AC DIMMER TO CONTROL AC VOLTAGE, SPEED OF INDUCTION MOTOR OR HEATER COIL
₹4,400.00₹3,400.00A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, TRIACs, SCRs or IGBTs, which converts a fixed voltage, fixed frequency alternating current (AC) electrical input supply to obtain variable voltage in output delivered to a resistive load.
Induction motor speed control is done by varying the frequency of the applied voltage. Raising or lowering the voltage can have some speed control effects but these will be small, difficult to control, load-dependent, possibly cause the motor to overheat and, are not generally recommended.

ACPWM power control using 555IC and IGBT
₹4,100.00₹3,200.00This 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 555 astable multivibrator. The device is aimed at substituting the commonly used triac phase angle control drives. The circuit is capable of supplying a single-phase a.c. induction motor (or general a.c. inductive/resistive load) with varying a.c. voltage.

AUTOMATIC IDENTIFICATION OF ELECTRICITY THEFT
₹10,000.00₹6,000.00In proposed system automatic identification of electricity theft using arduino. If we implement the project for a complete network of a area which will be consuming a very huge amount of energy. Here we are using arduino board, LCD display, current sensor, buzzer. And here in this project we can calculate the energy or power transmitted by the KEB and the energy consumed by the network of area. If both transmitted power by the KEB and the consumed power by the area differ by a large value the arduino will display these difference in the power reading on the LCD and the buzzer located in the KEB starts beeping indicating theft of electricity. As total Power losses equals transmission power losses plus distribution power losses.

Automatic Load Sharing By Parallel Transformer
₹6,200.00₹4,200.00Transformer is basically a static device which transfers the electrical power from one circuit to another circuit with desired change in voltage and current at constant frequency. It is only one device which operates at highest efficiency at full load condition. But abnormal condition occurs at overloading condition which may result in severe problem in future.

DC MOTOR SPEED CONTROL USING 555 TIMER IC
₹2,000.00₹1,600.00This project is designed to control the speed of a DC motor using PWM control using 555 IC. The speed of the DC motor is directly proportional to the voltage applied across its terminals. Hence, if the voltage across the motor terminal is varied, then the speed can also be varied.

LINE TO GROUND AND LINE TO LINE FAULT DETECTION OVER IOT
₹12,500.00₹9,400.00The objective of this project is to determine the distance of line to ground and line to line fault from base station in kilometers using an Arduino board over IOT. This 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.

SOFT START OF INDUCTION MOTOR USING ACPWM
₹5,100.00₹4,200.00This 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.

SOFT START OF SINGLE PHASE INDUCTION MOTOR
₹0.00The 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.
