This thesis reports on the development of a device to measure small currents for lightning arrester monitoring. The usage of lightning arresters and surge arresters have been popularized as a means of protection for equipment from the damaging effect of surge. The health of a lighting arrester is known by observing the significance of the leakage–current– value of the arrester. Since leakage–current–is generally small, the construction of the device will focus on reading very low–current–values. Upon realizing this idea, the use of operational amplifiers and Arduino UNO is optimized. Arduino UNO functionality is very useful for this project as the measure value can be displayed on a serial port. Data can be logged in, recorded, and evaluated for future improvements and also to study on the usability of the circuit itself. Several circuit design and simulator platforms such as EAGLE software, KiCad, LTspice and Proteus Design Suite have been utilized to carry the specific task. Various simulation and tabulated outcomes are discussed in order to evaluate the efficiency of the device for accurate readings and measurements.
