Multilevel inverter
$131.02$108.18The main concept of this inverter is to use diodes and provides the multiple voltage levels through the different phases to the capacitor banks which are in series. A diode transfers a limited amount of voltage, thereby reducing the stress on other electrical devices

RFID BASED ADVANCED SMART AND SECURE RATION SYSTEM
$156.26$139.43The purpose of this Smart ration distribution system is to avoid the wastage of huge amount of money as in conventional ration distribution system. RFID tag used as an e-ration card instead of conventional ration card. Theft of ration prevented. Only authorized person has access to ration.

SMOOTH OR SOFT START OF SINGLE PHASE INDUCTION MOTOR
$65.51$53.49The main intention of this project is to provide protection for a single-phase pump motor by applying initial voltage gradually from low to high for obtaining soft start. The pump motor draws more current than its rated capacity during their starting condition which may lead to the damage of the windings of the motor. In order to avoid this problem, applied voltage is gradually increased from low to high so that the soft start of the pump motor is performed.

SOFT START OF INDUCTION MOTOR USING ACPWM
$100.97$69.72This project attempts a soft start control technique for the single-phase a.c. induction motor. The circuit operation is controlled by an 8051 family microcontroller. The drive uses a PWM controlled MOSFET and the load in series with a bridge rectifier. The device attempted here takes advantage of both the low price of the phase angle control and the low harmonic content and high efficiency that we can get with standard converter topology.

SPEED CONTROL OF INDUCTION MOTOR USING ACPWM
$100.97$88.95This project attempts a new speed control technique for the single-phase a.c. induction motor. It presents a design of a low-cost; high-efficiency drive capable of supplying a single-phase a.c. induction motor with a PWM modulated sinusoidal voltage. The circuit operation is controlled by an 8051 family microcontroller.

STREET LIGHT THAT GLOWS ON DETECTING VEHICLE MOVEMENT
$90.15$60.10This project is designed to detect a vehicle movement on road to switch on only a block of street lights that are ahead of the vehicle, and to switch off the glowing lights when the vehicle passes away from the lights. This will help to save electrical energy.

SUPER FAST ELECTRONIC CIRCUIT BREAKER
$90.15$60.10The project is designed to shut down a power supply when it is overloaded by using a super-fast electronic circuit breaker. The concept of electronic circuit breaker came into focus realizing that the conventional circuit breakers such as MCBs take longer time to trip. Therefore, for sensitive loads, it is very important to activate a tripping mechanism at the shortest possible time, preferably instantaneously.

Three Phase Transmission Line Fault Detection Over IOT Using ESP32
$152.65$140.63If we look at the present Transmission line fault detection system, there are several problems, few of which include lack of skilled labour, increased risks and also time consuming process. Automating a process is known to solve many or all of such problems faced in the conventional processes. This is one such attempt to create an easy and cost-effective solution which is applicable in the upcoming power transmission systems for Electricity providers and operators at various stages or stations.

Transformer Health Monitoring
$88.35$76.33Transformers are a vital part of the transmission and distribution system. Monitoring transformers for problems before they occur can prevent faults that are costly to repair and result in a loss of service. The performance of prototype model developed is tested at laboratory for monitoring various parameters like transformer Over voltage and Under Voltage, Over current and Under current, Over temperature etc.

Transformer Health Monitoring over IOT using Arduino
$120.20$96.16A recent huge interest in Machine to Machine communication is known as the Internet of Things (IoT), to allow the possibility for autonomous devices to use Internet for exchanging the data. This work presents design and execution of real time monitoring and fault detection of transformer and record key operation indicators of a dispersion transformer like load ,fire, gas, transformer temperature and humidity. They have to look at it continuously. By using this project it can minimize working efforts and improve accuracy, stability, efficiency.

UNDERGROUND LINE TO GROUND AND OPEN CABLE FAULT DETECTION
$108.18$74.52To determine the LINE TO GROUND AND OPEN LINE FAULT DISTANCE LOCATOR IN UNDERGROUND OR OVERLINE CABLE FAULT from base station in kilometers USING AN Arduino board. 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 proposed system is to find the exact location of the fault.
