New CWTHF

 

Power Electronic Measurements (PEM UK) Ltd will be using PCIM Europe to launch the new CWTHF current probe which offer higher frequency operation and improved E-field immunity. 

 

Clip-on Rogowski current probes provide a convenient, wide-bandwidth and accurate means of measuring alternating currents.  The CWTHF is the latest addition to the company's CWT range and these new 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.
 

Ideal for a wide variety of applications, including power electronics development work in today's demanding noisy high-speed applications, EMC and power quality measurement in motor drives and traction, pulsed power measurements and even lightning strike currents, the CWT is available in current ratings from 30A to 300kA, with coil circumferences of 300 to 1000mm as standard and longer available on request.
