  • Three-phase electrical power measurement system including three transformers and a measurement circuit to calculate the power thereof
    Patent number: 6373238
    Abstract: A measurement system includes a first transformer enclosed within a first housing and magnetically linked to a first cable where the first transformer senses changing current within the first cable and in response produces a first output voltage. A second transformer is enclosed within a second housing and magnetically linked to a second cable where the second transformer senses changing current within the second cable and in response produces a second output voltage. A third transformer is enclosed within a third housing and magnetically linked to a third cable where third transformer senses a changing current within the third cable and in response produces a third output voltage.
    Type: Grant
