In 1985, an engineer at Amecon inc. had the bright idea that increasing turns in a current transformer results in a smaller CT size and smaller secondary currents. This makes the CT suitable for use in electronic circuits. Despite reservations from the management who argued that the world was not going to change the way it monitored power, the idea slowly caught on and today it is widely and universally accepted. For almost ten years Amecon was the sole manufacturer of this device, but soon after it caught on like wild fire and today the old 5 Amp heavy and bulky current transformer is a thing of the past. Today we are pleased to announce that the engineer who first initiated this product is now with us here at General Magnetics and has launched three new types of CT’s in order to take care of every application.","These electronic type current transformers or current sensors fall into 4 main categories, which depending on the core material, can serve various applications. These are:
