PEM | Power Electronic Measurement

PEM’s Rogowski current transducers have many benefits:

Simple to retro-fit, the clip-around Rogowski coil sensor is thin, lightweight, flexible and robust.
From the smallest: Coils small enough to fit between the legs of a TO-220 semi-conductor; To the largest: 20m coils to fit round a wind-turbine.
Non-Intrusive (presents the equivalent of only a few pH to the circuit under test).
Wide-bandwidth devices with predictable frequency response, ideal for power quality measurement or monitoring complex waveforms.
Intrinsically safe - No danger of an open circuit secondary.
Galvanic isolation.
Excellent linearity (Rogowski coils have no magnetic materials to saturate).
Capable of taking huge overload currents without damage.
Immune to DC Currents - as a result it can measure small AC currents in the presence of a large DC component
