Electrical measurements: monitoring the operation of the electrical network

It is absolutely impossible to imagine the development of technology, the functioning of objects of state importance or the daily life of every person without electricity. It should be understood that electricity is supplied through a complex system of networks. The electric system of Russia at the federal level unites all operating power plants. The entire country receives electricity from overhead power lines that use very high voltage — this saves energy. Consumers of electricity are not designed for such high voltages. To lower its level, transformer substations are used. They convert the voltage to a lower voltage and transfer the electricity to the switchgear. From there, consumers are supplied with electricity — electrical appliances, electric motors, etc.

A multi-level power grid requires careful attention to each object.The failure of any element of the system leads to serious consequences: interruption of power supply to large objects, damage to electrical equipment and fires. It is necessary to constantly monitor the state of the network, even in individual buildings or enterprises. For system inspection and prevention, electrical laboratory... This is an organization that deals with equipment testing and electrical measurements. In the transmission of electricity, not even in production, but in an ordinary city apartment, a lot of equipment is always involved: these are cables, and switches, and wires, and measuring devices, etc. Any of these details can fail. Electrical laboratory specialists test all sections of the electrical network and carry out repairs if necessary.

The insulation of the wiring deserves special attention. If the insulation is damaged and does not perform its function, a short circuit and fire may occur. Faulty wiring is one of the most common causes of fires. Regular measurement of insulation resistance helps to monitor the condition of the wiring and prevent disturbances throughout the network.
