NEMA or the National Electrical Manufacturers Association has developed rating standards for electrical enclosures to ensure safety, compatibility and proper function of electrical products. These ratings provide the standards that help in defining the types of environments in which various electrical enclosures can be used. NEMA ratings frequently indicate a fixed enclosure's ability to withstand [...]
The use of electricity undeniably increases during winter and this makes it inevitable to remain extra vigilant when it comes to electrical safety. As winter approaches several power issues crop up due to strong winds, snowfall and heavy rains. Accidents involving electricity can prove to be extremely fatal and also have financial repercussions. Fortunately, if [...]
DC motors are electrical devices which draw electricity (direct current) and convert it into mechanical energy. They have many uses in today’s industries, even though alternating current is the preferred choice for mains power supply. They are especially useful for machines that need to be driven at variable speeds. DC motors are easy to miniaturize, [...]
Safety switches are devices that monitor the movement of current through electrical wiring and disconnect the supply of electricity upon detecting differences or imbalances. They react to even the tiniest change within a fraction of a second, cutting off the power if there’s a leak of electricity to ground, a power board is overloaded, etc. [...]
It is crucial to have proper electrical connections in your home, office or place of business since faults or failures in the system pose a serious risk in terms of electrocution, fire damage and short circuits. Whether you’re working in the electrical industry or tackling a project on your own, or planning to move out [...]
Much like overhead transmission lines, underground electrical cables and other ancillary facilities can experience problems if they aren’t properly maintained. For instance, High Pressure Fluid and Gas Filled Pipe (HPFF and HPGF) cable types or Self-Contained Fluid Filled (SCFF) electrical cable types are prone to developing fluid leaks. Buried power cable wires can also develop [...]
The Need for Circuit Breakers Whether it is a residential structure or a commercial building, everyone is exposed to electric hazards from domestic appliances, plant equipment and machinery. Shocks and burns from faulty plant equipment can result in lifelong damage and cause serious injuries. Circuit breaker protection is used along with grounding for protecting electronic [...]
Power cables are the basic components of any electrical system. There are different types of cables that are available in the market. The choice of which specific cable types should be used for specific purposes is based on several factors, the most important of them being the technical specifications of the functions. As much as [...]
The use of underground cables for transmission of power dates back centuries. However, the usage of these cables has remained relatively low in different regions of the world. The basic idea behind the use of underground cables is that electrical power can be transmitted in two main ways: by use of overhead electrical cables or [...]
When cool surfaces are exposed to warm, moist air, condensation occurs. Condensation is characterized by the cooling of surfaces after coming in contact with warmer air in their surrounding environment. Electrical enclosures are prone to condensation, as they are exposed to temperature fluctuations. The remedy for this danger is the installation of thermal insulators, especially [...]
