The mesh size in the earthing design for substation can be various size depend on the area. For area that does not contain equipment, we could increase the mesh size because there is no equipment to cause touch potential. But if the area is at the corner of the substation, the mesh size should be smaller because to limit the step potential.

Design Patent Search?
Anyone desiring to secure a patent upon his or her special design will need to perform a design patent search. Design patents are reserved for a special category of physical items under law. Laws for design protection vary by country around the globe. In the United States, the ornamental design that is on a functional item can be granted a design patent. A design patent can only be granted for a unique ornamental design of an item that is functional. Examples include computer icons and other computer images, beverage containers, jewelry and furniture. This patent is also a form of an industrial design right, enforceable by law. Design patent attorneys are able to register with the government as an agent or attorney specializing in patent applications after they pass a registration examination offered by the U.S. Patent and Trademark Office. Foreign countries have their own form of a design patent and application procedure. To consider another design to be an infringement upon a design patent, it only needs to be shown that another design is similar to the patented design; it does not need to be an exact copy. The inventor, a patent attorney, or registered patent agents are the only ones who are allowed to prosecute design infringement or to file a design patent application. Most design patent applications contain a transmittal, a specification, some drawings and a declaration. The design patent application will not be published in the United States and several other countries until it is granted. It is very important to maintain secrecy until the patent is granted. Design patent searches are made to determine that the new design does not infringe upon another patented design. Most patent design searches and applications are done by patent attorneys to ensure that all legal aspects of the process are performed correctly. Design patents are valid for a period covering 14 years following the issue date. This type of patent is only for the ornamental nonfunctional design of a functional item. Some items that have a design patent may also have a copyright or a trademark. Each separately protects from being copied under penalty of law. There are 33 categories of items that can be granted a design patent in the United States. Items include apparel, packaging, musical instruments, games, toys, lighting, cosmetic products and many other items that can incorporate unique nonfunctional designs. (A chart showing all categories can be viewed at: http://www.freepatentsonline.com/design-patents.html.)
What is a design modification?
A design change is the modification conducted to the product. It can happen at any stage in the product development process. The design changes that happen early in the design process are less expensive when compared to those that take place after it is introduced into full-scale production.
What is embossing?
Embossing is the process of creating raised design in a material. Debossing is the process of creating a recessed design.
Design of earthing calculation 132 kv switch-yard?

What is earth mat technique is for earthing of electrical system?
Earthmat design is a technique for improving earthing points.It is used at those places where burying ground rods is not possible
What is the difference between chemical earthing and conventional earthing?
Chemical Earthing and Conventional Earthing are different types of earthing techniques. Conventional Earthing is based on plate earthing and pipe type earthing but Chemical Earthing on GI or Copper.
What compose a transformer substation?
A transformer substation comprises of transformation equipment- the transformers, the accessories for the connection of the transformers to the HT Lines (Primary Input)- usually concrete poles/steel towers, insulators etc; normally two or more transformers are present to allow maintenance and faults without the supply being interrupted. 2. The substation protective equipment such as lightning Arresters, Line Fuses and Breakers, Isolators (as appropriate) 3. Effective Earthing system and equipment 4. The Distribution equipment such as feeder pillar units, busbars etc depending on the type of transformer substation.
What is a mini-substation?
A substation that is smaller than the average substation. A substation converts electric power from one voltage to another.
What is pooling substation?
The Substation which comes power from the power plant know as pooling substation.
Why flooring of substation is done with stones?
Substations usually use crushed limestone in the ground design to help minimize GPR (ground potential rise) within the substation. Without getting too technical, it helps keep the step and touch potential within limits so people working in the substation aren't hurt.

What is the difference between earthing boss and earthing lug and where to use?
An earthing boss and earthing lug are parts of a grounding connection. An earthing boss is in a casting that allows for the drilling and tapping of hole. A earthing lug is used to bond a wire to the ground.
