Fluke 1625 earth ground tester

The Fluke 1625 is intended for electrical utility or other high frequency environments as it has extra versatility for more demanding applications.

The Fluke 1625 is a distinctive earth ground tester that can perform all four types of earth ground measurement. Not only measure ground resistance using the classic 'fall of potential test' but also enable time saving testing using the 'selective' and 'stakeless' methods. 'Selective' testing does not require the electrode under test to be disconnected during the measurement, thus increasing safety. The simple 'stakeless' method quickly checks ground connections using two current transformers (probes) clamped around the ground conductor under test.

Testing Methods

3- and 4-Pole Fall of Potential – standard earth ground testing using two ground stakes
4-Pole Soil Resistivity testing – determine soil resistivity using four ground stakes
Selective testing – without disconnecting ground rods, a technician can measure ground resistance using a combination of stakes and a clamp.
Stakeless testing – innovative solution using only clamps, instead of ground stakes, to measure earth ground loop resistance.

The Fluke 1625 offers these advanced features:

Automatic Frequency Control (AFC) – identifies existing interference and chooses a measurement frequency to minimize its effect, providing a more accurate earth ground value.
R* measurement – calculates earth ground impedance at 55 Hz to more accurately reflect the earth ground resistance that a fault-to-earth ground would see.
Adjustable limits – for quick test result verification.

Earth ground resistance and soil resistivity should be measured when:

Designing earth ground systems
Installing new ground system and electrical equipment
Periodically testing ground and lightning protection systems
Installing large electrical equipment such as transformers, switchgears, machines, etc.
