UNDERGROUND CABLE FAULT DETECTION WITH FAULT DISTANCE INDICATOR PHASE


ABSTRACT
The underground cable system is a common practice followed in many urban areas. While a fault occurs for some reason, at that time the repairing process related to that particular cable is difficult due to not knowing the exact location of the cable fault.
The objective of this project is to determine the distance of underground cable fault from base station in kilometers. When a low DC voltage is applied at the feeder end through a series resistor (Cable lines), then current would vary depending upon the location of fault in the cable. In case there is a short circuit (Line to Ground), the voltage across series resistors changes accordingly, which is then fed to an ADC to develop precise digital data which the programmed micro controller of AVR family would display in kilometers.
The project is assembled with a set of resistors representing cable length in KM’s and fault creation is made by a set of switches at every known KM to cross check the accuracy of the same. The fault occurring at a particular distance and the respective phase is displayed on a LCD interfaced to the micro controller.
Keywords: - AVR controller, fault detection, fault location, underground cable

IoT Based Contact less Tachometer with Speed Control Using AVR Microcontroller and Hall Effect Sensor

Image
ABSTRACT Tachometer is device used to count the revolutions per minute of a rotating shaft. Generally tachometer makes direct contact with the rotating shaft. It will reduce the velocity of the shaft, giving faulty readings. Hence it is needed to measure the speed of rotating shaft without direct contact. This project describes a contact -less tachometer using AVR microcontroller ATmega328P and a hall affect sensor. This device can very accurately measure the rotational speed of a shaft without even touching it. This device is built on an ATmega328P microcontroller, an alpha-numeric LCD module and a Hall Effect sensor to detect the rotation of the shaft whose speed is being measured. In this project Hall Effect sensor acts as a digital counting device. It will detect any magnetic element passing in front of it and thus, will give an output pulse for each and every rotation of the shaft. These pulses are fed to microcontroller. Microcontroller counts the pulses coming from Ha...

Power Line Carrier Communication Using X10 Protocol

Image
ABSTRACT Most   electric   power   companies   employs   power   meter reader   to   collect   data   on   the customer’s energy consumption. Usually, this task is carried out manually, which can lead to high cost and errors, causing financial losses. This project has taken some approaches to minimize these problems. As in everywhere automation is required to reduce the work so we decided to implement to automatic meter reading using power line communication (PLC). Automatic meter reading (AMR) is the modern Power measuring device. It has advantages in safety, real time measuring and time saving as well as it has a better user interface and digital data analysis. Data is   send   over   existing   power   line   using   X10   protocol   that   reduces   the   complexity   and   cost   of system. In the latest generation of home automation systems, appl...
