Aneka Teknik Listrik - Electrical, by ATC Automation. Friday, September 30, 2011. Exploring Current Transformer Applications (Part 1). For a variety of applications, using current transformers is an efficient way to sense current with minimum insertion loss. How can we use this transformer and knowledge to produce something useful? With this knowledge, the user can choose the burden resistor to produce their desired output voltage. The output current of 0.1A for a 1A primary on the 1:10 turns rat...Fig 1...
