Fluke 1630-2/1630-2 FC - Earth Ground Clamp Manual

Introduction

The Fluke 1630-2/1630-2 FC Earth Ground Clamp (the Product or Clamp) is a handheld, battery-operated clamp that measures the ground resistance without auxiliary ground rods and AC leakage current. The Clamp is used in multi-grounded systems without disconnecting the ground under test.
The Clamp supports these applications:

  • Earth resistance and AC leakage current tests of high voltage pylons, buildings, cell phone substations, and RF transmitters
  • Inspection of lightning protection systems

The 1630-2 FC supports the Fluke Connect Wireless System (may not be available in all regions). Fluke Connect is a system that wirelessly connects your Clamp with an app on your smartphone or tablet. The app shows the ground resistance measurements on your smartphone or tablet display. You can save these measurements and images to Fluke Connect Cloud storage and share with your team. For more information, see Fluke Connect Wireless System.

How to Use the Clamp

This section is about how to set up the Clamp for Earth resistance tests, AC leakage current measurements, and the Fluke Connect Wireless System.
The Clamp includes a trigger lock on the trigger. Push the jaw trigger lock and trigger together to open the jaw.

Ground Resistance Measurements

The Clamp generates a voltage to the system under test and the induced current in the system is measured by the Clamp. The Clamp uses Ohm's Law (R=U/I) to automatically calculate the resistance measurement.
To check the Clamp before ground resistance measurements:

  1. Position the Jaw on the Standard Loop Resistance. See Figure 7.
    Standard Loop Resistance
  1. Verify that the display reading is within specification, see Table 4.
    • If the reading is not within specification, clean the heads of the Jaw and repeat step 1 and step 2.
    • If the reading is within specification, remove the Jaw from the Standard Loop Resistance. The Clamp is ready for a ground resistance measurement.
      Table 4. Display Reading Specifications
      Input (Ω) Minimum Maximum
      0.474 0.417 0.531
      0.5 0.443 0.558
      10 9.55 10.45
      100 96.0 104.0

For ground resistance measurements:

  1. Open the jaw and make sure the jaw is free of dust, dirt, or any foreign substances.
  2. Turn on the Clamp.
  3. Push to select the Ω function.
  4. Attach the Clamp to the electrode or ground rod to be measured.
  5. Read the value of Rg (ground resistance) from the display. Figure 8 illustrates the ground resistance measurement principles.
    Ground Resistance Measurement Principles

Note

  • If >3 A is found in the ground rod, NOISE shows on the display and the Clamp beeps. When noise is present, the Clamp reading is not valid.
  • If the jaw assembly is opened during measurement, shows on the display.

AC Leakage Current Measurement

Based on the electromagnetic induction principle, the Clamp has a ring-shape current transformer comprised of a metal core and coil winding. The current transformer senses the magnetic field produced by the current or by the vector sum of the currents flowing in the conductor under test. The current transformer then produces a current proportional to the current flowing in the conductor.
For an AC leakage current measurement test:

  1. Open the jaw and make sure the jaw is free of dust, dirt, or any foreign substances.
  2. Turn on the Clamp.
  3. Push to select the A function.
  4. Attach the Clamp to the electrode, conductor, or ground rod for measurement. Figure 9 shows several connection types for an AC leakage current measurement.
    AC Leakage Current Measurement
  5. Read the value of the leakage current on the display.

Logging Measurements

The Clamp records data over time and saves >2000 measurements in memory at the set logging interval.
To start logging measurements, push . The display shows to indicate that measurement logging is in progress See Figure 10.
Logging Measurements
Measurements are recorded at the sampling interval you specified. See Log Interval for more information.

Logging stops when:

  • Clamp memory is full
  • Clamp detects a low battery
  • You push again

Note
If the sampling interval is set at 0 seconds, only one data point is recorded. To record the next data point, press again. The memory location is also displayed for about 1 second.

Hold

Push to freeze the measurement value on the display.
Push again to continue and take measurements.

Filter

Push to toggle the filter on and off in the leakage current measurement mode. When shows on the display, the clamp can isolate the 50/60 Hz fundamental frequency from the harmonics.

Fluke Connect Wireless System

The 1630-2 FC supports the Fluke Connect Wireless System (may not be available in all regions). Fluke Connect uses low-power 802.15.4 wireless radio technology to connect the Clamp with an app on your smartphone or tablet. The wireless radio does not cause interference with meter measurements.
The app shows measurements from the connected Clamp on your smartphone or tablet display, saves to Fluke Connect Cloud™ storage, and shares the information with your team.
