VPInstruments - Current Transformers

Select your current transformer for your application. Be aware, the 3 Phase Power Meter needs to be ordered separately.

Select your 3 phase power meter and select a current transformer for each phase. For delta systems you may only need two current transformers. To determine your size of current transformer, check the maximum amperage and be sure to account for the input power factor (cos(phi)), minimum input voltage and other factors. VPInstruments 3 Phase Power Meter is compatible with VPInstruments’ current transformers or any other, when they feature a 0.3333 VAC output.

• Power consumption of large consumers (i.e. gas turbines, compressors, cooling water towers, steam turbines)
• Submetering
• Cost allocation
• Condition monitoring
• Energy management
• Efficiency calculations (i.e. compressor electrical usage vs output)

• 0.3333V output
