To measure a low resistance connection could be a demanding task. If using an ordinary multimeter (DMM). It will make measurements of resistance values down to a tenth of an ohm.

This application note informs about how to perform testing of breakers with both sides grounded. Valid for both Mjölner 200 and Mjölner 600

To test a battery system with a higher voltage than the specified max voltage the system can be divided into segments, each with lower voltage and within the specified range. In these cases, it is critical to consider the grounding of the battery system. This application note explain those cases and describe a correct procedure.

A battery’s capacity is dependent on the ambient temperature. If the ambient temperature is high the capacity increase, but it will at the same time shorten the battery life. In the opposite direction, when ambient temperature is low, the capacity of the battery is reduced. This must be considered when performing a capacity test.

This document give additional information about the battery voltage monitoring system BVM and how those units are connected.

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.
