How to minimize voltage drops? – 4 practical guidelines

journal1Hi everybody, it’s Steven Mill. Hope you’re enjoying your holidays.

I’ve personally been thinking about some topics to deal with on the blog and I thought about the one I’ve published in 2014 (September) about the inspection of voltage drop in conductors.

So today I want to go further and post 4 guidelines in order to help my fellows engineers. Enjoy!

According to NEC, a three percent voltage drop in branched circuits, and five percent voltage drop in feeders connected to branched conductors, will not to create major problems as far as energy efficiency and operation of general circuits is concerned.

But, a voltage drop greater than the indicated percentage (5%), can hamper the life as well as the operational efficiency of electrical circuits and equipment. In an attempt to minimize the voltage drops and keep them below 5%, a few practical guidelines are to be followed.

Below mentioned are the four practical guidelines, following which, voltage drops can be considerably minimized:

  • Increasing the number of the conductors or their size
  • Reducing the power load
  • Decreasing the length of the conductor
  • Decreasing the temperature of the conductor

We’ve been so glad to recieve a testimony in our boxmail this week. It is from a gentleman who wanted to share his career story with us.

Just check his path and don’t forget that you can also send us your testimonies or career stories by mail. But for now, let’s discover today’s story…

Educational Background

Whether I am a consultant or designer or both in the field of circuit board design, my services reach into both analog and power electronics. There are particular educational backgrounds required for this field.

Having started off doing my BS in electrical engineering I later took up my masters, both at the City College of New York, U.S.A. This is one of the few top engineering colleges in America.

Too much moisture in the transformer – how to measure and drying out?

As an electrical engineer, it’s important to keep your equipment clean to ensure a good maintenance.

What to do when there is “moisture” in the transformers? That’s the question this article will answer.

Moisture in the transformer

The term, “moisture in the transformer,” which is frequently used in the electrical industry, either refers to the water absorbed by the paper in the transformer, or the water that gets dissolved in the oil of the transformer.

Moisture can be found in various parts of a transformer’s insulation system. It can often get accumulated in the solid insulation of the transformer; get mixed up with the oil; and sometimes, it can also be found in the form of water accumulated at the bottom of the insulation core.

9 best recommended grounding practices for safety and power quality

grounding practices for safety and power quality 1

Grounding is the most important factor that governs the safety and the quality of a power system.

That’s on what Steven Mill wants to write today. Will you agree with his guidelines for safety and power quality?

“Grounding, also known as earthing, provides a safe way for the fault currents to pass on to the ground (neutral). This avoids sudden voltage spikes in the distributed network system, safeguarding the electrical equipment from permanent or premature failure. Grounding systems are generally designed keeping low-impedance paths in mind.

When a fault occurs, a low-impedance current flow path can result in discharging high volumes of current into the ground pretty quickly, keeping the equipment safe. Grounding also plays a vital role in transferring transients caused due to lightning strikes into the ground safely and quickly.”

Following are the recommended grounding practices according to me and maybe to you all:
