremely reliable. And, this application is

        developed the harsh industrial environments. They are designed and operate correctly to over wide temperature ranges. In very high electromagnetic noise and high vibration environments. They can operate well in dusty (or) humid environments. Designers of PLC is allowed to perfect resistance to the negative effects of harsh environments due to the number of PLCS (in the millions) have been applied in various environments. The PLC of large installed base offers the advantages of reduced costs also readily available low cast spare parts and trained personnel to work on PLC. The manufactures have been more opportunities allowed by the large is installed base and to improve design it offers new products or more varied applications.

        PLC has extensive support. So it provide in the US and most of the world. PLC manufactures have the extensive of field offices, distributions and authorized control system integrators. This PLC application is offer the courses of most technical schools and college and also the technical school and college others the PLCs programming and maintenance. The PLC offer low cost solution than traditional RTUs for SCADA systems. The sub stain and distribution automation application along with other benefits due to the PLC based system. This is so much interest and no surprise in the application of PLCs in sub stain.

  5. CONCLUSION
