The ICT 200 system has been designed to perform calibration of Isolating Current Transformers with ratios 1:1, 2:1 and 3:1. Test currents are from 1 mA to 100 A (upgradable to 200 A).
In the design of the ICT Test System, the components are mounted and interconnected in a 19-inch rack for easier setup and operation. The main system components are: an 100 A current source, a signal generator, two precision ranging CTs, a current ratio bridge and a system PC.
In order to cover the wide range of testing currents, the system has two possible configurations. One setup covers the range from 2 A to 100 A. In this setup the precision ranging CTs are in circuit in order to step down the input current to the current ratio bridge. The second setup covers the range from 1 mA to 2 A. In this case the two ranging CTs are not in circuit, therefore, the test current and the output current of the UUT (ICT) are going directly to the current ratio bridge inputs.
Only one setup can be used at a time and has to be set manually by the operator by changing connections and leads on the system rear panel. The connections for testing in the rear panel are grouped accordingly in two sections: high current setup and low current setup.
