A wide-band AC current probe with a small coil enabling measurement in even the most difficult to reach parts of a circuit.
The CWTMini has a small clip around coil and wide bandwidth making it useful in applications as diverse as power frequency and harmonic current analysis to measuring long duration pulses. The small coil is offered in two insulation voltages 2kV peak, 3.5mm cross section diameter and 5kV peak, 4.5mm.
Key Features
- Extended low frequency performance.
- Predictable phase response from Hz to > 100kHz.
- Low droop distortion for measuring longer pulses.
- High frequency operation into MHz.
- Current ratings from 60A pk to 300kA pk.
- Standard coil length (circumference) of 100mm or 200mm.
- Thin coils 3.5mm cross section diameter for a 2kV pk insulation and 4.5mm for a 5kV pk coil.
Applications
- Power frequency 50/60Hz measurements and higher order harmonics
- Pulsed currents, and pulsed power measurements with longer duration pulses.
- Measuring small AC currents in the presence of large DC currents (e.g. monitoring capacitor ripple).
- Power converter development and diagnostics.
- Measuring currents in difficult to reach conductors such a tightly packed bus-bars.
- Power quality monitoring in variable speed drives, UPS, power systems or SMPS circuits
