“…As the protection relay is probably the only device that is virtually mandatory on circuits of any significant rating, the functions previously carried out by separate devices are now found in a protection relay permitting significant cost savings and wiring simplification as compared with discrete protective relays, instruments, meters, recorders, and transducers of the past [7].…”

To ensure consistent reliability and proper operation, protective relay equipment must be evaluated and tested. This paper presents the requirements for testing the ac and d.c. auxiliary power supply of protective relays and the test results. The test severity levels, test setup , test procedures and test report are presented according to the IEC60255-11 Ed.2.0. A numerical relay commonly found in the power distribution systems is used for testing. The tests are carried out to determine the ability of the relay to withstand a variety of disturbances as specified in the international standard.

“…This approach can contribute to the reduction of the cost of the implementation o distribution wide PQ monitoring systems because it is not necessary to contemplate the cost of the instrumentation at actual customer service entrance locations. Again, the information that characterises the PQ levels being experienced by customers could be complemented with the PQ on selected utility distribution feeders by the using of dedicated PQ monitoring devices or Intelligent Electronic Devices (IED) [6], [7].…”

Power Quality Monitoring Integration into Distribution Automation through the Use of AMRAbstract-Power-quality events are of increasing concern for the economy because today's equipment, particularly computers and automated manufacturing devices, is highly sensitive to such imperfections. With volatile energy rates and a need to control costs, regional agencies and utilities are interested in technologies to meter distribution use and manage utility information. Metering technologies and communications systems have advanced to enable the development of Automated Meter Reading (AMR) Systems. Power Quality is one area where the AMR system can be very valuable. This paper investigates the challenges in the development of distributed power-quality monitoring system. The approach of this paper is divided into metering, data collection, archiving, analysis, and presentation. It also discusses system architecture, implementation, and provides general guidelines in the tailoring of PQ indexes. This paper describes the challenges and lessons learned from this work..

“…The simplest version of the PQ monitor would record only aforementioned powers, voltage and current variations. Again, the information that characterises the PQ levels being experienced by customers could be complemented with the PQ on selected utility distribution feeders by the using of dedicated PQ monitoring devices or Intelligent Electronic Devices (IED) [6], [7].…”
