The physicochemical features of the upper layers of the earth, where the currents of electrical installations flow, affect the state of underground metal structures. When designing and installing parts of pipelines and ground electrodes, knowledge about the electrical conductivity of the soil is required. The index of soil resistivity is of great importance. This parameter determines the level of corrosion hazard for buried metal products.
Soldering materials when working with radio electronics is a common thing. Learning to solder is easy, and with experience the skill will only grow. But the tool requires quality maintenance in order for it to work flawlessly. The craftsman needs to be able to properly tin the tip of the soldering iron so that the solder is held on it, while the tip cannot be damaged.
In single-phase mode, the voltage should be 220 volts, and in three-phase mode, 380 volts. But in reality, these numbers practically do not occur. Therefore, by checking the voltage value in the outlet, you can clearly verify the existence of phase imbalance. To bring the voltage value closer to standard values, you need to understand what is meant by the phrase "phase imbalance", its causes and possible remedies.
Electricity can be described as energy flowing through a closed electrical circuit. For its existence, a conductor is required, in which the electric field must be supported by a source of electricity. Most car models in their design provide for a thousand or more electrical circuits, independent of each other. This is one of the many examples of the impact electricity has on human life.
Situations when, due to the lack of capacity of city power grids, it has to be limited at some facilities, are quite common. You can solve this problem using a power limiter. As soon as the set parameters are exceeded, the device disconnects the consumer from the network. Also, this device allows you to protect electrical wiring from unauthorized connections.
The discovery of the current marked a new era in the development of mankind. It is impossible to imagine a comfortable existence of a modern man without energy carriers. But a new kind of energy is a reliable servant only in cases of complete vigilant control. In order to avoid negative consequences, the following safety measures are used: protective grounding, grounding and automatic systems for de-energizing networks.
Electrical appliances are present in every home today. The convenience of their use and their service life directly depend on the supplied voltage. Often, there are leaps in household networks, due to which modern electronics fail. Special devices such as overvoltage protection relays, residual current devices and others will help to protect it from breakdowns.
Electrical appliances surround man today at every step. Sometimes they break at the most inopportune moment. Moreover, the cause of the breakdown may be the most insignificant and the only problem in its elimination is the search for the place of the malfunction. To learn how to find it, just watch a video for dummies on how to use a multimeter. A simple device can facilitate the work of not only experienced electricians, but also novice crazy craftsmen.
Electrical injuries occur in everyday life and at work quite often, because people are surrounded by a large number of devices. To avoid electric shock, it is necessary to know in as much detail as possible what an electrical injury is, why it occurs and what safety rules exist when working with various devices.
