What are Common Electrical Hazards at Work Place?

  It is very important to understand your workplace and the available hazards or risks in the place. We have to ensure that our workplace is safe and personally take responsibility for keeping it safe. You might be working in developed nations like the USA, Saudi Arabia, Qatar, UK, United Arab Emirates Kuwait, or developing countries like India, Brazil, the Philippines, or any other nations. Irrespective of the country your workplace is located it's the responsibility of the employer to provide a safe working environment as per OSHA regulations and the responsibility of the employee to understand the available risk and follow the rules and apply the risk-mitigating techniques as per the international standards and regulations. The main hazards of working with electricity are electric shock and  burns  from contact with live parts. Injury From exposure to arcing,  fire  from faulty electrical equipment or installations. Electric shock   Exposure to Arc-Flash Exposure to Arc-Blast

How to do Industrial Earthing for Electrical Equipment?

These are the two burning questions in every electrical maintenance engineer mind. Electrical earthing system design in industries plays a vital role in protecting the equipment and workmen from damage. We need to determine the number of layers by conducting a proper soil resistivity test for the proper design of earthing. A traditional design of earthing, considering uniform layer structure may not always be applicable. Substations in the electrical networks and transformer yards in the facility require high beamed earthing. We also need to ensure that our earthing system is safe and economic as well. The optimal designing of the system using simulation techniques and IEEE-80 sheets will facilitate us with the proper and safe earthing.

Earthing is the method of transmitting the instant electricity discharge directly to the ground through low resistance wires or electrical cables by providing an easy path to dissipate the current to the ground. This is one of the significant features of electrical networks. Because it builds the most eagerly accessible and risky power source much secure to utilize.

Various Types of Electrical Earthing Systems
The complexity in the earth layers and various kinds of industrial sites demand different type of earthing practice. A standard and traditional earthing may not work for all types of sites. The process of Earthing or electrical grounding can be done in several ways like wiring in factories, housing, other machines, and electrical equipment. these are the different types of electrical earthing systems

Plate Earthing System
In this type of system, a plate is made up of copper or GI (galvanized iron) which are placed vertically in the ground pit less than 3meters from the earth. For a better electrical grounding system, one should maintain the earth moisture condition around the plate earthing system.

Pipe Earthing System
A galvanized steel based pipe is placed vertically in a wet is known as pipe earthing, and it is the most common type of earthing system. The pipe size mainly depends on the soil type and magnitude of current. Usually, for the ordinary soil, the pipe dimension should be 1.5 inches in diameter and 9feets in length. For rocky or dry soil, the pipe diameter should be greater than the ordinary soil pipe. The soil moisture will decide the pipe’s length to be placed in the earth. The pipe earthing diagram is shown below:

Rod Earthing System
This type of earthing system is similar to pipe earthing system. A copper rod with galvanized steel pipe is placed upright in the ground physically or using a hammer. The embedded electrodes lengths in the earth decrease the resistance of earth to a preferred value.
