Low voltage converters: In industry, current transformers are the first link in the measuring chain for the detection of electrical sizes. By measuring the secondary current, they allow precise conclusions on the flowing current in the primary circuit. Their use ranges from simple devices such as analogue displays, to highly complex devices, such as transformers, energy meters, multifunction displays and ultimately also in monitoring systems.
