Dynamometric 1ph / 3ph Power & Power Factor Meters

We are eminent manufacturer, supplier and exporter of Dynamometric 1PH / 3PH Power & Power Factor Meters in Kolkata, West Bengal, India. Dynamometric 1PH / 3PH Power & Power Factor Meters are used for measurement of active, reactive & absolute power in 1 Phase & 3 Phase systems for balanced / unbalanced load conditions. Watt, Var & VA instruments incorporate current coils, connected in series with the load & pressure coils connected across the load. These instruments work on "Air cored Electro-Dynamometric" principle. Power Factor meter incorporates two pressure coils, one with non-inductive resistance in series & other with capacitance in series & are cross connected. The deflecting torque produced is proportional to the phase angle between current & voltage vectors. The pointer rests anywhere on the scale when meter is not connected in the circuit, as there is no controlling torque.
