High Frequency Current Transformer


Whether you are interested in observing and measuring submilliamp currents in a charged particle beam or thousands of amps resulting from a fault in a major power feeder, you will find a Pearson current monitor to suit your needs. The use of our patented distributed termination technique permits pulse-current monitoring of rise times as short as two nanoseconds. Our current sensor devices of larger inner diameter make possible high voltage current measurement without the risk of voltage breakdown. Several of our current transformer models feature double shielding for greater noise immunity and increased safety in high voltage applications. All models are sealed and are suitable for use in high voltage insulating oil or under vacuum. They can be connected to oscilloscopes, spectrum analyzers, power analyzers, digital voltmeters, analog-to-digital convertors, and a variety of other measuring instruments.
