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:
The S Type. The core is made up of silicon steel specially processed for uniform response down to a few miliamps. This material has a high saturation point which makes the CT suitable for measuring high currents.
The R Type. This is made up of ring nickel laminations capable of linear response down to a few microamps.
The C type. This has a composite core with both the high current capability and the low current response.
The N Type. This uses the new ultra-low loss state of the art nano-crystalline material for unprecedented accuracy and linearity over a wide range of currents, temperatures and frequencies which can extend to over 100 kHz.
