    Are there any spice models available for the CR3110-3000 current transformers?

    Dear Sir,

    We do not maintain spice models for CR Magnetics CTs. All relative information on our CTs is given in the spec sheets to create a model. Typically you can use an AC current source as your model, with an amplitude of input current divided by the effective turns ratio. Depending on your spice program, some allow a phase shift parameter in the AC current supply. This could imitate the phase angle error. Proper use of a measuring CT places the operation in the linear region, so this would represent a very good simulation. I have attached the catalog page of our CR3100 Series for your convenience.
