Current Transformer Cores

Material Features:

1, High permeability, which lead to low phase and amplitude error;

2, Very high saturation flux density compared with permalloy, which bring higher

measurement current range;

3, Low core losses which lead to low amplitude; 

4, Good temperature stability.
