Rigid | non-flexible "Rogowski" coils | rings | current measurement solutions
-
Rigid (non-flexible) “Rogowski” coils are professional high-accuracy current measurement solutions designed for alternating current (AC) measurement where stability, reliability, and durability are required. Unlike flexible “Rogowski” coils, rigid construction models feature a fixed geometry, ensuring consistent measurement accuracy, especially in industrial and power engineering systems.
Main purpose
Rigid “Rogowski” coils are used for measuring high and very high currents (hundreds or thousands of amperes) where traditional current transformers (CT) become inconvenient or structurally limited. They are suitable for:
Electrical distribution cabinets
Busbar current measurement
Energy analyzers and smart meters
Protection, monitoring, and automation systems
Functions and technical benefitsHigh measurement accuracy due to rigid, non-changing coil shape
Wide current range – from hundreds to several thousand amperes
Low load on the measured circuit (no magnetic core saturation)
Wide frequency range – suitable for both 50/60 Hz and higher harmonics
Compatibility with energy analyzers, metering, and protection equipment
High resistance to short-term overcurrents
ApplicationFor household users: Usually relevant for advanced users or individual projects (e.g., monitoring energy in solar power plants or workshops). Safe, non-contact measurement of high currents without direct intervention in the conductor.
For electricians: Convenient installation on busbars or conductors at predefined locations. Lower risk of errors compared to flexible coils. A solution for new installations and switchboard assembly.
For engineers / designers: Accurate and stable data for energy analysis and metering. Ability to design solutions for very high currents. Suitable for integration with BMS, EMS, SCADA systems.
For industry and power engineering specialists: Suitable for substations, production lines, data centers. Reliable operation in complex electromagnetic environments.
AdvantagesVery accurate and stable current measurement
Suitable for high and very high currents
No magnetic saturation
Long-lasting, robust construction
Suitable for professional and industrial systems
DisadvantagesLess flexible installation compared to flexible “Rogowski” coils
Usually requires an integrator / measurement module
More oriented toward professional and industrial useRigid / non-flexible “Rogowski” coils are top-class current measurement solutions designed for those who value accuracy, reliability, and stability. Suitable for industrial, power engineering, commercial facilities, and advanced electrical system projects.
