The makers and end-customers of these contraptions or systems are depending on additional state-of-the-art headways that are electrically ensured, distortion free and pass on higher accuracy that grants action in under impeccable conditions. Perhaps the best region is the electronic devices, the science that incorporates the assessment and utilization of incredibly small scale systems and can be used over the entire science field. This assessment investigated the amplitudes of telluric currents in Embakasi, Nairobi City and Ongata Rongai, Kajiado counties, considering a locale of 10000 m2 as a result of obliged space available in each zone. Measurements were done by use of EX542:12 Multimeter and analysis conducted using informative sensible software known as Statistica. The measurements gave extents of constraining level of electrical hazard exhibited by telluric currents to electrical, electronic and media transmission devices or systems that rely upon these devices. The amplitudes of telluric currents measured and analyzed were seen as significant to present perilous electrical condition to underground structures, in this way measures to alleviate the risks were prescribed, such as electromagnetic shielding and earthing. To improve on the amplitudes of the measured telluric currents, the electrodes should be of high electrical properties such as silver coated electrodes. The choice of area of study was advised by higher concentration of underground installations in Nairobi county in relation to Kajiado county, hence basis of telluric currents measurement comparison.enAnalysisTelluric CurrentsMiniature ElectricalElectronic CircuitsNairobi CityKajiado CountyKenyaThesis
