Electricity is a staple in most homes today, and our reliance on it means that it’s important to learn how to handle it safely. Unfortunately, electrical fires and shocks aren’t as rare as you might think, but the good news is that most of them are completely preventable. By keeping a few basic ideas in mind, you can safeguard your home from electrical hazards and still enjoy helpful appliances and beautiful light fixtures!

There are several different types of medium voltage earthing systems. These systems can be differentiated by using the neutral point connection method. They are different in the way that they operate and each of them has its own pros and cons. These earthing systems in medium voltage include the likes of:

The functioning of each differs from the other. They also have various applications. Let’s have a look at each system at a time:

In this one, there is no electrical connection between the earth and the neutral point except for the devices that are used for measurement or protection. There is high impedance inserted between the earth and the neutral point. There is no switching on occurrence of the first insulation fault. It is therefore important to carry out permanent insulation monitoring, show the first insulation fault and locate and clear the first insulation fault.

Pros and cons: The advantage of using this one is that it provides services by tripping only when the second fault occurs which is subject to the capacity of the network not leading to a high earth fault current which would be dangerous for people when the first fault occurs. It has its demerits. There is the risk of high internal over-voltages. Insulation monitoring is also compulsory as well as the presence of maintenance personnel who will be monitoring and locating the first fault during use.

It is also known as direct earthing. It has a connection between the earth and the neutral point. Upon first insulation fault occurrence compulsory switching must be done. It is significantly different from the above mentioned unearthed neutral.

Pros and cons: This system reduces risk of over-voltage occurring and also authorizes the use of equipment with a normal phase to earth insulating level. On the other hand, there is mandatory tripping upon occurrence of the first fault. The touch voltages developed are very high and this poses a high risk for the personnel while the fault lasts. Differential protection devices must be used so that the clearance time of the fault is as short as possible.

This system requires a resistor to be inserted between the neutral point and the earth. It is also known as limiting resistance earthing. Their operating technique is quite straightforward. Switching must be done upon the occurrence of the first fault.

Let’s face it—halogen and incandescent headlight bulbs are a thing of the past. fanless, driverless LED headlight bulbs were used in this installation.

If your vehicle allows for horizontal adjustments, mark the distance between your headlight centers with two vertical lines of tape. These lines are important for projector headlights and/or lining up beam cutoff points. Repeat these tape lines for your other headlight.

6. Remove your headlight assembly if necessary, remove the current bulbs, and install your new LED bulbs. Check your owner’s manual for specific instructions on how to replace your headlight bulbs.

7. Depending on your vehicle, you may have to adjust your headlight beam before or after the assembly has been reinstalled. Your owner’s manual will explain how to adjust the beams. Align each headlight so that the top edge of the beam is at the same height as your horizontal line(s). If your headlights can be adjusted horizontally or produce two light cutoff points, use the vertical tape lines to align them properly.

3. Shake the vehicle to ensure that your suspension system is settled. For more precise adjustments, inflate all tires to their designated psi capacity and have someone sit in the driver’s seat. Also, make sure that your vehicle’s gas tank is at least half full.

4. Measure from the ground to the center of your headlight assembly where the bulb is located. This step must be done for all vehicles. If your vehicle allows for horizontal headlight adjustments in addition to vertical adjustments, it’s important that you also measure the distance between the centers of both headlight bulbs. The vehicle featured in this video allows for vertical headlight adjustments only; therefore, center lines aren’t necessary but are shown for demonstration purposes.

5. Turn on your low-beam headlights. Using painter’s tape, mark your headlight measurements on a flat wall. Measure from the ground up, and apply a horizontal line of tape to the wall; this line represents the top of your headlight beam. You can either apply one long, continuous line or small sections where the brightest areas of the headlight beams are shown.

If your vehicle allows for horizontal adjustments, mark the distance between your headlight centers with two vertical lines of tape. These lines are important for projector headlights and/or lining up beam cutoff points.
