Three Phase VAR Transducer
The T-VA power transducers convert ac current and voltage signals into a load independent dc signal proportional to the apparent power (VA) flowing in the input circuit. The T-VA(H) VA-hour transducers are a combined T-VA power transducer and T-INTP integrator in a common housing and give simultaneous VA and VA-hour outputs. This does not apply to 3 element 4 wire unbalanced load transducers which, because of limited space in the enclosure 100, are supplied as two seperate units with the T-INTP integrator in enclosure 55.
