About Rogowski Coils

What is a Rogowski coil?

Rogowski coils are a flexible current

transducers that have been used for

the detection and measurement of

electric currents for decades. They

are based on a simple principle: an

“air-cored” coil is placed around the

conductor in a toroidal fashion and

the magnetic field produced by the

current induces a voltage in the coil.

The voltage output is proportional to

the rate of change of current. This

voltage is integrated, thus producing

an output proportional to the

current.

By using precision winding

techniques, especially developed for

the purpose, the coils are

manufactured so that their output is

not influenced by the position of the

conductor within the toroid, and to

reject interference from external

magnetic fields caused, for example,

from nearby conductors.

Basically, a Rogowski coil current

measuring system consists of a

combination of a coil and

conditioning electronics. Rogowski

coil current transducers are used for

AC measurement.

The transducer does not measure

direct currents but, unlike a current

transformer, it can carry out accurate

measurements of AC component

even if there is a large superimposed

DC component, since there is no iron

core causing saturation. This feature

is particularly useful for measuring

ripple currents for example in battery

charging systems.

Rogowski coils can be used in similar

circumstances to current

transformers but for many

applications they have considerable

advantages:

•Wide dynamic range

•High linearity

•Very useful with large size or

awkward shaped conductors or

in places with limited access

•Unlike traditional current

transducers, there is no danger

from open-circuited secondaries

•They cannot be damaged by

large overloads

•Measurement uniformity at any

position of the conductor inside

the coil

•They are non-intrusive

•They are light weighted and in

some applications are light

enough to be suspended on the

conductor being measured

•Excellent degree of rejection to

the external current conductor

What does the Integrator

do?

The integrator is a built-in analog

integral circuit, which calculates true

RMS and converts the coil’s output

into a 4-20mA or Modbus standard

signal. The integrator is powered by

24VDC.

Rogowski coil output is a weak

voltage (mV) signal. The integrator

has ability to amplify and convert it to

standard signal which can be read by

power meters, your PLC or display.

Rogowski coil output is proportional

to the frequency of the measured

current. The signal equalization

ensures a linear response on a wide

frequency range. The integrator

allows you to use coils on different

electrical network frequencies,

keeping the same output level over

the frequencies.

An integrator is essential to equalize

and shift the output signal from the

Rogowski coils by 90°. It consists of

an active electronic circuit with

negligible offset and a good linearity.
