Benning 044113 Earthing Set Instruction Manual

1. Product Overview

The Benning 044113 Earthing Set is designed to complement the Benning IT 120 B Insulation Resistance Test Instrument, enabling precise ground resistance measurements. This set facilitates the three-conductor method for accurate earth resistance testing, crucial for electrical safety and system integrity.

The complete set includes three specialized test lines and two robust earth stakes, providing all necessary components for conducting reliable ground resistance tests.

2. Components

The Benning 044113 Earthing Set contains the following items:

• 1 x Blue Test Line
• 1 x Green Test Line
• 1 x Black Test Line
• 2 x Metal Earth Stakes

This image displays all components of the Benning 044113 Earthing Set. From top to bottom, there is a blue test cable, a green test cable, a black test cable, and two silver-colored metal earth stakes. Each cable is neatly coiled and secured, with connectors visible at their ends. The earth stakes are L-shaped at one end for easy insertion into the ground.

3. Setup and Connection

Before performing any measurements, ensure the Benning IT 120 B Insulation Resistance Test Instrument is powered off and disconnected from any live circuits. Follow the instructions provided with your IT 120 B for specific connection points.

1. Prepare the Test Site: Select a suitable location for your ground resistance measurement. Ensure the area is clear of obstructions and that the ground is moist enough for good contact.
2. Insert Earth Stakes: Drive the two metal earth stakes into the ground at appropriate distances from the earth electrode under test, as specified by the three-conductor measurement method (typically 5-10 meters apart, or as per local standards).
3. Connect Test Lines:
   • Connect one end of the blue test line to the potential terminal (P) on the IT 120 B and the other end to the potential earth stake.
   • Connect one end of the green test line to the current terminal (C) on the IT 120 B and the other end to the current earth stake.
   • Connect the black test line to the earth terminal (E) on the IT 120 B and to the earth electrode being tested.
4. Verify Connections: Double-check all connections to ensure they are secure and correctly aligned with the terminals on the IT 120 B and the earth stakes.

4. Operating Instructions

Once the Earthing Set is correctly connected to the Benning IT 120 B and the test site is prepared, you can proceed with the ground resistance measurement.

1. Power On: Turn on your Benning IT 120 B Insulation Resistance Test Instrument.
2. Select Measurement Mode: Navigate to the ground resistance measurement mode on your IT 120 B. Refer to the IT 120 B's manual for specific menu navigation.
3. Initiate Test: Press the test button or activate the measurement function on the IT 120 B. The instrument will send a test current through the earth stakes and measure the resulting voltage drop to calculate the ground resistance.
4. Record Reading: Note the resistance value displayed on the IT 120 B.
5. Repeat Measurements (Optional): For greater accuracy, it is recommended to perform multiple measurements at slightly varied stake positions or distances, then average the results.
6. Power Off and Disconnect: After completing measurements, power off the IT 120 B and carefully disconnect all test lines and remove the earth stakes.

Important: Always adhere to local electrical safety regulations and the specific operating instructions of your Benning IT 120 B instrument.

5. Maintenance and Storage

Proper maintenance and storage will extend the lifespan of your Benning 044113 Earthing Set.

• Cleaning: After each use, wipe down the test lines and earth stakes with a clean, damp cloth to remove any dirt, moisture, or residue. Ensure they are completely dry before storage.
• Inspection: Regularly inspect the test lines for any signs of damage, such as cuts, abrasions, or frayed insulation. Check the connectors for corrosion or bending. Inspect the earth stakes for bending or excessive wear.
• Storage: Store the earthing set in a clean, dry environment, away from direct sunlight and extreme temperatures. Coil the test lines neatly to prevent tangling and damage. The original packaging or a dedicated carrying case is recommended for protection during transport and storage.
• Avoid Harsh Chemicals: Do not use abrasive cleaners or solvents on any part of the set, as this may damage the materials.

6. Troubleshooting

If you encounter issues while using the Benning 044113 Earthing Set, consider the following common troubleshooting steps:

• No Reading or Erratic Readings:
  • Ensure all connections to the IT 120 B and earth stakes are secure and correct.
  • Check the condition of the test lines for any breaks or damage.
  • Verify that the earth stakes are driven deep enough into the ground to make good contact.
  • If the ground is very dry, moisten the area around the earth stakes to improve conductivity.
  • Confirm the IT 120 B is set to the correct measurement mode.
• Difficulty Inserting Earth Stakes:
  • If the ground is too hard, try moistening it or selecting an alternative spot.
  • Ensure the stakes are inserted vertically to minimize bending.

For issues related to the Benning IT 120 B instrument itself, refer to its dedicated instruction manual or contact Benning customer support.
