1.INTRODUCTION
1.1
The Internet of Things (IoT) has revolutionized variousindustriesbyenablingseamlessconnectivityanddata exchange between physical devices. Inthe realm of power transmission and distribution, IoT technologies offer immensepotentialforenhancingmonitoring,management, and overall efficiency of the electrical grid. This project focusesonleveragingIoTforthewirelesscommunicationof transmission line parameters, employing Nordic Semiconductor'sNRFseriesasacornerstoneforconnectivity. Transmissionlinesformthebackboneoftheelectricalgrid, carryinghigh- voltage electricity over long distances from power generation plants to distribution substations. Monitoring the parameters of these transmission lines is criticalforensuringgridreliability,preventingoutages,and optimizing power flow. Traditionally, this monitoring has been conducted through manual inspections or wired communication systems, which are often labor-intensive, costly,andlimitedinscalability.ByintegratingNRFmodules withsensorscapableofmeasuringparameterssuchasvoltage, current, temperature, and line sag, this project aims to develop a comprehensive IoT framework for transmission linemonitoring.Thesesensors,strategicallydeployedalong thetransmissionlines,wirelesslycommunicatewithacentral monitoringstationusingNRFmodules,therebyeliminating theneedforwiredconnectionsandenablingseamlessdata

Therefore, mesh and other types of networks use this module.
The transformer, in a simple way, can be described as a device that steps up or steps down voltage. In a step-up transformer,theoutputvoltageisincreased,andinastepdowntransformer,theoutputvoltageisdecreased.Thestepup transformer will decrease the output current, and the step-downtransformerwillincreasetheoutputcurrentto keeptheinputandoutputpowerofthesystem equal.

Bypass capacitors are typically placed in parallel with the power supply lines or signal lines of integrated circuits (ICs) or other active components. They provide a low-impedance pathforhigh- frequencynoisecurrentstoflowtoground, preventing them from affecting the performance of the circuit.

A filter capacitor, also known as a smoothing capacitor or reservoir capacitor, is an electronic component used in electricalcircuitstofilterorsmoothvariationsinvoltageor current.Inalternatingcurrent(AC)circuits,filtercapacitors areoftenconnectedinparallelwithaloadorpowersupply to reduce or eliminate fluctuations in voltage caused by variations in the input power source or by switching components.Theystoreelectricalchargeduringperiodsof high voltage and release it during periods of low voltage, effectively smoothing out the waveform. In direct current
(DC)circuits,filtercapacitorsarecommonlyusedinpower supplies to remove ripple voltage or noise caused by the rectificationprocess.
