General consideration how to select the right CT:
Calculate the nominal current: IN = SNtransformer / (UN ⋅ √3)
Look up the CT in the table above with the current range that fits best to this calculation.
If the table lists two matching CTs then it is advisable to prefer the one that allows for an optimal measurement of the short-circuit current to be expected. The short-circuit current can be measured up to the listed upper value multiplied by 20. For example: For the WIC1W2AS1, the short-circuit current can be measured up to 20⋅56 A = 1120 A. The system can withstand a primary current of 20 kA for 3 seconds, and 25 kA for 1 second.

CT/Self-powered – No auxiliary supply voltage needed
Designed for harsh environment
Compact form factor
The WI Line devices are self-powered – The protection relay does not need supply voltages for Ring Main Units (RMUs).
The primary application of WI Line devices is Feeder Protection (also as backup) that does not need supply voltage.
