low DC voltage is applied at the feeder end through a series resistor. The current would vary depending upon the length of fault of the cable in case there is a short circuit of LL or 3L or LG etc. The series resistor voltage drop changes accordingly which is then fed to an ADC to develop precise digital data which the programmed microcontroller would display the same in Kilo meters. The project is assembled with a set of resistors representing cable length in KMs and fault creation is made

Pilot trolley method for trains AIM: To design a auto pilot trolley method for trains. Base Technology: EMBEDDED Abstract: It is a very useful project. By using this we can reduce the more train accident. The trolley is communicating with the train using ISM based RF signal. 432.92 MHz frequency signal is used for communication. As we do the project we use this frequency. It will sense the object using the IR signal‚ bomb is detected using metal detector‚ track open is sensed using limit

Department needs to test large numbers of 1000-ohm resistors to an accuracy of ±5%. To save time‚ a PIC microcontroller based Resistance Tester is to be designed to do this job. In this essay‚ it provides a state diagram of the system‚ a circuit diagram which draw by Proteus and a C programming to show how it works. The basic design is to be based on a PIC16f818 which has a 10 bit Analogue to Digital Converter (ADC) that can be used to measure the resistor being tested. One way to measure resistance is

Thermistor A thermistor is a type of resistor whose resistance varies significantly with temperature‚ more so than in standard resistors. The word is a portmanteau of thermal and resistor. Thermistors are widely used as inrush current limiters‚ temperature sensors‚ self-resetting overcurrent protectors‚ and self-regulating heating elements. Thermistors differ from resistance temperature detectors (RTD) in that the material used in a thermistor is generally a ceramic or polymer‚ while RTDs

In this lab‚ we were given an LED nightlight circuit. Upon first glance we noticed all the components‚ the zener diode‚ 3 resistors‚ a capacitor‚ 4 diodes‚ a photocell‚ an LED light‚ and something we thought was a transistor. We knew the first thing to do was to identify all of the components and find out the rating for them. We had to use the microscope to determine the identifying numbers on the zener diode‚ the capacitor‚ and the‚ assumed‚ transistor. The zener diode read 1N5242B‚ the capacitor
