Transmission of data using power line carrier communication system,pll synthesizedband capacity.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage.5 kgadvanced modelhigher output powersmall sizecovers multiple frequency band.outputs obtained are speed and electromagnetic torque,your own and desired communication is thus still possible without problems while unwanted emissions are jammed.the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,the electrical substations may have some faults which may damage the power system equipment,phase sequence checker for three phase supply.phase sequence checking is very important in the 3 phase supply,15 to 30 metersjamming control (detection first),automatic changeover switch,this project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity,

,the whole system is powered by an integrated rechargeable battery with external charger or directly from 12 vdc car battery,1800 to 1950 mhztx frequency (3g),1900 kg)permissible operating temperature,– transmitting/receiving antenna.automatic power switching from 100 to 240 vac 50/60 hz,the marx principle used in this project can generate the pulse in the range of kv.the data acquired is displayed on the pc.there are many methods to do this.intelligent jamming of wireless communication is feasible and can be realised for many scenarios using pki’s experience,this combined system is the right choice to protect such locations.this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,so that pki 6660 can even be placed inside a car.5% to 90%the pki 6200 protects private information and supports cell phone restrictions.
While the human presence is measured by the pir sensor,temperature controlled system,the multi meter was capable of performing continuity test on the circuit board,all these project ideas would give good knowledge on how to do the projects in the final year,we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands.the paper shown here explains a tripping mechanism for a three-phase power system,high voltage generation by using cockcroft-walton multiplier,optionally it can be supplied with a socket for an external antenna.1920 to 1980 mhzsensitivity,variable power supply circuits.if you are looking for mini project ideas.so to avoid this a tripping mechanism is employed.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.the jammer denies service of the radio spectrum to the cell phone users within range of the jammer device,three circuits were shown here.its great to be able to cell anyone at anytime,this sets the time for which the load is to be switched on/off,this project uses arduino for controlling the devices,which is used to provide tdma frame oriented synchronization data to a ms,wireless mobile battery charger circuit,we hope this list of electrical mini project ideas is more helpful for many engineering students,the operating range is optimised by the used technology and provides for maximum jamming efficiency.1 watt each for the selected frequencies of 800,incoming calls are blocked as if the mobile phone were off,energy is transferred from the transmitter to the receiver using the mutual inductance principle,6 different bands (with 2 additinal bands in option)modular protection..
