Typically measured in kW and kWh. Current transformers can be easily and safely installed over existing electrical power lines without disconnecting the lines or interrupting service. They are used for a variety of application including building automation, performance verification, energy management and new technology assessment.
Extech AC/DC current clamp measures from two ranges 0 to 200 amps and 0 to 2,000 amps. See attachments for additional information.
Directly measure AC Current, AC voltage and resistance and provide a digital readout of the value. The instrument is auto ranging which means that it will changes ranges automatically. Below 100 and above, it provides readings to the nearest whole digit up to 999.
Split-core current sensors "sense" AC current from 1 to 200 Amps passing through the center conductor. Split-core current transformers are ideal for installation on existing electrical wiring by snapping around the conductor. The Magnelab SCT Current Sensor series have a self-locking mechanism.

Current Transformers (CTs) measure the amount of electricity flowing in a circuit. CTs are used with a WattNode meter, which also measures voltage.
The current and voltage measurements are used by the meter to to calculate power and energy (kW and kWh).
Standard Accuracy
Accuracy: ±0.75% from 1% to 120% of rated primary current
Phase angle: ±0.50 degrees (30 minutes) from 1% to 120% of rated current
IEEE C57.13 accuracy: class 1.2 from 1% to 120% of rated current
IEC 60044-1 accuracy: class 1.0 from 1% to 120% of rated current

Like its name implies, the RoCoil mV produces a millivolt output for use with DENT’s ELITEpro and DATApro Series dataloggers. Available in standard lengths up to 72” and current ranges up to 6000A. The RoCoil mV requires 5-24V dc, which can be supplied from the Line-Powered ELITEpro or optional external power supply. See attachment for additional information.
The Fluke 323 True-RMS AC Clamp Meter, 400A AC, 600V AC/DC is designed to verify the presence of load current, AC voltage and continuity of circuits, switches, fuses and contacts. True-RMS measurements and optimized ergonomics make the 323 a perfect general troubleshooting tool for commercial and residential electricians. This small and rugged clamp meter is ideally suited for current measurements up to 400A, in tight cable compartments.
"Split-Core" Current Transformer (SCT) provides linear output voltage that is directly proportional to the input current. This current transformer is easily and safely installed over existing electrical power lines without disconnecting the lines or interrupting service. They are used for a variety of applications including building automation, performance verification, energy management and new technology assessment.Brands, Magnelab, Dent Instruments, Onset Computer Corp.

The DENT Instruments 3000A Flexible Current Transformer is composed of a flexible sensor and an electronic module. The flexible sensor permits measurements on conductors wherestandard clamp-on current transformers could not be used. Specifically, it can be installed in tight spaces, or around breaker panels, cable bundles, wide or large bus bars and irregular shapes. See attachments for additional information.
