Market Leaders

Power Electronic Measurements Ltd (PEM) are established market leaders in the design and manufacture of wide-bandwidth current measuring devices based on Rogowski technology.

Founded in 1991 PEM can justly claim to have pioneered the general purpose wide-band Rogowski Probe. Previously this technology was relatively unknown and only used for a few specialist applications.

State-of-the-art Rogowski Probes

PEM continues to provide state-of-the-art Rogowski probes across a broad range of applications and industries and provides advice and support to engineers with current measurement challenges. To date, PEM has exported to 88 countries worldwide and can count many of the world’s leading engineering companies and research institutions as its customers.

PEM offer a number of standard product ranges which meet a wide variety of customers’ requirements. In addition we have provided custom solutions, from one off designs to volume OEM products.

Our engineers have decades of experience designing probes and sensors with Rogowski technology and are always happy to review customer requirements, be they measuring mA leakage currents, to MA lighting strikes. This in-depth knowledge and our unique and scalable in-house coil manufacturing and calibration processes have enabled PEM to solve customer’s current measurement problems for over 30 years.

Research and Development

We remain committed to research into the performance of Rogowski current probes as well as other novel measurement techniques for electrical current, voltage and power. This commitment to research and development has resulted in numerous journal publications, patents and development contracts.
