For over 30 years PEM’s CWT Rogowski current probes have provided engineers a convenient, wide-bandwidth, accurate and low insertion impedance method of measuring alternating currents. 

  High-bandwidth and electrostatic shielding are characteristics of the CWTHF current probe, introduced by Power Electronic Measurements (PEM UK).

The CWTMini50HF current probe from Power Electronic Measurements (PEM UK) targets high-speed and high power-density power electronic applications. This higher bandwidth probe is ideal for measuring the faster current transients in today’s new semiconductor technologies where faster turn on and turn off times, higher blocking voltages and smaller circuits demand, smaller, higher temperature, faster current probes.

  High frequency ranges bring speed and noise immunity improvements to the established CWT range of wideband Rogowski current probes, says Chris Hewson, Power Electronic Measurements 

The PCIM exhibition in Nuremberg (May 19-20) provides a platform for Power Electronic Measurements to demonstrate its full range of Rogowski technology based wide-bandwidth current probes. Featuring the latest CWT MiniHF, the company will show how this AC probe provides better common mode immunity to local high voltage transients, and provides a more precise measurement delay which can be compensated for to give improved power loss measurement in...
