110KV SUB-STATION PARUTHIPARA INTRODUCTION The hydel power development in Kerala began with the commissioning of Pallivasal hydro electric project in 1940. Next few decades saw the progressive developments of various schemes. The Paruthipara substation is the oldest substation in Trivandrum. There are 4 main feeders into this substation .it consists of a upper yard and a lower yard. The upper yard has the 2 feeders from Pothencode substation. These are 110kv feeders. The power basically

Abstract This report contains an account of my final year project‚ which was carried out in the two and half year of the Electronic and Electrical of Engineering (EEE) diploma at Institut Teknologi dan Pengurusan Lebuh Victoria. This paper is based on the design and analysis of Heat Sensor with water pump system using cooling fan to reduce the temperature. This project was done to see the operation of heat sensor and how the water pump system and the cooling fan work. This project is divided into

IC 7805- The input voltage must always be higher than the output voltage by some minimum amount (typically 1.5 to 2 volts) . 7805 is a linear voltage regulator‚ so it is not very efficient and it has drop out voltage problem. As they are based on a linear regulator design‚ the input current required is always the same as the output current. As the input voltage must always be higher than the output voltage‚ this means that the total power (voltage multiplied by current) going into the 78xx will be

INTRODUCTION The primary function of protective devices in a power system is to detect short circuits and isolate the fault by activating the appropriate circuit interrupting devices‚ which increases the reliability and safety of the electrical system. The relay co-ordination study is required to select the protective devices and necessary settings so that circuit interrupter closest to the fault opens before other devices. SCOPE OF WORK Perform protective device co-ordination analysis for HV panels

circuit is omitted for simplicity. In reality‚ the circuit looks something like this: Typically in industrial relay logic circuits‚ but not always‚ the operating voltage for the switch contacts and relay coils will be 120 volts AC. Lower voltage AC and even DC systems are sometimes built and documented according to "ladder" diagrams: So long as the switch contacts and relay coils are all adequately rated‚ it really doesn’t matter what level of voltage is chosen for the system to operate
