J&D designs and manufactures the AC or DC energy meter and harmonics,Revenue grade current transformers and distributes the Partners Power Quality Meters and power meters.
Most power quality and Energy Meters use current, voltage output CTs.
J&D CTs are suitable for use in harmonics or Revenue Grade metering or in up to 20 kHz services up to 1000 Vac.
To select a meter, we recommend first deciding on a style, either a split-core (opening ),flexible Rogowski coil (opening ) or a solid-core (non-opening) CT, then select the model you need based on the maximum load current you are measuring and the size of the conductor being measured.
