The clamp meter is an instrument to measure the flow of current through a cable, without the need to connect it in series, as is the case with an ammeter. This is known as a current transformer. We want to design a clamp meter to measure currents up to 100 A using a 1 V-full scale voltmeter as a sensor. Consider that the core of the torus has a permeability u 200μο 1. Calculate the number of turns N so that when a current of 100 A (rms), 60HZ passes, the scale measures 1 V (rms). 2. If you don't want to use a toroid with an iron core, but a plastic one with the same dimensions as the previous one. How many turns would it take to obtain the same measurement as the previous case?
