What are low voltage systems, and are these successful?


Most of us are only aware of the low voltage systems that can trip electrical gadgets and make our lives difficult. Right? But with the advancement in technology, electrical engineers have come up with low-voltage power systems that prove to be an efficient alternative for regular high-voltage power systems.

What is a Low Voltage System?

In simpler words, low voltage system refers to an electrical system that operates at a significantly lower voltage than the power distribution system. Basically, low-voltage systems are designed for a set of applications that are characterized by their voltage levels. Low voltage level systems are often less than 50 volts (V) or 120 volts (V) direct current (VDC). Low voltage systems are used for different purposes and are typically safer and more energy efficient than high voltage systems.

Characteristics of the low voltage system:

Now that we know such systems exist in the electrical world, our next question should be regarding the main characteristics of low voltage systems. So, here are the main features:

  • The low voltage systems run on 30 volts DC or lower voltage.
  • Besides, they are powered through a Class 2 Power source
  • These systems are easy to install, manage and inspect.
  • The compliance code for electric gadgets is lenient when it comes to the low voltage system.

Are we using them practically?

Airplanes, boats, and other vehicles use the DC or low voltage current system for powering all the electrical pieces of equipment.

In the buildings and houses, we are still using a combination of high and low voltage electrical systems but haven’t moved entirely to low-voltage.

Are low voltage systems effective?

Yes, the low voltage system is more efficient and reliable when used for powering our daily electric gadgets. However, the mainline transmission and certain equipment like pumps cannot use the low voltage, as they require high voltage for the operation.

But for the rest, we can shift to low voltage. One thing to note here is that moving to low-voltage systems in chunks won’t be feasible as it would require the complete system for proper functioning, and this is why we’ll have to focus on the transformation of the entire building from high to low-voltage.

One of the practical examples that we can see around us is the use of LED lights. They work on a lower voltage and are capable of working properly for our needs. Besides, they consume less electricity and produce less heat, which reduces the risk of wiring failure and other such issues.
