Worker Safety Using Infrared

Infrared safety: using thermal technologies to protect workers BY DOUG BARRY, FLIR Systems Disconnect switches, elbow connectors, cutouts, lightning arrestors, oil-filled circuit breakers, and other electrical components tend to heat up before they fail. The ability to detect overheating on such...

Automated metering, relay operation, RTU operation, electric management systems, remedial action schemes, SCADA, field reclosers, Synchrophasors, remote access, weather, and earthquake monitoring and future needs still yet...

WORKING IN THE THIRD DIMENSION

Typically, engineering consulting firms have been designing substations using two-dimensional computer aided design software (CAD) since the 1970s. This common technique produces two-dimensional drawings that are completed individually by designers. Any change to the design requires the designer to...

3-D Design for Electrical Substations

Exploring 3-D design techniques for electrical substations BY MIKE MINELLI, & HAROLD HARKONEN, Nordmin Engineering Since the 1970s, engineering consulting firms typically have been designing substations using two-dimensional computer aided design software (CAD). This common technique produces...

Rugged Tablets for Utility Fleet Vehicles

In reports analyzing the response of power utilities to incidents such as Hurricane Sandy, or the more recent ice storms on the east coast, one item has been remarkably consistent—the conclusion that communication requires improvements. The concern is not hard to fathom. Knowing accurately when...

Transient Analysis of Power Transformers Using Finite Element Method

A transformer relies on electromagnetic induction through coils to transfer electric energy between two or more circuits. Varying current in the transformer’s primary winding creates varying magnetic flux in the core, which produces varying electromotive force (EMF) or voltage in the secondary winding. Accurately and efficiently predicting currents and voltages on the primary and secondary windings can be challenging, especially for cores with non-linear material properties. Fortunately, numerical modelling techniques such as the Finite Element...
