Overload Protection for Electric Motors

Thermal images are an easy way to identify apparent temperature differences in industrial three-phase electrical circuits, compared to their normal operating conditions. By inspecting the thermal differences of all three phases side-by-side, technicians can quickly spot performance anomalies on i... Read More

Why maintenance of the transformer is required?

1. Purpose and forms of transformer maintenance a. Purpose of transformer maintenance The primary purpose of transformer maintenance is to ensure that the transformer and accessories’ internal and external components are kept in good condition, “fit for the purpose” and can oper... Read More

Absence of Voltage Testing – An Update on Accepted Approaches

Absence of voltage testing is a vital step in the process of verifying and establishing a de-energized state of any electrical system. There is a specific and approved approach to establishing an electrical safe work condition with the following steps: determine all possible source of electrical... Read More

Six key trends that shaped Europe’s electricity markets in 2020

According to the Market Observatory for Energy DG Energy report, the COVID-19 pandemic and favorable weather conditions are the two key drivers of the trends experienced within the European electricity market in 2020.

Breakthrough in 3D magnetic nanostructures could transform modern-day computing

Scientists have taken a step towards the creation of powerful devices that harness magnetic charge by creating the first ever three-dimensional replica of a material known as a spin-ice. Spin ice materials are extremely unusual as they possess so-called defects which behave as the single pole of ... Read More

Considering the future of smart cities in uncertain times

There is a long tradition of seeing the future of cities in a utopian or dystopian light and it is not hard to conjure images in either mode for cities in 25 years, writes Eric Woods. At a time when predicting what will happen next month is hard, thinking 25 years ahead is both daunting and liber... Read More

Emerging markets poised to achieve smart metering despite COVID-19

When the ongoing COVID-19 crisis fades into the past and the global economy recovers, the long-term view for smart meter deployment and emerging market growth is strong, writes Stephen Chakerian. North America, Western Europe, and East Asia are largely concluding most of their first-time smart me... Read More

Hitachi ABB Power Grids selected for Thailand’s largest private microgrid

As Thailand moves to decarbonize its energy sector, the role of microgrids and other distributed energy resources is expected to play an increasingly important role. Thai energy company Impact Solar is partnering with Hitachi ABB Power Grids for the provision of an energy storage system for use i... Read More

A new way to look at the inner workings of tiny magnets

Researchers from NTNU are shedding light on magnetic materials at small scales by creating movies with the help of some extremely bright X-rays. Erik Folven, co-director of the oxide electronics group at NTNU’s Department of Electronic Systems, and colleagues from NTNU and Ghent University ... Read More
