Every year, new models of electronic equipment, increasingly sophisticated and expensive, abound on the market. This technological advance has created a significant power protection problem.

There are many ways to carry out power protection. Some of these systems work by isolating faults from the entire electrical network, while other, simpler systems work by simply regulating the supply voltage. The main purpose of all these devices is to protect all your sensitive equipment including computers, routers, fax machines and many more. No one can just take this for granted.

The most common and simplest form of power protection is the built-in fuse found inside the machine or equipment. This fuse is designed to allow only a certain current of power to flow to your machine. If the current flow is higher than the declared value, the fuse will burn automatically. This system cuts the circuit, thus protecting other parts of the machine from burning out. A 110 volt rated machine will blow its fuse if you plug it into a 220 volt outlet.

The next simplest form of protection is the automatic voltage regulator, or AVR. The AVR works by ensuring a stable and constant supply of output voltage. This simple device is responsible for preventing overheating of your equipment or machine. These voltage regulators are sure to help address voltage spikes or fluctuations in specific areas of your machine. There are different types of automatic voltage regulators. There are voltage regulators that are connected to the machine itself, like computers, and there are those that are connected to the electrical network.

Of course, like any product of technology, automatic voltage regulators also have their advantages and disadvantages. A stand-alone portable AVR would cost less initially, but it won’t be as reliable as more expensive heavy-duty units. While the use of heavy devices can be economical in the long run, the large initial cash investment to purchase them cannot be ignored.

On a larger scale, power protection is considered a branch of electrical engineering. It is basically about electrical networks and their protection. It has five components. The first component is the transformer. Transformers are used to step down or step up voltages to meet the requirements of the relays.

The second component is the relay. The relays are used to detect a line fault. They are responsible for activating a trip on the breakers each time a fault is detected. The third component is the circuit breaker. Its main function is to open or close the circuit according to the commands of the relay. The fourth component is the battery. Batteries are used to supply power in the event of a power failure in the system. The last component is communication. Communication is necessary so that remote triggering can be performed on the equipment.

These protective devices are designed to protect your machine assets and ensure uninterrupted power supply. They are mainly installed as a precautionary measure, since electrical failures can occur at any time. There are many reasons for electrical failures. These are insulation failures, transmission line failures, circuit breaker malfunctions, and short circuits.
