I-Prober 520 Non Clamp Current Probe
Powertek I-Prober 520 Non-Clamp Current Probe
Isolated and Non-Intrusive High-Frequency Current Probe
The Powertek I-Prober 520 is a revolutionary non-contact and non-clamp current probe designed for fast, easy measurement of AC and DC currents in PCB tracks, component leads, and cables. Unlike traditional probes that require the conductor to pass through a magnetic loop, the I-Prober 520 works by placing the insulated tip directly onto a PCB track, allowing precise current measurement without cutting or interrupting circuits. It’s ideal for use in high-density PCBs and confined spaces.
CMC Rogowski Current Probe
Powertek CMC Rogowski Current Probe for Bearing Spark Erosion Currents
High-Frequency Common Mode Current Probe for VSDs and Bearing Spark Erosion Detection
The CMC Rogowski Current Probe from Powertek is designed to measure high-frequency common mode currents in variable speed drives (VSDs), specifically targeting bearing spark erosion currents. These currents result from high-frequency voltages induced on the machine shaft due to capacitive coupling in VSD systems, which can lead to damaging discharges through motor bearings. Over time, these currents cause bearing erosion, resulting in premature motor failure, costly maintenance, and unplanned downtime.
The CMC probe is a flexible, clip-around current sensor that builds on Powertek’s successful CWT Rogowski sensor range. It enables engineers to detect and measure the presence of bearing spark erosion currents, giving them a reference point to evaluate mitigation measures.
