BPL: Deployment Challenges on Overhead MV Distribution Networks

In the last several years, utilities have been deploying and testing high-speed data communications systems using distribution circuits as the communications medium.

GETTING EQUIPPED: ‘Hardening’ the Power Substation

In the beginning, there was the electromechanical relay. With the advance of technology, solid state and later microprocessor relays began to be installed in substations, but while they offered tremendous improvements over their predecessors, they also came with at least one major drawback.

Focus on the Public Power Engineer: Orlando Utilities Commission

Editor’s note: I met Aaron Staley in Atlanta at IEEE’s Power Systems Expo.

Reducing Distribution Losses Without Breaking the Bank

With increasing concerns about energy efficiency, distribution loss reduction is again assuming a role of prominence in the utility industry.

AMR Communication Systems:Making an Intelligent Choice

An automatic meter reading (AMR) system stripped down to its most basic elements consists of meter endpoints, concentrating and collection devices, network servers and, finally, the utility’s meter data management system.

Everything’s Bigger- and Greener-in Texas

The mainstream media took notice in late February when TXU Corp. announced it was the target of a $45 billion cash-and-debt buyout by private equity firms Kohlberg Kravis Roberts & Co. and Texas Pacific Group.

Communications for Distribution Automation

Most automation by electric utilities has been applied in the substation and at the enterprise level.


The rugged design of the Distributed Discrete I/O Module (DDIO) from NovaTech allows it to be installed without any special environmental conditioning and to withstand the wide temperature range and electrical noise commonly found in HV substations.

Report Details Use of Geospatial Tech

The Geospatial Information & Technology Association (GITA) has published the 2006 Geospatial Technology Report.

A Look Back at DistribuTECH 2007

Although the show was two months ago, this is my first opportunity to write here about my reflections from DistribuTECH 2007 (www.distributech.com).
