Convergence optimization process

Hi everybody, it’s Mile, your fellow electrical engineer from Macedonia. I’m glad to discuss about efficient transformer design with you all today and I hope you’ll like my essay.

Energy efficiency is closely connected to the living environment and is one of the most important questions today. According the laws and regulations, it is important to use energy efficient equipment in the power systems, because of the benefits like energy saving.

megaphone-blueLike any other product or service nowadays, smart homes technology was part of science fiction stories. In May 6, 1950 Ray Douglas Bradbury first published his science fiction story “August 2026: There Will Come Soft Rains”. He just had a look in future and imagined how will homes look like in future and how will them be smart and interactive with surrounding conditions.

Although Ray’s prediction was perfect, the human development was faster than his expectation as smart homes became common few years ago.

Smart homes: why were they developed?

Smart homes were developed for two main ideas:

Consideration regarding future power requirement in a commercial, residential or office block is often ignored. Most of the installations are designed to only cater for the current power requirements. In some cases, the building owners will try and save costs by overlooking some of components that may appear as unnecessary expenses.

Michel, a french member of the community sent us this article, and we tought it was interesting for you to read it and give your impressions.

By the way, we all thank you for sharing knowledge with the Electrical engineering community. If you haven’t shared yet, you still can send us a mail.

Inserted into ventilation and air renewal systems in the buildings, the speed variator can deliver the right air flow in real time. Some considerable assets in terms of energy performance and maintenance equipments.

In addition to the use of electric motors at high-yield, the speed variator contribute to the reducing of energy consumption. Concerning the business buildings – service sector ones, and also the industrial buildings, two main categories of application are targeted. First, ventilation and then, domestic water pumping, notably in tall buildings or skyscrapers.

The effective management of the source of new air room by room, requires the setting up of a speed variator. Photo Credits : ATLANTIC.

The Electrical Engineering Community counts numerous members and we are lucky because they send us articles on a weekly basis. Today, let’s meet one of them who is willing to give you 5 practical tips to install a correct measuring system…

“Most electrical engineers face a number of problems while selecting a good measuring system. The reason being, they need to consider various types of measuring systems, current transformers, voltage transformers, wiring and grounding of the systems, etc., to finalize the most appropriate measuring system for electrical equipment.

I, being an electrical engineer myself (specializing in instrumentation), and having 15 years of experience in the similar field, have put together some practical tips that might help other electrical engineers in understanding “How to install a good measuring system?”. Following are some of them:
