Economic Cable Sizing and Potential Savings

This study by Egemin explores and quantifies the relationship between cable sizing in non-residential electrical installations and energy savings. Such savings can justify larger cross sections up to a point. A trade-off between additional investment and operational savings is to be made.

The analysis follows these steps:

World Electrical Safety Barometer

Residential electrical installations can be made entirely safe, thereby reducing the risk of electrically induced fires and electrocution to an absolute minimum. Ensuring this level of safety requires best practices in design, installation and inspection. However, the majority of countries around the world are missing the right mix of standards, regulation and education to make this happen.

Transformer Replacement Decisions

Transformer replacement before failure can be motivated by several legitimate reasons. These include environmental and fire safety regulations, changes in the load or the voltage level, an increased risk of failure due to transformer ageing, or the aim to improve the energy efficiency. This last motivation is less common, unfortunately. Replacing a transformer with a new one with higher energy efficiency will in many cases lead to a lower Life Cycle Cost of the device.

Analysis of the Power Network at the Point of Connection of Two Hoist Machines Converter Drives

The analysis of electrical power quality is aimed at improving power systems performance. A reliable analysis of power quality allows determining investment needs and their scope, so that a network could be operated continuously and in compliance with relevant standards. A correct analysis and measurements require the use of both the adequate instrumentation and measurement algorithms.
