H. is a fresh graduate from Dubai. Read her review about how to improve Power Factor. She gives you 3 ways to do it and it’s a nice back to basics type of article. Enjoy!
improve Power Factor

Power factor is a very common term in electrical applications because it determines the efficiency of an electrical system. It is a word that you will only hear when dealing with AC circuits as shown by its simple formula:

electrical-engineer-testimonyIn last month newsletter (newsletter#79), we introduced you to Mile, one of the members of the community.

From then on, he kindly decided to help providing the blog with material, and his 1st attempt is about power factor correction of networks.

Last time, D. Ros published a very interesting article about motors and drives. Today he’s at it again with synchronous motors and guess what? He proposed to publish a series of articles about motors! We thank him dearly.

Synchronous machines are highly regarded in the industry for their unique applications of high mechanical power demand, power system control, and plant power factor correction.

However, the uniqueness of these applications has lead into different regulation techniques oriented to meet their specific requirements.

Hi everybody, this is Steven Mill again with another article about a much discussed topic: voltage regulation and power factor.

If you’re interested in publishing articles like me, you can send a mail to the staff of the EEC community! I’ll be glad to read your essays as well.

Voltage regulation in commercial establishments

voltage regulation and power factor justification

Voltage regulation and power factor justification are very much interdependent, especially in commercial establishments. In most cases, it can be a very costly affair to obtain voltage regulation.

One of the best solutions to obtain voltage regulation is to employ large or parallel conductors in the circuit. This will help reduce voltage drop when larger loads are in operation.

How can power factor contribute to this?

  • It helps improve voltage
  • It lowers energy costs
  • It helps conductors to be more energy efficient
  • Transformers, buses, over current devices, conductors and switches, can all be utilized to their full capacities. This will in turn reduce the core investment as well as annual costs involved

Here’s a testimony that a professional from Boston, USA sent us two weeks ago. Eric S. wanted give you advices about static UPS, that’s why he wrote this article based on his experience.

You want to share you experience as well? You can send us a mail, we’ll be glad to publish it on the blog!

Introduction

static UPS for your data center 1

Taking a decision on the power requirements of a static UPS for your data center, can only be made after taking into consideration the various factors affecting it.

Owing to my experience in this field as a qualified UPS installation and maintenance expert, I can tell you that, one cannot choose the power size of a static UPS for a data center, solely depending on the power distribution scheme.

In fact, I strongly consider taking the following general and critical elements into consideration before you take a final decision:
