POWER QUALITY MONITORING - QUALITY DATA IN, QUALITY PROJECTS OUT

May 19, 2020 12:23:08 PM Will Magnussen

Power quality of an electrical system is used to describe the quality and inherent compatibility of power use and distribution in a network. For site connections, power quality is typically assessed in terms of harmonic voltage distortion, harmonic current distortion, voltage fluctuation, voltage unbalance and flicker.

GENERATOR CIRCUIT BREAKERS & OUT OF PHASE SWITCHING

Apr 15, 2020 4:03:35 PM Don Carbarns

Large Generator Circuit Breakers are like no others.  With ratings to match generators of 1000MW or more, they are massive devices with continuous current ratings in excess of 25,000A at voltages of the order of 24 - 36kV.  Currents of this magnitude would be considered to be fault currents in any other environment.

CHALLENGES OF INTEGRATING DISTRIBUTED AND RENEWABLE ENERGY RESOURCES WITH THE GRID

Dec 13, 2019 2:39:29 PM Brent Stewart

Advances in technology, as well as operational and economic benefits, are allowing energy production to be less centralised. Modern electricity grids are witnessing a growing number of connections of distributed energy resources, including gas and diesel generators and renewable's like wind and solar. The decentralised energy landscape brings with it several challenges for designers and grid operators.
