Electrical Tester Magazine - July 2021
This ET issue offers tremendous electrical testing learning opportunities:A feature article that introduces virtual testing of protective relays – that’s right, and this method is already in practice today! DC high-speed circuit breakers – where are they found and how are they tested? Diagnostic testing of bushings, integrating newest learning from the last few years – amounting to far more diagnostic successes than ever before. An article that explores the relationship between thermal imaging and a dedicated low-resistance ohmmeter – read why, in an electrical preventative maintenance program, one to the other is the ‘jelly to the peanut butter’. Surge and lightning arresters – not so fast deciding that ignoring them is the best business practice Motor and generator articles x 4 (VLF, partial discharge, inrush current, and restricted earth fault (REF) protection). My transformer is wet! Now what? Foundational knowledge – what is a knee point, after all? All things protection and standards orgs’ work – Electropedia, IEC 60255, and IEC61850 in relation to the smart grid. Plus, get to know IEEE GPECOM and its ‘industry meets education’ ethos. Reading suggestions, historical interest, news and more…

Insulation resistance testers above 2.5 kV
Electrical insulation degrades over a period of time because of various stresses which are imposed upon it during its normal working life. The insulation has been designed to withstand these stresses for a period of years, which would be regarded as the working life of that insulation. This often runs into decades.

Case study: True dynamic resistance measurement
Pinpointing concealed problems inside a resistive-type OLTC before physical inspection - the application of true DRM.A maintenance team at the Electric Power Transmission Network in the City of Karbala performed routine electrical tests on a transformer including: winding resistance measurements (WRM), transformer turns ratio (TTR), short circuit impedance (SCI), excitation current, and line-frequency power factor (a.k.a. dissipation factor or tan delta). This case study looks into their investigations and their results.

Case study: Identifying aging and installation issues in an HV bushing
The subject 69 kV bushings are installed on a 10 MVA, 69/13.09 kV Dyn1 two-winding transformer. After completing on-load tap changer (OLTC) maintenance on this 1969-vintage transformer, the utility owner followed with electrical tests.
