Here’s an article sent by one of our members Marvin M. It is about benefits of static var compensators to power transmission and distribution.

Introduction

The growth of residential and manufacturing industries means more energy demand. At present, almost all aspects of our lives, directly or indirectly depend on electricity. Unfortunately, power generation and transmission systems do not come up as fast. This is due to the high installation costs, as well as the growing environmental concerns. The ideal option now is to make the existing systems more efficient and economical to use.

One of the easiest ways is secondary installation of equipment primarily geared to achieve the two elements. One of the most effective additions is the Static Var Compensators. SVCs provide fast acting reactive power as needed to a system. This article highlights the benefits accorded by the SVC.

We received a nice article in our mailbox by an electrical engineer who wants to guide you for you to work safer. Electrical safety is an important topic, that’s why we accepted to publish his article as a back to basics…

how to work safer 1

“Anyone who works with electricity knows that it is not something to joke with! If someone says that he is not afraid of the electricity then he has not seen the damage it causes. Therefore, in this article I will examine how to work safer and how we can avoid future accidents after the job is done.

Today, one of our loyal members is dedicating an article to explain the behavior of diodes to various kinds of loads.

Introduction

Up till now we have studied quite a lot about the basics of diodes. Taking a quick revision, we came to know that how do semiconductor power diodes acts as switches, how their electrical properties change and how their current and voltage properties vary when they are connected in series or in parallel with each other.

These were some of the major characteristics of diode that we came to study up till now. One thing that would have knocked the mind of you guys would be that how would a diode react to a load attached to it. What kind of outputs can we get through the loads?

Well the answers to these questions are pretty simple…

Few weeks ago, we received this debate from Martin M., one of the visitor of the blog. So here is his interesting opinion on Power Factor Correction…

You too can send us a mail if you want to create a debate on the topic of your choice.

Are Power Factor Correction Units Necessary For Residential Consumers

You may have come across a nice, clear video on the importance of purchasing Power Factor Correction (PFC), also known as KVAR units for residential consumers. You may be luckier and actually met a salesperson, all verbose on how you can save a lot of money by installing a simple device between the power supply and the home appliances.

The selling point implicitly relies on people’s ignorance, as well as well laid-out misinformation and skewed facts. The main selling points for the scammers include the following

  • Home appliances such as refrigerators and washing machines are induction equipment and thus draw reactive power from the system.
  • Many industries use the PFC units to save energy, and so should you.
  • There are a number of positive ‘testimonials’ from satisfied clients.

New article from Nasir’s series of articles on Thyristors. You can also check the previous ones if you’ve missed them.

Introduction

Up till now we have become pretty much familiar with the properties, types and uses of thyristors. We came to know their diverse applications in the field of electrical technology. Different properties, operating characteristics, types, specifications and advantages of thyristors have been discussed and compared with the diodes, which are also a type of Power Semiconductor Switching devices we discussed.

Now this article brings a conclusion to our topic of power semiconductor switching devices, by discussing the last of our details of thyristors, which I hope would be an essential addition to your knowledge of power semiconductor switching devices.
