T-W & T-V Series Power Transducers
T-W & T-V Series data sheet.
 The T-W or T-V power transducers converts ac current and voltage signals into a load independent dc signal proportional to active power (watts) or reactive power (vars).
The T-WH and T-VH watt-hour and var-hour transducers are a combined T-W or T-V power transducer and T-INTP integrator in a common housing and give simultaneous watt and watt-hour, var and var-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.
