Rogowski Coil Integrators
-
Rogowski coil integrators are devices that integrate and convert the Rogowski coil output signal (a low-voltage AC signal) into a standard, easy-to-use measurement signal suitable for meters, PLCs, automation modules, data loggers, or other control devices. They are most commonly used when precise measurement of high AC currents is required and the result must be transmitted to a control system.

Types (most common variants)
By mountingDIN rail mounted (for control panel solutions)
Panel-mounted / enclosure modules (for device integration)
By output signal
Analog: 0–10 V, 0–5 V, 4–20 mA (depending on model)
“Meter-type”: 0–333 mV (for compatibility with energy meters or smart meter inputs)
By application
Single-phase or three-phase measurements (using multiple coils / channels)
Economy-class and higher-accuracy / wider bandwidth integrators
Main functions
Integration of the Rogowski coil signal into a stable measurement signal
Signal normalization to standard inputs (PLC, analyzers, meters)
Convenient installation in control panels (especially DIN versions)
Compatibility with automation equipment (BMS, SCADA, PLC, I/O modules)
Stable operation over a wide measurement range (model dependent)
Use by user groups
Home user (household):
Relevant if you have a solar power system or higher service entrance loads, want to monitor consumption in real time, or are implementing smart energy metering solutions.
Benefit: clearer energy control and consumption optimization.Electrician:
Fast installation in panels, clear wiring. Convenient for projects requiring a measurement signal for PLCs or analyzers. Ideal when a traditional current transformer cannot be installed due to space or construction constraints.
Benefit: faster project implementation, fewer mechanical limitations.Engineer / designer / automation specialist:
Easy integration into SCADA/BMS/PLC systems. Ability to select the required output signal (0–10 V / 4–20 mA / 333 mV). Convenient for reliable monitoring and load analysis.
Benefit: flexible, technically clean solution for complex systems.Advantages
Safe and convenient installation: the flexible coil can often be installed without complex work (especially where traditional current transformers cannot be used)
Suitable for high currents: hundreds to thousands of amperes
Lower system load: low-voltage signal, easy to transmit to automation systems
Versatility: easy adaptation to various controllers and metering devices by selecting the appropriate output
Pros
Fast and neat solution in electrical panels (DIN)
Easier integration with PLC and monitoring systems
Convenient for retrofitting existing installations
Wide range of applications: energy monitoring, load control, metering, process automation
Cons
External power supply required (integrator typically powered by 12/24 V DC)
Proper matching of coil parameters and integrator input/output is required for accurate measurements
Rogowski solutions are typically intended for AC current (not suitable for DC unless specifically designed)
Incorrect output selection (e.g. 0–10 V instead of 0–333 mV) may cause incompatibility with meters
Rogowski coil integrators are a practical category for those who want accurate and convenient AC current measurement with a standard signal for automation or metering. These devices are especially valuable in modernization projects, industrial applications, and energy monitoring solutions, where fast installation, PLC compatibility, and selectable output signals are essential.
