Our current transformers for retrofitting, which are based on the PACT RCP Rogowski coil, acquire alternating currents up to 4,000 A and convert them into an AC secondary current or into an AC mV signal, depending on the type of downstream measuring transducer. The PACT SPC split-core current transformers are suitable for smaller currents up to 100 A. The option of directly connecting the Rogowski coils or current transformers to our EMpro energy measuring devices is especially practical.

Capture alternating currents up to 4,000 A using a single compact coil type. The frequency spectrum ranges from 40 to 20,000 Hz. You can therefore also measure harmonics and transients with phase accuracy. Neither magnetic saturation nor dangerous open-circuit voltages occur.
For permanent outdoor use, the Rogowski coil of the UV version is equipped with a UV-resistant housing and UV-protected cables.
The downstream measuring transducer supplies the typical secondary current of 0 to 1 A AC, just like a standard current transformer. Select between eight current measuring ranges via DIP switch. For optimum measuring accuracy, simply use a potentiometer to compensate for the different coil lengths.
Certain product types of our EMpro energy measuring devices can be connected directly to Rogowski coils from any manufacturer. The mV signal is processed in the device. You do not need an external measuring transducer. By selecting a Rogowski coil from Phoenix Contact, you benefit from a very high level of measurement accuracy and particularly easy configuration at the same time. When the coil is connected, the respective phase can inverted by the firmware as needed. It is no longer necessary to rewire the two conductors.
