All about structural earthing system

 The metallic structure used to carry the current will be first hit by lightning or faulty current whenever there is a power outbreak, or a fault occurring in the equipment attached to the structure. Thus, the structure needs to be protected. The structure is required to have a low-impedance path to the grounding system so that the faulty current can be transferred safely to the ground within seconds. Thus, structural earthing is preferred for non-electrical equipment. 

A conventional earthing is an independent system where a dedicated earthing conductor is connected between the metallic structure and electrical equipment to the earth pit. The size of the earthing conductor depends upon the magnitude of the current flowing. 

The pros and cons of structural earthing. 

Pros: 

• Structural earthing is quite economical and it doesn’t involve any dedicated earthing. 

• It is easy to maintain. 

• Structural earthing has a good life span and it doesn’t have any complex network. 

• There is no additional area required to conduct the earthing process. 

Cons: 

• This type of earthing is only recommended for non-electrical equipment. 

• It is not considered a superior conductor to carry the fault current. 

The choice between structural earthing and conventional earthing narrows down your requirements. Whatever you choose, if you need tools such as shoulder eye bolts or socket eyes, you can reach out to us.

How grounding saves us

We are using the power of lightning for our daily use. They sure provide convenience, but the fact remains that we can have danger from them whenever there is lightning or there is an excess flow of energy. When there is an outlet to the ground for excess electricity to flow out it will keep us safe. That is how grounding saves us. There are many chances of getting exposed to electric shocks if the ground is not done properly. Like if a water pipe made of copper crosses the path that can cause a problem. It is therefore important to make sure that proper guidelines are followed to ensure that overvolt is controlled. Electrical grounding can either be directly connected t the ground or it can unground and connected through a capacitance. There are advantages and disadvantages to an ungrounded system, but the one connected to the ground is the safest. The most important thing to do before entering the house is to set up an inspection for electrical safety. Make sure all the parameters a...

Key perks of proper grounding

 In this article we are going to look at some of the key perks of proper grounding. We are going to see how proper grounding can keep yourself, your family and your house and the electrical and electronic components of the house safe from any kind of electrical anomaly, such as a sudden surge in the voltage of the house or lightening strike.  One of the most important advantages or benefits of opting for proper grounding is that it can eliminate the hazard of an electrical shock caused by someone touching an electrically charged or energized surface of an equipment or a conducting surface of an equipment.  This is one of the most important advantages of opting for proper grounding. It can keep the residents of the building safe. Whenever there is an electrical anomaly in the building, the conducting surfaces can become electrically charged and it can be extremely dangerous.  Secondly, grounding when properly done and ensured, ensures the safety of your electronic it...

Consequences of improper grounding

Not having a failsafe earth testing or grounding system in place can lead to disastrous effects in the future. This can also invite expensive equipment replacements, leading to loss of mission-critical data. It can further put both life and property at a huge risk. When any important equipment is left without proper earthing or grounding, it can experience damaging voltage surges and spikes. Thus, you need to not only be careful while putting the earthing in place but also have sufficient systems for earth testing as well. In case you need more anchor rods or helical anchors , you can talk to us. Alternating failures can invite problems from random shocks that leave your equipment out of order. Such failures are also difficult to diagnose as the actual cause of the failure is nothing but lack of ground testing. For example, when random shocks were experienced in the shower area of a fire station, extensive testing revealed that a part of the structure started operating like a capacito...
