Ground testers for quick electrical equipment verification
Fluke's 1623-2 and 1625-2 Earth Ground Testers come are designed to speed verification of a reliable connection to earth for grounded electrical systems while lowering the risk of shock to users.
Fluke's 1623-2 and 1625-2 Earth Ground Testers come with features and accessories designed to speed verification of a reliable connection to earth for grounded electrical systems, helping solve power quality problems and lowering the risk of shock to users.
The Earth Ground Testers help engineers and electricians meet electrical codes, engineering standards, and local regulations to ensure that in the event of a lightning strike or utility overvoltage current will find a safe path to earth. They perform all four types of earth ground measurements: 3- and 4-pole fall-of-potential, 4-pole soil resistivity, selective testing, and stakeless testing.
The advanced testers feature USB connectivity for easy storage of up to 1,500 records with time stamp and fast measurement download, eliminating the need for manual data transfer.
Accessories include heavy-duty stakes that can be hammered into hard ground, color-coded wires to reduce errors, and a carry case.
The 1625-2 model has additional features including automatic frequency control (AFC), which identifies existing interference and chooses a measurement frequency to provide more accurate values. It also has R* measurement, which calculates earth ground impedance with 55 Hz to more accurately reflect the resistance that a fault-to-earth ground would experience.
Optional accessories include a 320 mm (12.7 in) split core transformer for performing selective testing on individual tower legs.
