Leonardo ENERGY Academy launches its e-learning initiative with a comprehensive programme on power quality. The first course introduces the topic of power quality and then focusses on voltage dips and short interruptions.
The course should take between 12 to 20 hours for participants with an electrical engineering background. Participants are expected to finish the course by the end of February (28-02-2010).

This case study presents a methodology for improving power quality in an important industrial estate. A project was initiated to reduce the number of interruptions and enhance power quality in the estate and focused on reducing weak points in the power distribution system by inspecting distribution lines in both customer and utility areas. Once weaknesses were identified, corrective action would be taken and preventative measures taken to prevent re-occurance in order to provide high power availability to customers.

The Israel Electric corp. deployed a nationwide Power Quality Monitoring System (PQMS). The PQMS monitors the quality of supply of all of its high voltage costumers, as well as a sample of its medium voltage customers. The PQMS monitors both the voltages and the currents. The PQMS has been operational since October 2005. The paper presents preliminary measurement results obtained from the PQMS.

It happens more often than one cares to remember that short power interruptions affect key equipment (lithography equipment, vacuum pumps, ion implanters, etchers, memory testing benches…), bringing a production line to a halt. The same counts for short variations in the voltage supply level (dips or surges). Apart from those issues that seriously affect power availability and were also quantified by ECI’s PQ Survey, other PQ phenomena can also affect semiconductor plants’ equipment, namely uncontrolled harmonics.

This mini site presents the results of European PQ Survey with a focus on power quality critical sectors.
The main brochure explains why the industrial sectors interviewed lose annually upwards of €150 billion as a direct result of their electrical power installations not being sufficiently reliable and resilient for today’s and future operating demands.
