DESIGNING OF A MICRO GRID SOLAR POWERED SYSTEM FOR KATORO RICE MILLING MACHINE

PROBLEM STATEMENT Katoro Rice Milling Machine is powered by TANESCO  but it experiences under voltage. This problem is caused by heavy loads to machine(s) because of sharing distribution transformer, when one machine with heavy load draw much power it leads to under voltage to the rest machines and these causes the machines to be operated … Read more

DESIGN OF AN AUTOMATIC POWER FACTOR IMPROVEMENT SYSTEM WITH AN ADDITION OF HARMONIC FILTER FOR MTIBWA SUGAR ESTAT

PROBLEM STATEMENT The low power factor problem at Mtibwa Sugar Estate is caused by the use of inductive loads and the presence of harmonics produced by the non-linear loads in distribution power system. These harmonics significantly reduce the life of capacitor banks and cause low PF. This increases current flow, power losses increase in both … Read more

DESIGN OF AUTOMATIC CONTROLLER OF HUNTING OF A GENERATOR AT SOMANGA GAS PLANT

  INTRODUCTION  In synchronous generator, difference of the stator frequency and rotor frequency is slip. Slip is the output of generator, when the generator is under loaded or overloaded suddenly, the frequency fluctuation try to overcome the changes. If this fluctuation continues rising and falling the slip i.e. output of the generator is disturbed, consequence … Read more

555 Timer | NE555 APPLICATION INFORMATION

DESCRIPTION INFORMATION  These devices are precision timing circuits capable of producing accurate time delays or oscillation. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the astable mode of operation, the frequency and duty cycle can be controlled independently with two external … Read more

Bridge Rectifier IC Pin out

Bridge Rectifier IC Pin out A bridge rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification. AC = Alternating current (INPUT) DC+ = Positive direct current (OUTPUT) DC- = Negative direct current (OUTPUT)
