A Revolution in Current Transformer Testing


Different test devices and methods are used in the market to verify the performance of current transformers during development, production, installation and maintenance. Current transformers are used in electrical power systems for relaying and metering purposes. Depending on the application they are used for, the current transformers are designed differently.  Conventional testing methods can be time-consuming, material-intensive and have other limitations.

OMICRON developed the CT Analyzer test device as an innovative solution to test current transformers at all life cycle stages by using the modeling concept. The concept of modeling a current transformer allows for a detailed view of the transformer's design and its physical behavior. The test device builds a model of the current transformer automatically by using nameplate data and data measured during the test.
