While high voltage electric is suitable for transmission lines and factories that use too much power, most electrical devices in our homes and offices run on low voltage. The use of low voltage direct current has so much to offer. For example, using ELV SYSTEMS devices lowers costs and increases safety. Low voltage electrical supply also improves energy efficiency. Most sources of renewable energy, including solar, hydro, and wind all provide low direct current power.
However, some devices use a combination of low and high voltage to increase performance. Although this is the case, the balance is shifting towards low voltage systems, especially when it comes to lighting. The introduction of light-emitting diodes is a good example of this shift. Track and cove lighting used for accent lighting is also an example of the changing balance.
ELV SYSTEMS are also becoming popular since they produce less heat than high voltage electric systems. Heat reduction allows us to save energy by reducing the need for cooling.
Installing low voltage wiring is also less hectic than high voltage wiring. Any skilled electrician can install low voltage wiring. The good thing is that installing low voltage wiring is much safer than high voltage wiring.
Low voltage lighting also preserves back-up batteries since they run on low power. Moreover, some light-emitting diodes have emergency backup drivers.
