Current transformersAccessoriesCurrent transformers –the link between power currents anddigital technologyObviously currents of several hundreds to thousands of Ampere cannot be directly digitally measured.Current transformers convert almost any amount of primary current into “bite-sized” secondarycurrents. The secondary output is .../1 or .../5A.Janitza electronics ® GmbH has a wide range of various current transformers whether these are mouldedcase type current transformer, summation current transformer or cable split core type transformer.It is recommended to select the accuracy classification of the current transformer to match the accuracyclassification of the connected measuring instruments.Areas of application:Conversion of high primary currents into standardized secondary currents .../1A or .../5ATransformer classes 0.5 or 1 depending on the instrumentTransformers are available for various bus bars and cablesMoulded case type transformers for cable or bus barsCable split core type transformers for cables when the electricity path cannot be openedSummation current transformers164
