Inside you’ll find an introduction to energy storage and 3 articles on partial discharge (PD) topics including: an interview of Dr Detlev Gross and Markus Soeller, two acknowledged experts in this field; excitation voltages for PD testing of cables, and PD testing for transformers. Asset managers will want to read On-line testing of circuit breakers, which illustrates a pragmatic approach to efficiently surveying a circuit breaker fleet using first-trip and VDS testing. If protection schemes are among your areas of interest, you will appreciate the article on end-to-end testing. And those who know how challenging GIS testing can be will benefit from Boel Ekberg’s answers to typical questions she is asked. Transformer enthusiasts will find The high stakes of ignoring the mechanical health integrity of a transformer very informative and an article about dynamic testing of on-load tap changers useful in understanding the several variants of this test. You will also find inside an article about instantaneous torque in motors, which includes three case studies that will convince you of the value of this test. Another great case study is presented in A toolbox approach to fault location in LV power cables and those of you who work in industry won’t want to miss Maximising security of supply at Höchst Industrial Park. Did you know that HVDC transmission was around in 1904!? Open, enjoy and don’t forget to submit your answer to Megger’s third ‘Geek Challenge’ for a chance to win a prize. Publicerad 17 oktober 2020 Electrical Tester Magazine - March 2020 Explore our first issue of ET magazine, online. Inside you’ll find our feature article that discusses the coordinated efforts that will be required to successfully merge the electrified transportation sector with the electric utility sector, sharing the latest thinking, research and challenges ahead. Transformer testers/engineers will appreciate learning how several variables may unknowingly affect your TTR test results. A bird’s-eye view of the rise of transformer electrical, dielectric testing provides an overview of the tests necessary to fully assess a transformer’s dielectric health. As a necessary test to detect inter-turn insulation breakdown – one of the most common early initiators of motor faults, Motor insulation test voltages: How high is too high? dispels myths surrounding surge testing. The missing link in motor condition monitoring makes the case for electrical tests as vital requirements for achieving plant reliability – not just tests that detect mechanical problems. Andrea Bonetti explains ROCOF protection and how to test it. He also fields some of the most frequent questions he gets asked about IEC61850 in ET’s Q&A section. DC testing of vacuum integrity in MV switchgear explains the advantage of using DC over AC to test vacuum and the importance of the ‘DC’ your test instrument delivers. Marius Averitai discusses the choice of using primary or secondary injection to test a relay protection system; why, in many cases, primary injection is better; and important features in a primary injection test set. Read about a more effective approach for detecting ground/earth faults in TT distribution systems and more… Publicerad 18 mars 2020 Electrical Tester - Dec 2018 Tidning Publicerad 14 augusti 2018 Ladda ner PDF Electrical Tester - October 2013 Each issue of Electrical Tester has a range of hand-picked industry articles for high-voltage electrical engineers working on utilities. CIRED, the major International Electricity Conference and Exhibition, is the leading forum where the electricity distribution community meets every two years in various European venues, with a worldwide perspective and participation.

The SMRT way to test relays protective relay test sets also need generous short time ratings. The benchmark of performance for an amplifier with a 30 A continuous rating is a short-time rating of 60 A, plus the ability to supply up to 180 A at high power for instantaneous overcurrent test applications.
