Each year many electrical equipment’s defected due to surge voltage from natural disaster like lightning or supply error.It very costly to replaced it back to normal system. Theoretically single lightning strike produce 20,000 to 40,000 Ampere and about 200 Mega volts (MV) .It enough to generated a temperature about 4 times hotter than the surface of the [...]
For electrical power distribution,substation is the one important component to serve,distributing and regulated an electricity to building,factory or private living area. Normally substations have the several required equipment such as power transformers and the voltage-regulating device for converting the high incoming sub-transmission voltages to low voltage primary system and ensure it in specified voltage tolerances. [...]
What is the surge voltage?For our easy understanding,electrical surge is a sudden high pick out of voltage value in the system.It can happened in electrical power distribution and communications lines entering homes,factory, offices, and other facilities. The surges voltage happened due to natural factor such as lighting or human error.It can effected and can cause [...]
When design the electrical installation and electric power for building or factory,the main objective that we need to focus is about emergency and standby electric power systems.The main reason is the about safety of building occupants following a power outage. When danger or disaster happened at building or factory such as fire,heavy smoke, chemical hazard,tsunami [...]
Batteries is one of the common thing in our daily application.We used it for domestic and industrial application.It can stored the electricity energy to made our equipment function properly. We need to choose the suitable type of battery system depend on our application and design to ensure it can operated with maximum capacity.It have in [...]
This energy come from sun.It send a enormous amount of energy.It totally free and clean source.Now the solar energy become the alternative green house technology for electricity generation.It call the green technology.It not pollute the environment and not accumulate any hazardous waste. Day by day,cost to produce electrical energy increase and its the main factor why more [...]
This part is important to us when suddenly our electricity cost is higher than normal usage.We can determine the figure from electrical supplier is correct or not We also can calculated a electricity cost for estimated our new electrical design such as install new motor,compressor,furnace or others equipment.With this calculation we can know the estimated [...]
