Projekt systemu uziemienia-A \u201cgrounded\u201d electrical device is one that connects to a grounding system for safety reasons. Grounding finds a path that\u2019s safe or offers the least resistance to stray voltage. It ensures the stray voltage doesn\u2019t build up in a place where it could be dangerous. Instead, you divert it to the desired path where it can discharge safely. Discharging into the ground doesn\u2019t endanger anyone. Overall, a grounding system is imperative for electrical safety. It\u2019s a ground setup with conductors put into the earth. Even if a massive power surge or lightning strike occurs, a\u00a0 proper grounding system design will protect your home.\u00a0<\/p>\n\n\n\n
Projekt systemu uziemienia-The Importance of a Grounding System<\/strong><\/h2>\n\n\n\n
Electrical grounding is a vital part of any installation, and you\u2019ll find it at industrial properties, generation sites, and substations. Here are the benefits of a great electrical grounding design:<\/p>\n\n\n\n
Grounding can avoid voltage from reaching other conductive materials that could make it dangerous, such as water or metal. So, it\u2019s imperative for personnel safety, and it reduces the risk of accidents.<\/p>\n\n\n\n
Additionally, grounding stops voltage from overloading and thus damaging your appliances, which helps them last longer and function better. So, it keeps electronic equipment safe and prevents potential issues.<\/p>\n\n\n\n
The risk of a ground fault current and the problems it causes are minimal. so, you can save money you\u2019d spend on expensive repairs.<\/p>\n\n\n

What Affects the Grounding System Performance?<\/strong><\/h2>\n\n\n\n
Grounding study requires complex calculations. Therefore, only engineers should do it. They\u2019ll focus on these factors:<\/p>\n\n\n\n
Soil characterization and its specifics<\/p>\n\n\n\n
The duration and magnitude of the ground fault current<\/p>\n\n\n\n
Shape and design of the grounding system<\/p>\n\n\n\n
The design should cover all gear, including sensitive equipment. Many engineers use software to help them when calculating these variables.<\/p>\n\n\n

Projekt systemu uziemienia-When Should You Do a Grounding System Study?<\/strong><\/h2>\n\n\n\n
Did you install a new power setup? If yes, you must conduct a grounding study as soon as possible.<\/p>\n\n\n\n
As for existing systems, here is when a study is necessary:<\/p>\n\n\n\n
You noticed something is off during maintenance<\/em><\/strong>. Did a wire corrode, or is something missing? Perhaps your measurements revealed a problem. Either way, getting a ground study can improve safety.<\/p>\n\n\n\n
Short circuit duty replacements<\/em><\/strong>. Did you add or replace a transmission line or? Even if you only have a new circuit breaker, you\u2019ll need a new study, too.<\/p>\n\n\n\n
Fence and gear changes<\/em><\/strong>. Did you move the fence to another position? Is your equipment in a new place or a new gear on the site?<\/p>\n\n\n\n
Missing documentation<\/em><\/strong>. If you don\u2019t have info from the previous study, a new one can help to reduce the risk of issues.<\/p>\n\n\n

Steps Included in the Grounding System Design & Planning<\/strong><\/h2>\n\n\n\n
The basic principles of a grounding study start by checking the current limits that the system should handle. So, any voltage that can occur during a shouldn\u2019t be a problem. <\/p>\n\n\n\n
Projekt systemu uziemienia-See how many safety grounding setups the property needs<\/strong><\/h3>\n\n\n\n
Here is a table that experts across the United States use:<\/p>\n\n\n\n
A building must have at least two groundings to prevent electric shocks and other problems. If the ground level is less than 250 feet, two setups at diagonal corners will do.<\/p>\n\n\n\n
If the property\u2019s ground level is over 250 feet, the third grounding setup will be additional protection.<\/p>\n\n\n\n
Add another grounding setup per every 100 feet. So, if the ground level is 250-350 feet, you\u2019ll have three. On the other hand, if it\u2019s 351-450 feet, you\u2019ll need four, etc.<\/p>\n\n\n\n
Do you notice that metal covers the property? Make sure there is a complete lightning protection system. Additionally, check that the cables don\u2019t have \u201cv\u201d or \u201cu\u201d pockets. They shouldn\u2019t have sharp turns. Instead, place them down on the ground or horizontally. You might need a\u00a0 to suit your needs.<\/p>\n\n\n\n
Here are some other tips for maximum safety benefits:<\/p>\n\n\n\n
Never use aluminum below the ground. Additionally, don\u2019t use it on copper surfaces, such as roofs.<\/p>\n\n\n\n
Don\u2019t interconnect aluminum and copper conductors. The only exception is if you use bimetallic connectors.<\/p>\n\n\n\n
Don\u2019t use copper conductors on aluminum surfaces, such as roofs. Additionally, don\u2019t use it on bare galvanized steel.<\/p>\n\n\n\n
Projekt systemu uziemienia-Collecting Data<\/strong><\/h3>\n\n\n\n
It includes geological and. The experts often use them because it\u2019s accurate. You can use existing ground systems for extra data. Make sure to be thorough when collecting info. The more reliable data you gather, the better the final result will be.<\/p>\n\n\n

Analyzing Data<\/strong><\/h3>\n\n\n\n
Once you gather the available info, it\u2019s time to analyze it. Most engineers use pro software to get a soil model. It will show the resistance of the soil in ohm meters. Furthermore, it will specify the resistivity at many depths. Therefore, you\u2019ll know where the most conductive soil is. That will make it easier to design a system in line with the expectations.<\/p>\n\n\n\n
The resistivity can vary depending on the materials. Additionally, wetter surfaces will have higher resistance than dry ones. Minerals, temperature, and electrolytes also affect the resistivity rating.<\/p>\n\n\n
