Introduction

3 Strategies to Reduce Peak Demand at Industrial Sites

The cost of investing in renewable energy sources is quite high. In addition, the costs of the main raw materials for electricity generation such as coal and oil are always rising. This means that the cost of electricity continues to increase despite the best of efforts.

Therefore, despite the long-term promises by the governments to reduce the cost of power, it is important that industries integrate short terms strategies to reduce peak power demand.

Last week we shared an article of the top 10 power quality problems, and you really like dit so today here’s the top 10 ways to increase energy efficiency and performance of pumping systems. Leave your impressions!

Top 10 Ways To Increase Energy Efficiency And Performance Of Pumping Systems

Almost all types of industries, big or small, need pumping systems to meet their fluid, especially, water utilities. Pumping systems should be designed to be as efficient and as energy saving as possible, keeping the individual needs and future demands in mind. However, ageing, improper maintenance, miscalculations while installation, selecting wrong specifications or a wrong model, can all lead to decreased pumping efficiency.

Below mentioned are the top 10 ways following which you can considerably increase the pumping performance, which in turn can save a lot of energy and money.

Hi, last time I told you about smart meter on middle voltage ; this time let’s see the basics of smart meter on low voltage.

Low is considered a voltage up to 1kV. There are two ways for measuring on low voltage:

  • Direct measuring – this method is used for current up to 100A (there are one phase and three phase electricity smart meters for this type of measurement)
  • Indirect measuring – this method is used for current over 100A (you need current transformers for low voltage)

Direct measuring

In the following pictures you can see how the different electricity smart meters look like depending on the measurement method.

These smart meters are to be mounted on small electricity consumers like small houses, apartments, small shops.

Hi, this is Steven Mill. It’s been a long time so I’m coming back with a back to basics article. Hope you’ll enjoy.

The electricity smart meter is a device that measures electricity in the same way as the ordinary electricity meter but with the difference that it measures and stores much more data and parameters than the ordinary electricity meter.

Below you can see how one electricity smart meter for middle voltage looks like.

Automation Systems

The subject that is fearful, important, very deep and very open for innovation. Yes we are talking about automation systems or in other words the brain of a system. It is the technology we need.

Everybody needs to learn the basics of it if they want to catch up with the modern industrial systems’ technologies. It is the latest trend. It is great and colorful.

Let’s get inside it: Automation Systems for industry and more.

Introduction

Automation Systems 1

An automation system (or any other control system) consists of two big parts; control and power. The control side is made up from electronic cards and some other small parts. The important side for electricians is the power side.

Today’s technology made it so complex that even if you are an electrician you need to know basic automation so that you are able to deal with the power side of automation systems that work with mid or low voltage levels.

You also have to make sure to not do something wrong with these systems, since they are so expensive and even small voltage changes due to power side can burn whole electronic side and result in lots of money loss to the factory; and I even don’t talk about the money loss due to the suspended system that will make you suffer a lot more.
