Discover the Power of Rogowski Current Probes from PEM
In high-power and complex electrical environments—like power plants, steel mills, renewable energy installations, and petrochemical facilities—accurately measuring current is a constant challenge. Traditional current transformers often fall short due to limited bandwidth, large form factors, safety risks, or inability to detect high-frequency transients and asymmetric faults.
A Smarter Solution: PEM’s Rogowski Current Sensors for Versatile, Precise Current Measurement
Pantronics India, an authorized distributor of Power Electronic Measurements (PEM), offers a comprehensive line of Rogowski current probes that deliver accurate, non-intrusive, and high-bandwidth current sensing across a wide range of demanding applications. These include models like..
1. CWT Range: Flexible, Clip-Around, Wideband AC Current Probes
The CWT series offers unmatched versatility in current sensing. Built on Rogowski coil technology, these probes support peak current ratings from 30A to 300kA. They come in a variety of coil cross-sections, ranging from just 1.2mm to 8.5mm, and lengths from 55mm for compact installations to over 1000mm for custom needs. Select models like the CWTHF, CWT Mini50HF, and the latest CWTUMHF-F include patented electrostatic shielding for enhanced signal performance.
2. RCT Range: Rogowski Current Sensors for Permanent Monitoring and Control
Designed for permanent installations, PEM’s RCT range offers a lightweight and flexible alternative to conventional current transformers. Featuring an 8.5mm coil cross-section and coil lengths of 300mm, 500mm, 700mm, and 1000mm, these sensors provide wide bandwidth performance ideal for industrial monitoring.
The electronics are available in DIN rail or panel mount versions and support rated currents from 100A to 50kA. Industry-standard output options include 0–5V AC, 0–1A AC, and 4–20mA DC, making them suitable for a wide array of control and monitoring systems.
