closely monitor and control the power imbalance‚ this system gives the constant supply of voltage to the load for the distribution system to show this we design the circuit where we show that how we make the constant voltage by changing the voltage using tap changer‚ we use instruments for making the constant voltage is micro controller. The equipment used for this project are two transformers‚ one for power supply and another for tap changing

Visitor counting is simply a measurement of the visitor traffic entering and exiting offices‚ malls‚ sports venues‚ etc. Counting the visitors helps to maximize the efficiency and effectiveness of employees‚ floor area and sales potential of an organization .Visitor counting is not limited to the entry/exit point of a company but has a wide range of applications that provide information to management on the volume and flow of people throughout a location. A primary method for counting the visitors

drops due to leakage. The fluid leakage cannot be detected easily unless there is a severe pressure drop in the brake pedal. This circuit senses the chance of a brake failure by across the brake switch. Its non-inverting input (pin 3) gets half the supply voltage through potential divider resistors R3 and R4 of 10 kilo-ohms each. The inverting input (pin 2) of IC2 is connected to the brake switch through diode D1‚ IC 7812 (IC1) and resistor R2. It receives a higher voltage when the brake is applied

possibility of some simple audio modulation of the arc. So‚ let’s begin! The quasi-resonant topology But to say the least‚ the first driver I have built with this topology had an AC flyback and an input power supply rated just 60 watts. The result was a compact‚ short-circuit proof‚ high voltage “lab” supply with frequency control‚ some active cooling‚ audio modulation (singing arc‚ or a plasma speaker)‚ two 5-15 kV high voltage outputs (AC and DC) to play with things such as plasma globes‚ small Jacob
