Multi Ratio Current Transformers
Multi-ratio current transformers are designed to enable the customer to obtain several current ratios from a single CT.
Multi-ratio current transformers are used for relaying applications.
These units have numerous window sizes and ratios available, with up to ten different ratios from one CT depending on the model selected. All units are CSA & UL approved, and manufactured to meet the requirements of IEEE C57.13. Standard secondary taps are per IEEE C57.13 6.1d. Special tap arrangements are also available.
