AEMC Instruments 6474 Kit Offers

This system tests current leakage through the tower legs and tests at frequencies up to 5 kHz to profile impedance, which is important to characterize for lightning strikes. NOTE: The GroundFlex™ Adapter Model 6474 can only be used with the Ground Tester Model 6472 Kit 500'.

Features

• 4-Pole (4-Point) Fall-of-Potential measurement for very low resistance measurements with manual automatic frequency selection and automatic lead compensation
• 3-Point Fall-of-Potential measurement
• 3-Point earth coupling measurement
• Manual or automatic frequency scan from 40 to 513 Hz for test accuracy in electrically noisy environments
• Earth coupling testing
• Selectable test voltage 16 or 32 V up to 250 mA test current
• 4-Point soil resistivity measurement with automatic calculation of Rho and user selection of Wenner or Schlumberger test method
• 2- and 4-Wire DC resistance measurement (bond testing) with automatic polarity reversal
• Ground Resistance with 2 clamps (no auxiliary rods)
• Ground Resistance of Pylons with the GroundFlex® Adapter Model 6474 and GroundFlex® sensors allow the system to measure leakage current and ground resistance of tower legs without disconnecting the overhead ground conductor
• Includes DataView® software for data storage, real-time display, analysis, report generation and system configuration
• Auto-off power management
• Automatic recognition of all electrode connections and their resistance value
• Stores up to 512 complete test results in internal memory
• Optically isolated USB communication
• Rechargeable NiMH batteries from wall charger or vehicle power

Applications

• Test active towers safely without de-energizing or disconnecting any cables
