\/><\/a><\/p>\n<p><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">As for the permissible voltage deviation from consumers, GOST stipulates that this value at the points of common connection is established directly by the network organization, which in turn must meet the criteria specified in these standards.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">In addition, I would like to note that during normal operation of the network, the permissible voltage deviation at the terminals of electric motors is in the range from -5 to + 10%, and for other devices no more than 5%. <\/span><span style=\"vertical-align: inherit\">At the same time, after an emergency, it is allowed to reduce the load by no more than 5%.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">By the way, I would also like to note that according to standards, the deviation on the power supply in electrical networks with a power of 0.4 kV should not exceed the 5% mark, in fact, as well as on the consumers themselves. <\/span><span style=\"vertical-align: inherit\">Total, 5% at source + 5% from consumers, we have 10% of the maximum allowed.<\/span><\/span><\/p>\n<p><span class=\"blockquote\"><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">It is important to know the causes of voltage deviation. <\/span><span style=\"vertical-align: inherit\">So the main reason is the seasonal or daily change in the electrical load of the consumers themselves. <\/span><span style=\"vertical-align: inherit\">For example, in winter, everything suddenly switches to heaters, as a result of which the power supply parameters decrease significantly. <\/span><span style=\"vertical-align: inherit\">About, what to do if the voltage is low, we told in the corresponding article!<\/span><\/span><\/span><\/p>\n<h2><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">Negative effect of parameter deviation<\/span><\/span><\/h2>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">In order for you to understand the full danger of voltage deviation in the network, we offer the following facts for reading:<\/span><\/span><\/p>\n<ol>\n<li><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">When the value drops below the normal range, the service life of electrical equipment is greatly reduced and at the same time, the possibility of an accident occurring. <\/span><span style=\"vertical-align: inherit\">In addition, the duration of the production process itself increases in technological installations, which entails an increase in the cost of production.<\/span><\/span><\/li>\n<li><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">In a home network, as we said before, voltage deviations reduce the life of light bulbs. <\/span><span style=\"vertical-align: inherit\">With a 10% increase in voltage, the life of conventional lamps is reduced by 4 times.In contrast, energy-saving lamps begin to flash when the voltage decreases by 10%, which also negatively affects the duration of their operation. <\/span><span style=\"vertical-align: inherit\">About the rest reasons for the flickering of fluorescent lamps you can find out from our article.<\/span><\/span><\/li>\n<li><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">For electric motors, due to the decrease in voltage, the current consumed by the motor increases. <\/span><span style=\"vertical-align: inherit\">This in turn reduces engine life. <\/span><span style=\"vertical-align: inherit\">If the voltage is even insignificant, it may seem 1% higher than normal, the reactive power consumed by the electric motor can increase to 7%.<\/span><\/span><\/li>\n<\/ol>\n<p><a href=\"https:\/\/my.electricianexp.com\/wp-content\/uploads\/2016\/08\/otklonenie-napryazhenia-1.jpg\" rel=\"nofollow noopener\"

style=\"vertical-align: inherit\"><span class=\"\" style=\"vertical-align: inherit\">To summarize, I would like to note that there are several modern ways to solve the problem: reducing voltage losses in the electrical network, which we wrote about in the corresponding article, as well as load regulation on outgoing lines and substation buses.<\/span><\/span><\/p>\n<p><span class=\"blockquote\"><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">So we checked the norms of voltage deviations in the network according to GOST. <\/span><span

Therefore, we have decided to devote our next paragraph to pointing out the most prominent features of the Jezli site.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">One of the most prominent features of the site is the proportionality of prices. On the Jeezly website, you do not have to worry about the imaginary prices of the products, as is the case with most sites that display their products on the Internet.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">The price of delivering products is very reasonable and not expensive, and the site accepts delivery to various countries, without forgetting that it accepts free shipping on some products.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">One of the features of the site is also the high quality of its products, as it is impossible to find a poor quality product. Rather, the Jezli website deals with the major companies, Philips, for example, and other famous brands, so you must remove from your mind the idea of \u200b\u200bthe poor quality of one of the products. <\/span><span class=\"VIpgJd-yAWNEb-VIpgJd-fmcmS-sn54Q\" style=\"vertical-align: inherit\">Another advantage of the site is that it does not specialize in one type of product, but rather you will find various types of products on it, for example, electrical appliances, hand tools, mechanical devices, paints, packages for establishing apartments, and many other types.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">Jeezly website also accepts what is known as the shopping cart, which makes it easy for you to filter the products you want to buy and put them in one package in order to be able to pay with the click of a single button.<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">Accepts multiple payment methods.<\/span><\/span><\/p>\n<h4><a href=\"https:\/\/gahzly.com\/\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-50673 size-full\" title=\"Components of an electrical circuit Components of an electrical circuit\" src=\"https:\/\/gahzly.com\/wp-content\/uploads\/2021\/12\/editor-1s-188px-15.gif\" alt=\"Electrical circuit components\" width=\"188\" height=\"188\" \/><\/a><\/h4>\n<h4><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">We are pleased that you visit our social media pages, where we publish exclusive offers on our website.<\/span><\/span><\/h4>\n<p><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">Our Facebook page\u00a0 <\/span><\/span><a href=\"https:\/\/www.facebook.com\/Gahzlystore\/\" target=\"_blank\" rel=\"noopener\"><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">is here<\/span><\/span><\/a><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\"> .<\/span><\/span><\/p>\n<p><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">Our Twitter account\u00a0 <\/span><\/span><a href=\"https:\/\/twitter.com\/gahzly1\" target=\"_blank\" rel=\"noopener\"><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\">is here<\/span><\/span><\/a><span style=\"vertical-align: inherit\"><span style=\"vertical-align: inherit\"> .<\/span><\/span><\/p>\n<\/div>\n<\/div>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What voltage deviation in the network is considered the maximum permissible Inconsistency of electrical network parameters with the required electrical power quality standards\u00a0 GOST 32144-2013 \u201cElectric energy.
