High Voltage Insulation / Continuity / Earth NEW MI 3290 Earth Analyser is a portable, battery or mains powered test instrument with excellent IP protection (IP 54 open case), intended for measurement of earth resistance, specific earth resistance and earth potential of various energetic and non-energetic objects. The user can choose between different methods from classic 3 wire earth resistance measurement up to one or four clamp method for measurement of pylons. He has a choice of measurement methods with different frequency methods: single frequency or frequency sweep from 55 Hz to 15 kHz, HF method with 25 kHz and pulse method simulating the lightning strike. High electrical noise immunity makes this instrument best suited for industrial environment. Instrument is available in multiple sets which are a combination of different accessories and measurement functions. MEASURING FUNCTIONS • Earth Resistance 2,3,4 -pole; • Selective Earth Resist (1 x clamp); • Earth Resistance (2 x iron clamps); • Specific Earth Resistance (Wenner and Schlumberger method); • HF-Earth Resistance (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 |js. 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). • Earth measurements on pylons with protective earth cable connected. • Measurement on mono towers and 4-leg tower. • A wide variety of measuring clamps: from iron clamps to flex clamps with 10 m length. • HF-Earth resistance measurement (acc. to IEEE_Std 81). • Sweep mode Z(f) on screen. • 3.4'' colour LCD display with touch screen. • Floating Mains (universal 90 ... 260 V AC) or battery powered (built in fast charger). • High degree of protection: IP 65 case closed, IP 54 case open. • Checkbox - different self-check methods. • DC resistance measurements. • Impulse impendance measurement for simulating the lightning strike. • Support for single or automated measurements. • PC SW for measurement pre and post processing: preparation of the test structure, result download, tree-view, table view and graphical view, storing and printing. APPLICATION Measurement of protective earthing of: • Mono and multi-leg pylons with protective earth cable connected • MV to LV transformer stations; • Ski lifts, radio towers; • Solar Power plants, wind and water turbine; • Industrial areas. STANDARDS Functionality • EN 61557 - 5 • IEEE 80 - 2000 • IEEE 81 - 2012 • IEEE 142 • IEEE 367 - 2012 Electromagnetic compatibility • EN 61326 Safety • EN 61010 - 1 • EN 61010 - 2 - 030 c • EN 61010 - 2 - 032 • EN 61010 - 031
