GPC80

Split-Rigid Rogowski Coil

Suitable to Measure Currents from mAmps to kAmps High Linearity Wide Dynamic Range No Danger from Open-Circuited Secondary Cannot be Damaged by Large Overloads Non-Intrusive, no Power Drawn from the Mains Light Enough to be Suspended on the ConductorBeing Measured Coil Internal Diameter from 40 to 100 mm Very Useful for Measurements in Places with LimitedAvailable Space General Description Benefits

• • Unlike traditional current transformer with magnetic core,the Rogowski coil is a non-intrusive transducer. Since it has no hard core, it draws no power from the main circuit carrying the current to be measured. The absence of magnetic core grants a wide frequencyresponse, up to hundreds of kHz. This make GPC80 particularly suitable for measurement of harmonic content and transients. GPC80 is a split-rigid current transducer based on Rogowski principle, particularly suitable for measurement in places with limited available space.GPC80 coils are available in different sizes, starting from aninternal diameter of 40 mm. They can be used in all those applications, in which traditional transducers are not professional fitting due to its size and/or weight.GPC80 coils offer a very good linearity when subjected tovery high currents because they are not affected by saturation. They are particularly suitable for current measurement in high power and/or high frequency control devices, welding center, etc.The excellent transient response make them also suitable ascurrent transducers for protection systems.The Rogowski coils must be connected to an electronicintegrator for 90° phase shift compensation and frequency equalization.Our portable and panel meters can interface Rogowski coilsdirectly without the need of the external integrators. This is an advantage because there is no external boxes or any power dispensing with consequent ease of use.The particular features of the Rogowski coils combined withthe extremely flexible input programming of our portable meters, allow to carry out measurement by all applications. • ••••• GPC80 is small and lightweight. It can be used for currentmeasurement in places with limited available space like for example junction boxes. It is lightweighted therefore it is not necessary to fix the transducer, allowing time and cost saving on mounting. The coil output gives a low voltage signal, therefore thereis no danger from open-circuited secondary. This makes Rogowski transducers also suitable for temporary measurements, for example in combination with portable analysers.
