Powering Innovation in Current Measurement
PEM at a glance
PEM UK Ltd has built upon Rogowski and Steinhaus' fundamental principles established in 1912 to pioneer the development of wide-band, clip-around, Rogowski coil technology. Our extensive engineering experience and vertically integrated approach—combining in-house design, prototyping, and manufacturing capabilities—has significantly advanced current measurement capabilities, enabling us to deliver both standard and custom Rogowski coil sensors that address the most challenging measurement requirements across power electronics, e-mobility, renewables, lightning protection, and power quality monitoring among many other sectors.
PEM Announcements and Updates
New from PEM - CWTUM-S
Designed to keep pace with increasingly compact and lower profile power devices, the CWTUM-S ultra-thin 1.2mm coil can slip into compact layouts in energy dense circuits. Despite a thickness of just 1.2mm it retains a 1.2kV peak insulation capability and 125oC maximum operating temperature. Its bandwidth, spanning a few Hz to 30MHz, captures low and high frequencies crucial for in-depth performance analysis, while its peak current range enables its use monitoring in low-power devices through to high power converters.
CWTMini50HF to supersede the CWTMiniHF
From January 2025, the CWTMini50HF will supersede the CWTMiniHF in our CWT range. CWTMini50HF is a significant evolution of the CWTMiniHF and delivers improved high frequency performance with a faster response time for transient measurements. The CWTMini50HF range has been expanded to include, 2kV and 5kV peak coil insulation voltages, as well as longer coil lengths. This upgrade underscores PEM's commitment to advancing technology and meeting the evolving needs of the industry.
See the Signal, Not the Noise – Visit PEM at PCIM Booth 7-108
We’re excited to be once again at PCIM Europe in May, showcasing our CWT and RCT ranges of Rogowski coil AC current sensors.
Come and see us in booth 📍 108, Hall 7. Let's talk 💬 about applications, requirements, and practical challenges that our clip-round, wideband Rogowski sensors can help you measure. We will have three live demos at our booth!!

The history of the Rogowski coil (1912 - 1950)
Read about the early history of the Rogowski coil, from its theoretical proposal in 1912 as a current measurement device to its gradual refinement by 1950. Over four decades, the coil’s design and principles were studied, yet it remained a work in progress. Despite its experimental nature, it represented a valuable step forward in electrical engineering, sparking interest for future development.
