  • What does CT “burden” mean?

    Why do you care about burden when ordering current transformers? Many of our customers regularly request quotes for standard and custom 5A ratio type current transformers but only ask for the window size and the input current with no knowledge of the “burden”. The burden is specified as VA or resistance (or impedance). We can […]
