性能概述：
pem系列柔性电流探头，电流转换器用在测量电流方面，它提供电压与电流的比例（如：1mv/a），跟踪电流随时间的变化，因此可以在示波器或者任何数据记录器上再现波形，或输出到数字电压表（dvm并得到一个电流的有效值。采用了这种技术，pem探头可以实现宽广的测量范围，频率可从0.1hz到17mhz，电流范围从ma级别到数百ka级别，大大解决了电流测试的难题。由于线圈轻巧柔软且可以拆卸，可以探测到许多硬制探头无法达到的地方，例如ups机箱内部或者直径很大的设备上。

rogowski and current measurementworld leaders in the design and manufacture ofwide-bandwidthcurrent measuring devices based on rogowskitechnology.
pem has sold its high performance ac current transducers toover35 countries and can count major internationalcompanies,government bodies and research institutions as itscustomers.
before pem's existence, rogowski transducers wererelativelyunknown and only used for a few specialist applications.pem canjustly claim to have pioneered the general purposerogowskitransducer as a readily available wideband commercialproduct.since its first range in 1991 pem has continued toprovidestate-of-the-art rogowski transducers across a broad rangeofapplications and provides advice and assistance to engineerswithcurrent measurement problems.
pem remain committed to research into the performance ofrogowskicurrent transducers as well as other novel measurementtechniquesfor electric current, voltage and power.
why choose a rogowski current transducer from pem?pem have numerous publications and patents relating torogowskitechnology. this in-depth knowledge enables pem to providea highlevel of technical support for our standard products and toofferour expertise in design and manufacture forcustomapplications.
pem’s rogowski current transducers have many benefits:
simple to retro-fit, the clip-around rogowski coil sensoristhin, lightweight, flexible and robust
coil size is not dependant on the magnitude of the current tobemeasured:
coils small enough to fit between the legs of ato-220semi-conductor;20m coils to fit round a wind-turbine.
non-intrusive (presents the equivalent of only a few ph tothecircuit under test)
wide-bandwidth devices with predictable frequency response,idealfor power quality measurement or monitoring complexwaveforms.
intrinsically safe - no danger of an open circuit secondary.
galvanic isolation
excellent linearity (rogowski coils have no magnetic materialstosaturate)
capable of taking huge overload currents without damage
immune to dc currents - as a result it can measure smallaccurrents in the presence of a large dc component
