Global study finds continuing moderate growth in protective relay market with commitment to improving protection coordination and grid security practices

In 2016, Newton-Evans Research Company completed a six-month research study and survey of protective relay usage patterns in the world community of electric power utilities. Findings from 114 large and mid-size utilities in 28 countries pointed to some newer trends in adoption and use of protection...

The Fight Against Animal-Caused Power Outages

Every day across the country, animals enter substations for warmth, food, security, or simply out of curiosity. In many areas, wildlife intruding into power equipment has become the leading cause of outages – even more common than storms or vegetation.A single substation outage can cost tens...

Advancements in Dissolved Gas Analysis: NEI & Gassing Events

One of the most important steps when looking at DGA data is to decide whether the data support the existence of a fault that is actively breaking down the insulation before you try to use a triangle, pentagon, or gas ratio method to identify a fault type. Otherwise, you are diagnosing random...

Optimal Transformer Efficiency Using Weighted Average

In order to improve the efficiency of electrical distribution in commercial buildings, the US Department of Energy (DOE) introduced regulations with more stringent minimums on transformer efficiencies in January 2016. This was covered under the Code of Federal Regulations 10 CFR Part 431.192 and...

New options for insulation systems in power transformers

Introduction

The development of new insulation materials has been critical in the evolution of the design of power transformers. Insulation systems for liquid filled power transformers are a combination of materials that are aimed to provide the required electrical, mechanical, thermal properties together with a full chemical compatibility for successful operation of the transformer for several decades under defined operation conditions.

Materials enabling innovative power transformer solutions

The offering of solid materials like papers or...
