Choosing Current Transformers

As a general rule of thumb, you should choose a CT where the average measured current is about 75% of the CT’s max range.
This not only provides best accuracy, but best resolution. Using a large CT to measure a small current provides poor resolution and accuracy.

The bottom end range, or turn down of CTs, can be a “can of worms”, and can change depending on what equipment the CTs are connected to. Contractors hook CTs up to all sorts of things.
The general spec. for the “small” split core CTs, is therefore:
5-65A for the 50A CT, & 10-130A for the 100A CT.

However the same CTs when used with a PowerScout 3037, which has high input sensitivity, can be:
1-65A for the 50A CT,   & 2-130A for the 100A CT, as depicted & stated on the PowerScout 3037 brochure.
However, the separate spec sheet for all the CTs, has just used the general spec without adjusting ranges at the bottom end to account for the extra PS 3037 sensitivity.

If you require split core CTs with good turn down & bottom end sensitivity, look at the Mini & Midi hinged split core CTs with their ferrite cores. The Mini & Midi hinged split core CTs are cheaper than the iron cored SCS 50 & 100A CTs and have a better turn down. The only reason a client might choose an iron cored SCS-050 or SCS-100 CT, is if the larger cable opening was required.

As an example: “The RoCoil CTs when used with the ElitePro SP energy logger (top of this page) have been rated safely, as 50 – 5000A, although I have always been able to read them accurately to 20A, at which point the ElitePro SP would cut the readings off.
However, greater sensitivity with the latest ElitePro XC, has resulted in a cut off point for the RoCoils of just 5A.
ie: useful range of 5-5000A, which is a turn down ratio of 1000:1, which is remarkable.
However, there is no guarantee that a measurement of 5A can be made if the RoCoil is connected to some other piece of equipment.”

TCA-5 module

Dent TCA-5 Module: You can now use the flexible Dent RoCoil current transformers with legacy equipment that requires a 0-5A current input, with the TCA-5 high accuracy converter module.

TCA-5 5-Amp Converter Module for use with DENT Instruments RoCoil

The RoCoil TCA-5 is a three-channel integrating transconductance amplifier (TCA) that converts the 131mV/1000A electrical output signal from the RoCoil current sensor to a 5 amp AC current, emulating a traditional current sensing transformer.
TCA-5 5-Amp Converter Module for use with DENT Instruments RoCoil

TCA-5 5-Amp Converter Module for use with DENT Instruments RoCoil

Flexible Current Transformers (CTs) give a clear-cut advantage over conventional split-core or clamp-on CTs, but they do not provide the 0-5A outputs required by many applications.

The new TCA-5 from Dent Instruments fulfils this 5 amp output requirement in the marketplace.

The Dent Rocoil TCA-5 delivers the flexibility and ease of installation of the RoCoil current sensors to applications using power meters with 5A current transformer input.

Those who use 5 amp current input power meters will now be able to take advantage of the easy installation, high accuracy and broad current range coverage offered by RoCoil flex probe CTs.

The RoCoil TCA-5 is factory-calibrated to work with DENT RoCoil CTs (131mV/1000A). It is a DIN rail or panel mounted device requiring an external 48 VDC power supply. The RōCoil TCA-5 has four selectable current ranges:
500, 1K, 2.5K, and 5K amps and selectable frequency for both 50 and 60 Hz systems.

Data sheet on TCA-5 (pdf file, opens in new tab)
User Manual on TCA-5 (pdf file, opens in new tab)


AC/DC 48V Power Supply  (at the right side of the picture)

The RoCoil TCA-5 requires an external 48 VDC power supply for operation.
Two versions of the power supply are available:
a 120/240VAC “low voltage” version and a 200/500VAC “high voltage” version.
The power supply is provided as part of the RoCoil TCA-5 kit or may be ordered separately.

Selectable Current Ranges and Frequency

The RoCoil TCA-5 has four selectable current ranges: 500, 1000, 2500, and 5000A.
The range is changed using a switch on the front of the device. See Current Ranges table (left) for current range information.

A separate switch on the front is used to change the frequency between 50 and 60 Hz.

Output Impedance/Burden

The wire that connects the RoCoil TCA-5 to the power meter is supplied by the user. Linearity and precision are maintained by using the correct output wire size.

The maximum allowable output impedance (or burden) of 70 m-ohm plays a critical role in the selection of output wire size and the allowable distance between the power meter and the RoCoil TCA-5.

The voltage drop allowed by the output circuitry (i.e., the voltage drop due to current flowing through the sum of the wire resistance and meter burden) is 350 mV RMS or 1.75 VA.


The RoCoil TCA-5 is intended to be wall mounted with the output terminals facing up.
Three RoCoil current sensors will typically be installed inside the service panel at the feeder or around the branch circuit of interest.
The RoCoil TCA-5 can be mounted as a panel unit using slide-out tabs on the back or mounted on a 35 mm width DIN rail (a 10″ section of DIN rail is included when ordered as a kit).


The TCA-5 module only comes in a 3 phase version. There is no single phase version.

It will only work with DENT Instruments RoCoil CTs.
It comes into it’s own with the new CT-RXX-4A-U series of RoCoils,
with accuracy of <0.6% over the range 10% to 100% of FSD.
The linearity is also <0.1% over the range of 10% to 100%.
All RoCoils are individually tested at the factory, at 10% & 100% FSD, prior to shipment, to ensure they comply.

The TCA-5 comes complete with DIN rail mounting strip, which also mounts the external power supply.
The 48Vdc power supply comes in two versions, for single phase (A-N) & three phase for (phase-phase) delta supplies.

The great feature is that it has a mechanical range switch on the front cover, which can set the 0-5A output to represent an input range of 500A, 1000A, 2500A, & 5000A, with full resolution.
There is also a switch to select 50Hz or 60Hz supply frequency.
No software or PC set up required.

This product is only for applications where a Rogowski type CT is required to provide a 0-5A output for existing installed equipment, that will only accept a 0-5A input signal, such as metering applications.
