Rating of the best network filters for 2022

In the modern world, it is hard to imagine life without electronic devices. In any case, every house or apartment is equipped with electronics, since the use of such equipment facilitates everyday tasks and makes life more comfortable. In order for the equipment to function flawlessly, you need to take care of reliable wiring and stable voltage. The problem is that low-quality electronic components can quickly fail, which will lead to undesirable consequences. In this article, we will look at the best surge protectors of 2022 that guarantee safety and reliability during use.

The principle of operation of the network filter

The mains filter is designed to protect electronic devices during power surges. The service life of devices depends on the quality of the node. Any household appliance at the first start produces a high load on the network, which can subsequently lead to unforeseen circumstances - burnout of light bulbs, knocking out traffic jams, etc. Such consequences arise if a number of powerful devices are involved in the apartment. It is in this case that a surge protector is needed, which will redistribute the load and protect the network from surges.

The mains filter is characterized by a rather complex design, which, first of all, distinguishes this unit from a tee and an extension cord. The fact is that the filter has a varistor, which is responsible for reducing the resistance. If the varistor does not cope with its task, then a fuse comes to replace it, which is available even in the cheapest devices. They also effectively protect electronic equipment from power surges. If the voltage drop is too high, the current limiter comes into play, which disconnects the equipment from the network.

In addition to the varistor and fuse, the mains filter is equipped with a capacitor and a symmetrical type choke. The last element serves to smooth out interference in the network. It is worth noting that another important part of the described device is grounding, since without it the filter would be no different from an extension cord.

Criterias of choice

A good choice of surge protector can ensure that certain criteria are met. When buying, you need to pay attention to the following factors:

Appearance and length of the device

In addition to protecting the network from power surges, the filter must be productive.When buying protective equipment, you must first determine the length of the wire. The number of outlets and the presence of a USB port also play an important role. Do not deprive attention of the quality of the insulating material and the type of case. It is also worth taking into account the dimensions of the filter, the mounting system and the number of holes required to connect the electronics.

Degree of voltage filtering

All electrical appliances are designed for operation during which a voltage of 220 V will be used. However, from time to time the rate of the indicator is significantly exceeded. This is a serious problem faced by most consumers. The main problem is that the jump cannot be determined visually, so special measuring instruments must be used. As for the jumps themselves, they occur not only in residential premises for ordinary users, but also for the electricity suppliers themselves. Power surges are typically caused by malfunctioning lightning or switches, or by breakdowns in a substation.

To eliminate the surge, a varistor limiter is used, which is built into the design of the mains filter. For the device to work correctly, it must be connected to an outlet that is equipped with grounding. In this case, jumps and drops will be reset to the last node. Thanks to this approach, electronic equipment will remain intact and will not overheat.

Additionally, the filter is equipped with a capacitive unit, which is responsible for suppressing high-frequency interference. The element includes several inductors and capacitive capacitors. It is worth noting that many filters are equipped with a short circuit fuse.

In some situations, even the best models cannot cope with the protection of electrical appliances. The problem is too long voltage drops (2-4 milliseconds). Such a jump is easy to determine by eye, since at this time the bulbs begin to flicker. Bursts of a similar nature are formed during the launch of asynchronous engines of dishwashers, refrigerators and other large household appliances. To avoid undesirable consequences, it is necessary to acquire an uninterruptible power supply in a timely manner.

There are times when some houses with old electrical networks give out too low voltage, and this adversely affects the boards and other elements of the devices. Unfortunately, network filters are just as useless under these circumstances as they are with high surge. Buying specialized stabilizers that will prevent voltage drop can help.

Degree of protection

Network filters are divided into three protective groups: professional, advanced and basic. The first option is expensive and is suitable for users who regularly use surge-sensitive electronics. Advanced Elements does a good job of protecting home and office equipment. The basic group is designed to save appliances equipped with low power. In frequent cases, such options are a worthy alternative to conventional carrying.

Overheat protection

During operation, the surge protector generates a considerable amount of heat. This happens due to heating of the wiring and other internal elements of the device. In emergency situations, there is a tremendous release of heat, and this often ends in the burnout of equipment.

To protect the filter and electrical appliances, consider good overheating protection.To do this, a special sensor with temperature tracking is installed, which, in the event of a drop, turns off the filter.

Rated current indicators

Protective equipment is always equipped with a rated current limiter. As a rule, 10-16 A is considered a common parameter for most models. Based on these data, it is necessary to calculate the current indicator in accordance with the following formula: P \u003d U * I (for reference, U-voltage; P-power).

If you correctly use the above calculation, then taking into account a home network with a parameter of 220 V and a rated current of 10 A, you will get equipment with a limitation of no more than 2.2 kW.

Often, network filter manufacturers pre-set the maximum voltage values ​​\u200b\u200bin the case. It may not match the calculations, however, the indicator will be acceptable for high voltage. When the power significantly exceeds the prescribed tolerance, the bimetallic trip will automatically disconnect all electronic devices from the network.

Auxiliary ports

Most advanced models are equipped not only with sockets, but also with various ports for telephone and computer lines. It is also not uncommon to find a common USB connector that will allow you to charge a mobile device or other gadget. When the user chooses just such a model, he should make sure in advance of the appropriate parameter of the rated current (charging phones - 1 A; Charging tablets - 2.5 A).
