接地电阻测试仪MI 3290 GX

安装 可移植的 数字

MI 3290地球分析仪是一种便携式、电池或电源动力测试仪器的保护知识产权(IP 54开放情况下),用于测量接地电阻,特定的接地电阻和地球潜在的各种能量和non-energetic对象。用户可以选择不同的方法，从经典的3线地电阻测量到一个或四个夹具法测量塔。他选择了不同频率方法的测量方法:单频或55 Hz到15 kHz的扫频、25 kHz的高频法和模拟雷击的脉冲法。抗电噪声能力强，适用于工业环境。仪器有多套，是不同配件和测量功能的组合。•接地电阻2、3、4极;•选择性接地电阻(1 x夹钳);•接地电阻(2个铁夹);•特定接地电阻(温纳和斯伦贝谢方法);•hf -地电阻(25 kHz, acc。 to IEEE_Std 81); •Earth Resistance of mono pylons with 10 m flex clamp; •Earth Resistance of multi–leg pylons with up to four flex clamps; •Current measurement (Iron, flex clamps); •Low Ohm measurement 7 mA and 200 mA; •Earth Potential; •Step and contact measurements; •Impulse Earth measurement 10/350 µs. Key features • Possibility of performing all types of earth measurements with a single instrument. • Analysis of earth impedance as a function of the frequency due to a wide measurement frequency band (55 Hz ... 15 kHz).
