CWTHF Product Launch

A new addition to our wide-band CWT range of Rogowski current probes, offering higher frequency operation and improved E-field immunity.

PCIM Europe 19 - Hall 7 | 124

We are making preparations for PCIM Europe 19 to launch our new CWTHF current probe, offering high-bandwidth and novel electrostatic shielding for excellent interference immunity.

The new CWTHF is the latest addition to the CWT range and these latest wideband probes use a novel electrostatic shielded Rogowski coil to provide excellent immunity to interference from fast local dV/dt transients or large 50/60Hz voltages. The new CWTHF offers the ability to measure faster current transient rise-times, achieving a high frequency (-3dB) bandwidth of up to 30MHz for a 300mm coil and can handle a maximum current slope of over 100kA/µs. The CWTHF probes feature a robust coil of 8.5mm thickness with a 10kV peak insulation voltage.

We will also be showing our recently launched CWTMini50HF current probe for high-speed and high power-density power electronic applications.

To compliment this new product introduction, Dr Chris Hewson will be presenting an Exhibitor Seminar on 'Delay, rise-time and slew rate using high frequency optimized CWTHF Rogowski current sensors in Power Electronics', on Thursday, 9th May 2019 at 10.40am. This presentation will cover, the improvements in bandwidth of PEM’s new CWTHF ranges of Rogowski current sensors and how this has opened-up new application areas including measurements in SiC semiconductors. Understanding the limitations of high frequency bandwidth and how this relates in practice to rise-time, slew rate and delay of these new faster probes is discussed and illustrated with practical measurement examples.
