GROUNDING IN THE CELLAR OF THE PRIVATE HOUSE - IS IT POSSIBLE

When constructing a private house in a relatively small area, the problem of grounding often arises. Often, near a well-maintained house, it is simply not possible to find the necessary place to construct a grounding device. At the same time, in the cellar there is soil in which the grounding can be digged in.

NON-ELECTRODE METHOD FOR MEASURING GROUND RESISTANCE

NON-ELECTRODE METHOD FOR MEASURING GROUND RESISTANCE

Grounding parameters depend on many factors, and not all of them can be taken into account in the calculations. Therefore, after mounting the grounding, it is recommended to repeatedly measure its resistance at different times of the year. Grounding elements can oxidize and corrode, so it is also necessary to periodically measure the ground resistance even after you have verified that everything was done correctly. The standards available in Russia require measuring the ground resistance of electrical installations at least once every 12 years. For power poles with disconnectors, protective gaps, arresters, re-grounding of the neutral wire, the measurement of ground resistance is carried out annually. Also, annually selectively they measure grounding parameters at 2% of metal and reinforced concrete supports of power transmission line poles passing in populated areas.

PD (Surge protection device) - RELIABLE PROTECTION FOR COMPLEX ELECTRONICS

PD (Surge protection device) - RELIABLE PROTECTION FOR COMPLEX ELECTRONICS

The need to protect power networks from surge voltage arose almost immediately after people learned how to transfer electricity within a neighboring building. Often the cause of surge voltage is a lightning strike to a power line or the effect of lightning striking close to the cable. But there are other reasons, for example, switching processes in electric substations. Normally they should not lead to the appearance of dangerous surge voltage in the network, but in reality such surges appear due to worn-out equipment or insufficient staff qualifications.
