    Rogowski and Current Measurement

    World leaders in the design and manufacture of wide-bandwidth current measuring devices based on Rogowski Technology.

    PEM has sold its high performance ac current transducers to over 35 countries and can count major international companies, government bodies and research institutions as its customers.

    Before PEM's existence, Rogowski transducers were relatively unknown and only used for a few specialist applications. PEM can justly claim to have pioneered the general purpose Rogowski transducer as a readily available wideband commercial product. Since its first range in 1991 PEM has continued to provide state-of-the-art Rogowski transducers across a broad range of applications and provides advice and assistance to engineers with current measurement problems.

    PEM remain committed to research into the performance of Rogowski current transducers as well as other novel measurement techniques for electric current, voltage and power.

    Why Choose a Rogowski Current Transducer from PEM?

    PEM have numerous publications and patents relating to Rogowski technology. This in-depth knowledge enables PEM to provide a high level of technical support for our standard products and to offer our expertise in design and manufacture for custom applications.

    PEM’s Rogowski current transducers have many benefits:

     

    Simple to retro-fit, the clip-around Rogowski coil sensor is thin, lightweight, flexible and robust

    tick

    Coil size is not dependant on the magnitude of the current to be measured:

    • Coils small enough to fit between the legs of a TO-220 semi-conductor;
    • 20m coils to fit round a wind-turbine.
    tick

    Non-Intrusive (presents the equivalent of only a few pH to the circuit under test)

    tick

    Wide-bandwidth devices with predictable frequency response, ideal for power quality measurement or monitoring complex waveforms.

    tick

    Intrinsically safe - No danger of an open circuit secondary.

    tick

    Galvanic isolation

    tick

    Excellent linearity (Rogowski coils have no magnetic materials to saturate)

    tick

    Capable of taking huge overload currents without damage

    tick

    Immune to DC Currents - as a result it can measure small AC currents in the presence of a large DC component

     

     

    ng>產品特點ng>

    CWT LF 系列電流探頭主要為您解決低頻電流測量問題的轉換工具,它具有:

    • 測量50/60Hz微小電流
    • 測量正弦波中非常微小的相移
    • CWT的標準和微型感應套環測量電流長脈沖衰減微小

    CWT LF系列有標準長度和迷你長度的感應線圈

    ng>主要特點ng>:

    • 測量范圍:1A~300,000A;
    • 典型帶寬:0.1Hz~6MHz;
    • 纖細、柔軟的高性能感應套環:(可以定做成任意長度:標準或微型線圈)
    • 近乎為零的乾擾:在測量過程中,實際負載電流僅為幾個皮亨;
    • 輕而易舉地與實際的測量對象相連接;
    • 非常微小的‘衰減’數值;
    • CE 特征標記;
    • 瞬時電壓的輸出為峰—峰值±6V,可以直接與示波器、數據采集設備、數字電壓表以及電力記錄設備相連接,也可以作為觸發輸入。
