Nowadays electrical current measurements can be categorized into two methods; direct and indirect measurements. The small amount of electrical current can be directly measured by means of electrical current instrument whereas the current of high voltage cannot directly be measured by means of any physical contact of an instrument on the other hand it can be indirectly be measured through voltage transformer by stepping down voltage method in which cannot be realized economically and practically. This paper presents a method of measuring high voltage current by means of Rogowski coil detecting induced electromagnetic ware compensating unwanted induced current and finally amplifying. The results are that the reduction of measurement time and cost of purchasing the instrument.
