Why Choose the Carlo Gavazzi ROG4X1002M9003X Rogowski Current Sensor?
The Carlo Gavazzi ROG4X1002M9003X is a flexible Rogowski coil current sensor kit designed for accurate measurement of high AC currents in electrical energy monitoring and power measurement systems. Supplied as a kit of three coils, it supports current measurement from 20 to 4000 A and is specifically designed for use with compatible Carlo Gavazzi energy analysers.
As part of the Carlo Gavazzi ROG4X series, this sensor provides a practical alternative to conventional solid-core current transformers where large conductors, busbars or restricted installation spaces make traditional CTs difficult to fit. The flexible split-coil construction allows each sensor to be installed around an existing conductor without disconnecting the power cable.
The ROG4X1002M9003X features a 900 mm coil length, a rated primary current of 4000 A and an output of 100 mV/kA at 50 Hz. Its three-coil configuration is particularly suited to three-phase power monitoring applications, while its IP67 construction provides dependable protection in demanding electrical installations.
